Release Notes

mock-server/mockserver-monorepo (org.mock-server:mockserver-client-java-no-dependencies)

v7.4.0

Added

• Dashboard: every language tab now generates typed client code. The composer's Java, Node.js, Python, Go,
  C#, Ruby, and Rust tabs construct each client's typed model — fluent builders and typed constructors matching
  the website examples — instead of embedding raw JSON, including full LLM response actions in Java. Every
  language's generated output is proven equivalent by executing or compiling it against the real client and
  comparing the serialized expectation with the registered JSON, and a CI gate compiles the generated Java
  against the built client on every build.

• Every client library now round-trips the full expectation model, proven by a shared fidelity harness. The
  Go, Rust, C#, Python, Ruby, and Node clients gained typed support for every expectation feature they previously
  dropped silently — chaos profiles, rate limits, forward-with-fallback and forward-validate actions, gRPC bidi
  responses, before/after actions, steps, capture rules, namespaces, LLM response payloads including moderation,
  rerank, and content filters, WebSocket frame matchers, response trailers, DNS matchers, and all body matcher
  variants. Forty-four server-validated kitchen-sink fixtures now run as round-trip tests inside each client's own
  test suite, with a ratcheting known-gaps ledger that fails CI if a documented gap silently regresses or a fixed
  gap is still excused.

• Dashboard: JWT and all-of body matchers are now authorable in the composer. The Advanced request form gains a
  JWT section (claims, issuer, audience, algorithm) and an all-of body matcher composing multiple sub-matchers,
  emitted in the exact server wire format and round-tripping on edit.

• Dashboard: the Java code tab is now complete and type-safe. Generated Java uses the real client API for
  priority, times, and time-to-live, scenario bindings, namespaces, and capture rules — proven by compiling a
  kitchen-sink snippet against the built client — and the Java client gains matching withNamespace and withCapture
  fluent methods. Actions the Java builder preview cannot represent show an honest notice instead of fabricated code.

• Dashboard: every captured flow is now a launchpad. A "Create From This" menu on traffic detail panes and
  log rows fans out into every subsystem pre-filled from that flow — create a mock in the composer, set a
  breakpoint, prefill a verification, or add chaos for the host. The traffic inspector also gains structured
  Request/Response tabs (headers tables and pretty-printed bodies, with the raw JSON tree kept as a tab),
  "Copy as curl" with shell-safe quoting and masked credentials, a Charles-style "Repeat" action (iterations,
  bounded concurrency, delay, live progress and cancel), a Proxyman-style diff pool with an editable ignored-headers
  list, an unmatched-count chip with why-didn't-this-match and generate-stub actions, and bulk
  "Promote to Mocks" over recorded traffic (PUT /mockserver/recordings/promote).

• Dashboard: previously server-only capabilities are now reachable from the UI. Validate recorded traffic
  against an OpenAPI spec (/trafficValidate), import GraphQL SDL schemas and mock SCIM providers, import Pact
  contracts, generate HTTP expectations from AsyncAPI specs, dry-run WASM modules against a sample request,
  reload persisted recording archives (NDJSON or from server disk), a preemption-simulation card and experiment
  history in Service Chaos, a control-plane Audit view, a standalone Scenarios view in the navigation, and a
  read-only Server Info tab (effective configuration with source tiers, bound ports plus bind-additional-port,
  proxy setup with CA download) alongside a server-side decoded-prompt LLM run diff.

• Dashboard: quick chaos and honest latency attribution. A one-toggle Quick Chaos strip (percentage slider
  over real per-request fault probabilities, per upstream host) makes fault injection approachable, and the
  traffic timing waterfall now distinguishes latency MockServer injected (chaos latency, configured response
  delays including the global delay, breakpoint holds) from real upstream/processing time — mock-served
  responses carry a timing block for the first time when they inject latency (a plain mock's recorded
  output is unchanged).

• Force a response-sequence variant per request. A request matching an expectation with multiple responses
  can force which variant it receives via a 0-based x-mockserver-response-index header. Forced requests
  consume times but never advance the sequential/switch rotation for other callers; the header is retained
  in recordings and filtered from every outbound forward, including WebSocket passthrough. Invalid values are
  ignored.

• Dashboard: faster first load, first-run onboarding, and one-click navigation. All views load lazily
  (initial bundle down from 259 kB to about 164 kB gzip), a Try It Now path on the get-started view creates a
  first mock, returning users get an open-dashboard shortcut, keyboard shortcuts move off
  browser-conflicting bindings with a ? help overlay, and matcher testing is available at the point of need
  in the composer and on every expectation row. The scenarios view details each scenario's states, bound
  mocks, and transitions with edit-in-composer actions, and the advanced composer models scenario bindings
  directly. The audit view explains the opt-in audit trail (and the demo enables it).

Fixed

• Dashboard: editing an LLM or otherwise exotic expectation now generates complete typed client code in
  every language. Fields the composer form cannot model — LLM responses with their full completion detail,
  response sequences, object callbacks, forward-validate, gRPC bidi, rate limits, and cross-protocol
  scenarios — were silently dropped from generated Python and Ruby code and embedded as raw JSON in C# and
  Rust; all languages now construct the client's typed model, guarded by a universal test asserting no wire
  field is ever absent from generated code.

• Registering forward-validate, forward-with-fallback, or gRPC bidi expectations no longer fails with a
  metrics error. The per-action counter constants for these action types were missing, and a guard test
  now asserts every action type has one.

• Generated Go code now compiles. All Go code generators — the dashboard expectation, verification, and
  load-scenario tabs, the retrieve-as-Go endpoint, and the website examples — emitted the client import without its
  /v7 semantic-import-versioning suffix, so generated code never resolved against the published module.

• .NET client: reading an object-callback expectation back from the server no longer throws. The
  responseCallback field was typed as a string while the server emits a boolean, losing the whole expectation.

• Python client: multipart body field matchers no longer vanish on registration. Multipart fields were emitted
  in an array form the server misroutes; they now use the server's canonical object form.

• Dashboard: editing a mock no longer shows phantom changes. An untouched edit round-trips to a zero diff — the
  explicit default forms of priority, times, and timeToLive are preserved instead of appearing as removals, and a
  genuine reset shows the explicit unlimited form.

• Dashboard: the Promote to Mocks button no longer wraps in a narrow traffic pane.

• Dashboard: editing an expectation no longer silently strips fields the form does not model. The composer
  now merges its form output onto the original expectation JSON, preserving scenario bindings, namespaces,
  response sequences, cross-protocol scenarios, and matcher fields such as keepAlive and socketAddress in
  both quick and advanced modes, with an alert listing the preserved fields.

• Dashboard reliability fixes. Paused breakpoint exchanges survive navigating away from the Breakpoints
  view; stream-frame editing is UTF-8 safe and surfaces encode failures; a reconnect re-sends the active
  request filter instead of silently streaming unfiltered data; an error-only push no longer blanks the
  panels; user-action errors persist until dismissed (and the banner is dismissible); mismatch dialogs report
  honest "differs on N field(s)" scores with remediation hints; and a response template rendering invalid
  output is now surfaced as a TEMPLATE_GENERATION_FAILED event instead of a silent 404 logged as a success.

• Dashboard performance, measured. Idle pushes no longer re-render every panel each second, hidden tabs
  buffer instead of processing WebSocket updates, and hot parse/search paths are cached — all verified by a
  committed benchmark suite (npm run bench in mockserver-ui) comparing against the pre-optimization
  implementations at small and large payload scales.

• Automated release publishing for the Ruby and PHP Testcontainers modules. The mockserver-testcontainers/ruby
  and mockserver-testcontainers/php modules now publish automatically as two new soft_fail release-pipeline
  components. tc-ruby (scripts/release/components/tc-ruby.sh) self-bumps the gem version.rb, builds inside the
  pinned Ruby image and gem pushes testcontainers-mockserver to RubyGems (credential from the existing
  mockserver-build/rubygems secret; skips gracefully if absent). tc-php (scripts/release/components/tc-php.sh)
  subtree-splits the module and pushes master + a version tag to the mock-server/mockserver-testcontainers-php
  Packagist mirror repo, mirroring the PHP-client publish; it skips gracefully until that mirror repo is provisioned
  (one-time setup — see mockserver-testcontainers/php/PUBLISHING.md). Both support --dry-run, are release-type
  gated (full/post-maven), and have soft post-release verification checks. See
  docs/operations/release-process.md.

• Go client: jwt/allOf matchers, a /v7 module path, and a bundled Testcontainers client. The Go
  client (mockserver-client-go) gains typed jwt request-matcher and allOf body-matcher builders (matching
  the other client libraries). Its module path now carries the required Semantic Import Versioning suffix —
  github.com/mock-server/mockserver-monorepo/mockserver-client-go/v7 — so it is properly go get-able as a
  dependency (a future v8 becomes /v8); update imports to add /v7. With that fixed, the Go Testcontainers
  module now bundles the client and exposes container.Client(ctx) returning a ready-to-use client pointed at
  the container's mapped host and port, instead of only documenting manual construction.

• Typed client-library support for the jwt request matcher and allOf body matcher. The two new
  matchers are now first-class in the client libraries as well as the server: the OpenAPI spec, the generated
  Node/TypeScript types (jwt, Jwt, and the ALL_OF / bodyAllOf body variant), and the Java model
  (request().withJwt(jwt()...), withBody(allOf(...))) all expose them, and every other client library can
  send them over the REST wire format. Consumer docs gain Java and Node examples for both matchers.

• Automated package-manager release channels for the CLI (Homebrew, Scoop, winget, Chocolatey, SDKMAN!, asdf/mise).
  Six new release-pipeline components (scripts/release/components/{homebrew,scoop,winget,chocolatey,sdkman,asdf}.sh)
  publish/update these channels automatically as a soft_fail group after the binary-bundle step, distributing the same
  self-contained jlink bundles (mockserver-<version>-<os>-<arch>.tar.gz/.zip, each carrying its own trimmed Java
  runtime) that the binary component uploads to the GitHub Release. A new tap formula (mock-server/homebrew-tap,
  brew install mock-server/tap/mockserver) is added — complementary to, and separate from, the JAR-based homebrew-core
  formula (still bumped by BrewTestBot). Each channel renders its manifest from the real published bundle checksums,
  supports --dry-run, and skips itself gracefully (never breaking the release) when its target repo or API secret is
  not yet configured. See packaging/<channel>/release-component.md and docs/operations/release-process.md.

• WebSocket proxy passthrough + frame recording. MockServer can now proxy WebSocket connections through to a real
  upstream server, not just mock them. When a WebSocket upgrade request (GET + Upgrade: websocket) arrives in proxy
  mode and no WebSocket mock expectation matches — or it matches a plain FORWARD expectation — MockServer completes
  the upstream connection (honouring ws/wss scheme and TLS), relays the 101 Switching Protocols handshake, and
  relays frames bidirectionally (text, binary, ping, pong, close) until either side closes. This lets a system under
  test pointed at MockServer as a proxy reach a real WebSocket backend. The relayed traffic is recorded: the upgrade
  exchange is logged as a FORWARDED_REQUEST (request = the upgrade, response = 101 carrying a JSON transcript of the
  relayed frames with direction/opcode/payload), so retrieveRecordedRequests and the dashboard show the WebSocket
  traffic. The transcript is flushed to the log once, on connection close. Frame recording is bounded per connection by
  the new webSocketProxyMaxRecordedFrames configuration property (default 1000; set to 0 to disable frame
  recording — the handshake is still recorded) plus an absolute 8MB transcript cap, following the maxLogEntries
  memory-management philosophy. The upstream TLS leg uses the forward-proxy trust manager
  (forwardProxyTLSX509CertificatesTrustManagerType, default ANY) so real wss backends are reachable, and the same
  forwardProxyBlockPrivateNetworks SSRF guard the matched-forward path enforces applies (a WS upgrade to a
  loopback / RFC1918 / cloud-metadata target is refused with 502). A slow peer cannot exhaust memory — the relay
  applies standard writability-based backpressure. An opt-in webSocketProxyIdleTimeoutSeconds (default 0, off)
  reaps abandoned relays. For a WS upgrade matched by a plain FORWARD expectation, Times/verify apply but
  response-shaping features (delay, rateLimit, chaos, breakpoints, drift) do not — use the WEBSOCKET_RESPONSE
  mock action for frame-level control. Scope (v1): HTTP/1.1 upgrade relay (plain and TLS upstream); HTTP/2
  extended-CONNECT WebSocket is not yet relayed. See
  docs/code/netty-pipeline.md.

• Seedable template faker for reproducible fixtures — new templateFakerSeed property. The template
  faker sample-data helper (Velocity $faker, Mustache {{faker.*}}, JavaScript faker) can now be seeded
  deterministically. templateFakerSeed defaults to 0, which leaves faker unseeded so it produces different,
  random values on every render (behaviour unchanged); a non-zero value seeds a per-engine Faker so
  faker-driven templates generate reproducible fixtures across runs — the template analogue of the OpenAPI
  example generator's fixed-seed model. Determinism is strongest for sequential (single-threaded) generation.
  Wired through the config trio (ConfigurationProperties / Configuration / ConfigurationDTO) and honoured
  by all three template engines. See docs/code/configuration-reference.md.

• Per-host upstream mTLS — new forwardProxyClientCertificatesByHost property. Outbound client
  authentication (mTLS to the upstream) was global-only; it can now vary by upstream host. The property is a
  comma-separated list of host=certificateChainPath;privateKeyPath entries — a matching upstream host
  (case-insensitive) is sent that host's cert/key pair for client authentication, and any host without an entry
  falls back to the global forwardProxyPrivateKey / forwardProxyCertificateChain pair (default empty, so
  behaviour is unchanged). Contexts are cached per mapped host while all unmapped hosts share one context, so a
  forward proxy that sees many upstreams cannot grow the cache without bound. See
  docs/code/tls-and-security.md.

• Testcontainers modules for Ruby and PHP, plus a wired client on every polyglot module. MockServer now
  ships official Testcontainers modules for eight languages — Ruby (testcontainers-mockserver, RubyGems)
  and PHP (mock-server/mockserver-testcontainers, Packagist) join the existing Java, .NET, Node.js, Python,
  Rust and Go modules. Both new modules start the mockserver/mockserver image, wait for
  PUT /mockserver/status → 200, and expose connection helpers (endpoint / getEndpoint, secure_endpoint,
  server_port, host).

  • A wired client on every module. Each polyglot container now returns a ready-wired MockServer client
    pointed at the mapped host/port, mirroring the Java module's getClient(): get_client (Python, Ruby),
    getClient() (Node, .NET), getMockServerClient() (PHP — the inherited Testcontainers getClient() is
    reserved for the Docker client), and client() / async_client() (Rust). The language's MockServer client
    is now a dependency of its Testcontainers module. (Go instead documents constructing the client from
    ctr.Host(ctx) / ctr.ServerPort(ctx) via mockserver.New(host, port): mockserver-client-go is
    published at v7.x without a /v7 module-path suffix, so bundling it would make the Go Testcontainers module
    itself unresolvable for downstream go get.)
  • Version-matched default image, no more hard-pinned tags. Every module now derives its default image tag
    (mockserver-<version>) from the MockServer client version — or, for Go, from the module's own version —
    falling back to the mutable latest tag when the version cannot be resolved, mirroring the Java module,
    instead of a hard-coded tag that goes stale.

• WASM response shaping (host ABI v3). WASM custom-rule modules can now compute the response, not just
  match the request. A module that exports an optional shape_response(i32 ptr, i32 len) -> i64 function is
  invoked after a match with a JSON envelope {version:3, request:{…v2 request…}, response:{statusCode, headers, body}} describing the response the matched expectation would return; it returns a (possibly
  partial) response JSON {statusCode?, headers?, body?} that MockServer applies — replacing the status,
  merging headers, and replacing the body — enabling WASM-computed dynamic responses. Fully backward
  compatible: modules without the export stay pure predicates, and a module can export both
  match_request and shape_response to match first, then shape. Fail-safe: any trap, invalid JSON, or an
  over-sized return (capped at 1 MiB) leaves the response unshaped and logs once per module — a broken
  shaper never fails the request. The examples/wasm/sdk-rust authoring SDK gains ShapeEnvelope,
  ShapeResponse and a ResponseBuilder, plus export_shape_response! /
  export_match_and_shape_response! macros, and a new examples/wasm/rust-shape-response example module
  (matches POST /shape, sets X-Shaped: true, and rewrites a JSON body field). POST /mockserver/wasm/test
  accepts an optional candidate response and returns the shaped response so IDEs can preview shaping. See
  docs/code/wasm-rules.md and the WASM Custom Rules page.

• SCIM list endpoints now support sorting. The mock SCIM 2.0 provider's GET {basePath}/Users|Groups
  listing accepts the standard sortBy and sortOrder query parameters (RFC 7644). sortBy is an
  attribute name or nested dotted path (e.g. name.familyName); sortOrder is ascending (default) or
  descending. Comparison is case-insensitive and resources with no value for the sort attribute are
  always ordered last. Sorting is applied after any filter and before startIndex/count pagination; a
  malformed sortBy path or an invalid sortOrder returns a 400 error envelope (matching how an invalid
  filter is rejected), and the ServiceProviderConfig now advertises sort as supported.

• More realistic LLM token estimates and subword streaming by default. The approximate TokenCounter
  behind inferred usage counts and token-based quotas now approximates GPT-style subword (BPE)
  segmentation instead of a plain characters÷4 blend, landing within roughly ±15% of a real tokenizer for
  ordinary English prose (validated against GPT-4 cl100k_base reference counts). Streaming LLM responses
  now emit finer, subword-sized deltas by default (via streamingPhysics.subwordStreaming), so a
  streamed response streams closer to a real provider's per-token cadence out of the box. Behaviour
  change: because a stream now carries more, smaller real-token deltas at the same tokensPerSecond, its
  total duration is slightly longer than before, and the per-provider streaming wire output is finer-grained.
  All streaming-physics timing semantics are preserved (each delta is still one physics event). To restore
  the previous whole-word (whitespace-boundary) streaming, set streamingPhysics.subwordStreaming to
  false explicitly.

• Editor extensions can start MockServer without Docker. Both the VS Code extension and the JetBrains/IntelliJ
  plugin gain a Start (binary, no Docker) command/action that launches MockServer from the self-contained binary
  bundle (a jlink-trimmed Java runtime + the shaded jar + launcher — see scripts/build-binary-bundle.sh), so
  corporate machines without a Docker daemon can run a local server straight from the editor. The bundle is taken
  from a configured local path (mockserver.binaryPath in VS Code, Binary bundle path in JetBrains settings) —
  either the bin/mockserver launcher or the unpacked bundle directory — or, when unset, downloaded on demand
  (after an explicit confirmation) for the current OS/architecture from the GitHub release matching the
  extension/plugin version and cached (under the extension's global storage / IDE system cache). Checksum
  verification against the published .sha256 sidecar is fail-closed: a digest mismatch always aborts, and a
  sidecar that cannot be fetched (common behind a TLS-inspection proxy, where the small sidecar fetch fails while
  the large archive succeeds) aborts too unless the user explicitly confirms installing unverified. The launched
  process is tracked for a matching Stop (binary) and terminated on editor/IDE shutdown so it never outlives
  the editor holding the port: VS Code streams its output to the MockServer output channel and its download honours
  the editor's http.proxy / system-proxy settings; JetBrains runs it as a tracked background process registered
  for IDE-shutdown cleanup. Docker-based Start (Docker) is unchanged. See the
  IDE Extensions page.

• Match requests by the claims inside a JWT (jwt request matcher). An expectation can now route on a
  JSON Web Token carried in a request header — withJwt(jwt().withClaim("sub", "user-1").withClaim("scope", ".*admin.*")) matches only requests whose bearer token carries those claims (each claim value is an exact
  string or a regex, with ! negation supported). Convenience fields issuer (iss), audience (aud,
  string or array) and algorithm (JOSE header alg) are provided, and the header name (default
  authorization) and scheme prefix (default Bearer) are configurable. The token's header.payload is
  decoded with base64url + JSON and its signature is deliberately not verified — this is request matching
  for test routing, not authentication (the control-plane JWT auth stack is unchanged). A request with no such
  header, or a malformed token, simply does not match (it never raises an error). Exposed on HttpRequest and
  through the JSON wire format ("jwt": { "claims": { ... }, "issuer": "...", "audience": "...", "algorithm": "..." }) and JSON schema. (Java server + JSON wire format; typed client-library wrappers to follow.)

• Compose several body matchers that must all match (ALL_OF body / allOf). A request body can now be
  matched against several body matchers at once, where every one must match the same body — for example
  withBody(allOf(jsonPath("$.name"), jsonSchema(schema), regex(".*value.*"))). This reuses the existing body
  matcher implementations without changing any of their semantics; each component keeps its own not flag and
  the composite honours its own not (negate the whole conjunction) and optional flags. Serialised as
  {"type":"ALL_OF","bodyAllOf":[ ... ]} and accepted wherever a body matcher is accepted. (Java server + JSON
  wire format; typed client-library wrappers to follow.)

• Fluent MockServerClient.builder(). The Java client gains a discoverable fluent builder that
  covers every existing construction dimension in one place — host (default localhost), port
  (default 1080), contextPath, Configuration/ClientConfiguration, portFuture, plus TLS
  (secure), proxyConfiguration, control plane JWT (controlPlaneJWT) and requestOverride that
  previously required post-construction with... setters. MockServerClient.builder().host("localhost").port(1080).build()
  is equivalent to the corresponding constructor call. The eight existing constructors remain fully
  supported and are not deprecated; the builder simply delegates to them, so it introduces no
  behaviour change. Misconfiguration stays loud (an empty host throws IllegalArgumentException, and
  portFuture(...) cannot be combined with host/port/contextPath). See
  docs/code/client-and-integrations.md and the
  MockServer Clients page.

• Observability quick-win bundle — Grafana dashboard, Helm ServiceMonitor, and a durable audit file sink. Three
  independent additions that make MockServer easier to monitor in production:

  • Standalone Grafana dashboard for the server metric family. examples/grafana/mockserver-server.json (with a
    README) is an importable dashboard charting request throughput and match outcomes (via the new _total
    counters), request-latency percentiles, registered expectations/actions, per-upstream forward/proxy health,
    dropped-log-events and chaos counters, and the JVM runtime gauges — every panel references a metric documented in
    docs/code/metrics.md. It exposes a datasource variable so it imports against any Prometheus data source, and
    is kept separate from the existing k6 load-injection dashboard.
  • Optional Prometheus Operator ServiceMonitor in the Helm chart. serviceMonitor.enabled=true (disabled by
    default) renders a monitoring.coreos.com/v1 ServiceMonitor scraping /mockserver/metrics, with
    namespace/interval/scrapeTimeout/path/scheme/honorLabels/labels/namespaceSelector/relabelings
    values. User-supplied labels are merged over the chart labels (user wins) so a release label for the
    Prometheus serviceMonitorSelector overrides cleanly. Requires the Prometheus Operator CRDs and
    mockserver.metricsEnabled=true.
  • Durable NDJSON control-plane audit file sink. New auditLogFile property (empty default = off): when set,
    each recorded audit entry is also appended as one JSON object per line to the file, giving a restart- and
    reset-surviving trail that outlives the bounded in-memory ring. Implemented as a separate AuditFileSink
    writer that only observes the same entries — the in-memory ring is untouched (honouring the "never a sink"
    contract). Path resolved once on first write, parent dirs created, append-only (rotation out of scope), and
    fail-soft (a single WARN then self-disable on IO error, never crashing request handling).

• OpenAPI request validation now checks style/explode-serialised array and object parameters. When you
  validate traffic against an OpenAPI spec (contract/traffic validation, the verify_traffic MCP tool, or an
  OpenAPI-backed expectation returning 400 on non-conforming requests), array/object query, path and header
  parameters were previously skipped unless the value already looked like JSON — so a malformed list or object slipped
  through. MockServer now decodes each parameter from its style/explode serialisation before schema validation:
  query form/spaceDelimited/pipeDelimited/deepObject, path simple/label/matrix, and header simple,
  for both explode values, with the OpenAPI defaults applied when the spec omits them. Decoding is type-aware
  (each element/property is coerced to the JSON type its item/property schema declares) so a request that was valid
  before stays valid — only values the spec genuinely rejects (e.g. a non-integer element in an items: integer
  array, or a non-integer property in a deepObject) now fail. It is fail-open: any value that cannot be soundly
  reconstructed (a non-primitive item/property, or an unsupported style combination) skips the schema check exactly
  as before, while required-presence is still enforced. Note this is a (spec-conformant) behaviour change for
  traffic validation: non-conforming style serialisations that previously slipped through unchecked can now return
  400 — e.g. a comma-delimited list sent where the spec declares the default form/explode: true (which expects
  repeated parameters) is decoded as a single element and validated as such. One known edge: an empty value for a
  non-explode form array decodes as a single empty-string element rather than an empty array.

• OpenAPI example generation honours discriminator, readOnly and writeOnly. Generated examples (OpenAPI
  import to expectations, run_contract_test/run_resiliency_test, load scenarios) are now more faithful: for a
  oneOf/anyOf schema with a discriminator, a concrete subschema is chosen and the discriminator property is set
  to the matching mapping key (or the referenced schema name when no explicit mapping is given), instead of blindly
  taking the first subschema; and readOnly properties are omitted from request examples while writeOnly
  properties are omitted from response examples, per the OpenAPI spec. Existing callers that do not specify a
  direction are unchanged (no readOnly/writeOnly filtering).

• gRPC forward proxy + record/replay — bring the record-then-mock workflow to gRPC. Until now gRPC
  support was mock-only: MockServer could decode inbound gRPC to JSON and serve mocked responses, but could
  not forward a gRPC call to a real upstream gRPC server. Now, when a gRPC request (HTTP/2 +
  application/grpc) matches a FORWARD-class expectation — or arrives in proxy mode with no matching
  expectation — MockServer re-encodes the decoded request back into gRPC-framed protobuf, relays it to the
  upstream gRPC service, decodes the framed protobuf response back to JSON, and re-frames it for the calling
  client. The forwarded exchange is recorded in the event log as a FORWARDED_REQUEST carrying the decoded
  gRPC method path, status, and (when a proto descriptor is registered) the decoded message JSON, so
  retrieveRecordedExpectations (and promote_recordings) produce a replayable gRPC mock — the same
  record → snapshot → replay loop already available for HTTP/SSE. A non-OK terminal grpc-status/grpc-message
  delivered by a real upstream in HTTP/2 (or chunked HTTP/1.1) trailers is preserved through the relay and the
  recording, rather than being defaulted to OK. Unary and client-streaming request bodies
  (single JSON object / JSON array) and unary or server-streaming responses (one or more frames) are handled.
  Decoding of the recorded exchange requires the proto descriptor to be loaded on the proxy (via
  grpcDescriptorDirectory / grpcProtoDirectory / PUT /mockserver/grpc/descriptors); without descriptors
  the gRPC bytes are still forwarded verbatim but recorded undecoded. Full bidirectional streaming forward is
  out of scope (it is driven by the multiplex bidi pipeline, not the request/response forward path). The
  transform is fail-safe — a non-gRPC request, an unknown method, or any conversion error leaves ordinary
  HTTP forwarding byte-for-byte unchanged (GrpcForwardTranslator, org.mockserver.grpc).

• The dashboard now warns when log events are being silently evicted — the #​1 cause of "verification
  intermittently fails". When MockServer's log ring buffer fills up, the oldest events are dropped, so
  verifications and the dashboard silently miss requests. The Dashboard and Traffic views now show a
  dismissible warning banner whenever the server's mock_server_dropped_log_events counter is non-zero
  ("The log ring buffer is full, so the oldest events have been dropped (N so far)…"), pointing at
  maxLogEntries / ringBufferSize with a link to the performance docs. The banner reuses the existing
  Prometheus metrics endpoint the Metrics view already polls (no new server endpoint) and stays hidden on a
  healthy server or when metrics are disabled. It re-appears only if more events are dropped after a
  dismissal.

• Bulk actions in the dashboard: multi-select expectations and captured requests to clear them in one go.
  The Active Expectations list and the Traffic inspector each gained a "Select" mode with per-row checkboxes,
  a select-all toggle and a running count. "Delete selected" removes the chosen expectations (batched per-id
  clears) and "Clear selected" removes the chosen captured requests from the log, each behind a confirmation
  dialog. Compare mode in the Traffic inspector is unchanged (still capped at two rows for a diff) and is
  mutually exclusive with the new uncapped select mode.

• Migration importers for WireMock, Mountebank and Mockoon. Teams moving off another mock tool can now
  convert their existing stubs into MockServer expectations in one shot through the existing
  PUT /mockserver/import endpoint, via ?format=wiremock, ?format=mountebank or ?format=mockoon
  (all three are also auto-detected from the JSON structure when no format is supplied). Each importer maps
  the foreign matcher/response model onto MockServer's:

  • WireMock stub JSON (single stub, mappings array, or bare array) — method/urlPath/urlPathPattern/
    urlPattern/url, queryParameters/headers predicates (equalTo/matches/contains), bodyPatterns
    (equalToJson/matchesJsonPath/contains/matches/equalTo), response status/headers/body/
    base64Body/jsonBody/fixedDelayMilliseconds, fault → connection error, proxyBaseUrl → forward,
    WireMock scenarios → MockServer scenarios, and priority (inverted, since WireMock 1 = highest).
  • Mountebank imposters (http/https only; tcp/smtp skipped with a warning) — equals/deepEquals/
    contains/matches/exists/startsWith/endsWith predicates → matchers, is → response, proxy →
    forward, fault → connection error, _behaviors.wait → delay, _behaviors.repeat → Times, and multiple
    is responses → one cycling multi-response expectation.
  • Mockoon environments — each route → expectation(s) with :param path segments converted to regex,
    response statusCode/headers/body and latency → delay, response rules → matchers (with descending
    priority so array order and the default catch-all are preserved), and responseMode SEQUENTIAL/RANDOM
    → the matching MockServer response mode.

  Every foreign construct with no faithful MockServer equivalent (TCP imposters, XPath/XML predicates, response
  templating/transformers, compound and/or/not predicates, JavaScript inject, unsupported rule
  operators, …) produces a structured warning in the response body — { "expectations": [...], "warnings": [...] } — rather than being silently dropped. Secret redaction is on by default (as for HAR/Postman/Pact
  import). No new runtime dependencies (Jackson only). See docs/code/request-processing.md and the
  Importing Expectations page.

• AsyncAPI broker mocking — Kafka Avro/Confluent Schema Registry, AMQP subscribe/verify, and MQTT 5. The
  mockserver-async module gains three enterprise-broker parity features, all driven from the existing
  PUT /mockserver/asyncapi brokerConfig:

  • Kafka Avro in the Confluent Schema Registry wire format. Set kafkaValueFormat: "avro" to publish and
    consume Kafka messages framed as magic byte + schema id + Avro binary, byte-compatible with real Confluent
    Avro producers/consumers. Two modes: registry-backed (kafkaSchemaRegistryUrl — the schema is registered
    under <topic>-value on publish and resolved by id on consume) and registry-less (an inline avroSchema
    plus a fixed avroSchemaId). Consumed Avro is decoded back to JSON so .../asyncapi/verify substring and
    JSON-path checks work unchanged. Implemented with Apache Avro (Apache 2.0) plus a hand-rolled 5-byte
    framing and a minimal JDK-HttpClient Schema Registry REST client — deliberately avoiding the
    Confluent Community License serde stack. Protobuf is deferred.
  • AMQP (RabbitMQ) subscribe/verify. AMQP is no longer publish-only: with consume: true, MockServer now
    subscribes to and records AMQP messages for verification, mirroring Kafka/MQTT. The queue is derived from the
    channel's bindings.amqp (queue-based consumes the named queue; routingKey-based declares the exchange and
    binds a private queue on the routing key).
  • MQTT 5. mqttProtocolVersion: 5 selects the Paho v5 client for publish and subscribe (default 3/3.1.1);
    v5 additionally delivers message headers (e.g. correlation IDs) as MQTT 5 user properties on publish and
    records them as headers on consume — which MQTT 3 cannot carry.

  New Docker-gated live-broker tests (Kafka, RabbitMQ, Mosquitto) plus non-Docker serde/wire-format unit tests
  cover all three. See docs/code/async-messaging.md.

• Mock OpenAI Realtime & Gemini Live voice APIs over WebSocket — new RealtimeMockBuilder. MockServer can
  now mock the two dominant realtime (voice) LLM protocols so agents/apps that use them can be tested offline,
  with no real API and no audio hardware. A new pure event codec pair in mockserver-core
  (org.mockserver.llm.realtime.OpenAiRealtimeCodec / GeminiLiveCodec) generates the provider-correct
  WebSocket event stream for one scripted assistant turn, and the Java client RealtimeMockBuilder
  (org.mockserver.client) wires it into a standard httpWebSocketResponse expectation — an initial pushed
  session.created plus per-incoming-frame matchers — so no new action type, DTO, or JSON schema is
  required (exactly as A2A streaming reuses httpSseResponse). OpenAI Realtime (GA 2025 event protocol,
  wss://.../v1/realtime): pushes session.created on connect, acknowledges session.update and
  conversation.item.create, and answers each response.create with the full lifecycle — response.created
  → response.output_item.added → response.content_part.added → per-token
  response.output_audio_transcript.delta + response.output_audio.delta (audio modality) or
  response.output_text.delta (text modality) → the matching *.done markers → response.done with usage.
  Gemini Live (BidiGenerateContent): answers setup → setupComplete and each clientContent turn with
  a streamed serverContent chunk sequence + generationComplete/turnComplete carrying usageMetadata.
  Streaming timing follows a deterministic tokensPerSecond / time-to-first-token model; audio bytes are opaque
  silence placeholders (the fidelity target is the event protocol, not audio DSP). Deferred protocol corners
  (server VAD / input-audio-buffer events, function-call output items, Gemini toolCall/realtimeInput, etc.)
  are documented in docs/code/ai-protocol-mocking.md rather than half-implemented.

• Prometheus _total counters for the five monotonic metrics (correct rate()/increase()). The five
  genuinely-monotonic counts — requests_received_count, expectations_not_matched_count,
  response_expectations_matched_count, forward_expectations_matched_count, and llm_chaos_injected_count —
  now additionally publish a proper Prometheus Counter alongside their legacy gauge:
  mock_server_requests_received_total, mock_server_expectations_not_matched_total,
  mock_server_response_expectations_matched_total, mock_server_forward_expectations_matched_total, and
  mock_server_llm_chaos_injected_total. This is non-breaking and additive — the legacy _count gauges are
  retained unchanged so the dashboard UI and existing Grafana dashboards keep working, while PromQL
  rate()/increase() queries can now use the true monotonic _total series (e.g.
  rate(mock_server_requests_received_total[5m])). The new counters are incremented in lock-step with the
  legacy gauges from the same call sites and are mirrored to the OTLP export as observable monotonic counters.

• WASM matcher envelope v2 — query parameters and cookies in match_request. The richer WASM ABI now
  exposes the request's query-string parameters and cookies to a module, so a rule can route on
  ?tenant=acme or a session cookie, not just method/path/headers/body. The JSON envelope passed to
  match_request gained a top-level version field (currently 2) plus queryStringParameters (name to
  array of values) and cookies (name to single value). The change is additive and backward compatible:
  every envelope version is a strict superset of the previous one, so existing version-1 modules (which read
  only method/path/headers/body and ignore unknown fields) keep working unchanged — guarded by a
  WasmRuntimeRequestV2AbiTest that runs the version-1 example module against a version-2 envelope. The
  mockserver-wasm-sdk Rust authoring crate gains req.query_param(...), req.cookie(...) and
  req.version() accessors (returning None against an older envelope), and a new
  examples/wasm/rust-request-v2/ sample module (with prebuilt .wasm) demonstrates query-parameter and
  cookie routing. The POST /mockserver/wasm/test endpoint accepts queryStringParameters and cookies in
  the sample request. See docs/code/wasm-rules.md.

• Test a WASM rule from the editor extensions. The VS Code and JetBrains MockServer extensions can now
  call POST /mockserver/wasm/test to check what a WASM module does against a sample request without
  uploading it or creating an expectation, complementing the existing WASM module upload/list wiring.

• Deterministic embeddings are now semantically plausible, so offline RAG-retrieval tests can rank. A mocked
  embeddings response with deterministicFromInput: true previously produced a hash-seeded uniform-random unit
  vector, so cosine similarity between related texts was meaningless — you could not test vector-search / RAG
  ranking against a mock. MockServer now builds the deterministic vector by n-gram feature hashing: the input
  is tokenised (Unicode-aware, lowercased) into word unigrams, word bigrams, and character 3-grams; each feature
  is hashed (seeded FNV-1a) into a bucket with a signed, sublinear-TF-weighted contribution; the result is
  L2-normalised. Texts that share vocabulary now have a higher cosine similarity (paraphrases ~0.3–0.6) while
  unrelated texts stay near-orthogonal (~0.0–0.1) — e.g. "the cat sat on the mat" ranks far above
  "quarterly financial report" against "a cat sits on a mat" — so retrieval code can rank related documents
  offline with no real embedding model. The vector stays deterministic for the same input, seed, and
  dimensions and unit-length (feature-less input falls back to a seeded non-zero vector); the
  dimensions/seed parameters, provider JSON envelopes, and the non-deterministic (default) random path are
  unchanged.

• Authenticated cross-node cluster verify/retrieve fan-in. The opt-in cluster fan-in
  (clusterVerifyFanIn) now works on a cluster with control-plane authentication enabled. A new
  clusterFanInPeerAuthToken property (env MOCKSERVER_CLUSTER_FAN_IN_PEER_AUTH_TOKEN, default empty)
  gives the peer accessor (HttpClusterPeerAccessor) a credential to present on every cross-node query:
  when set, it is sent verbatim as the control-plane Authorization header (include the scheme, e.g.
  Bearer <jwt>), so peers accept the fan-in query instead of rejecting it with 401/403. All nodes must
  share the same token. With no token (the default) no credential is sent — unchanged, non-breaking
  behaviour; fan-in remains off by default. The property is wired through the config trio
  (ConfigurationProperties/Configuration/ConfigurationDTO) and is covered by the reflective DTO
  round-trip drift guard. The programmatic retrieve(REQUESTS/REQUEST_RESPONSES) path that backs
  dashboard export / one-shot traffic queries already fans in when enabled (verified with a test). Still
  node-local by design (documented, no shared clock across nodes): verifySequence cross-node ordering,
  the live dashboard WebSocket log-view stream, rate-limit / chaos-quota counters, and mTLS
  client-certificate peer authentication. See docs/code/clustered-state.md.

• Startup warm-up removes first-request latency — new startupWarmup property (default on). The very
  first request handled by a freshly started MockServer was a few hundred milliseconds slower than every
  request after it because the request-handling path (Netty HTTP codec, JSON serialisation, response writers)
  only loads and initialises on first use — a cost paid by every readiness poll, including Testcontainers wait
  strategies. MockServer now sends itself a single background PUT /mockserver/status loopback request
  immediately after the ports bind, so that one-off cost is paid off the start-up thread and the first real
  request is fast. The warm-up never delays port binding, is fail-soft (any failure is ignored and logged only
  at TRACE), and uses a control-plane endpoint that creates no recorded requests or log events, so it never
  pollutes verify/retrieve. Disable with -Dmockserver.startupWarmup=false /
  MOCKSERVER_STARTUP_WARMUP=false (e.g. in a locked-down environment where MockServer must not connect to
  itself).

• MCP spec 2025-06-18 negotiation with structured tool output and resource links. MockServer's MCP
  server (McpRequestProcessor) now advertises and negotiates the 2025-06-18 MCP revision while staying
  backward compatible: a client that requests 2025-06-18 gets it, clients still on 2025-03-26/2024-11-05
  keep getting their requested revision (echoed back), and an unknown/omitted version falls back to the latest
  2025-06-18 (negotiateProtocolVersion, stored per-McpSession). For sessions that negotiated 2025-06-18+,
  tools/call results additionally carry structuredContent (the machine-readable tool-result object)
  alongside the existing text block; older sessions are unchanged. The Java McpMockBuilder gains
  withOutputSchema(...) (advertised in tools/list), respondingWithStructured(text, structuredJson)
  (emits structuredContent), and respondingWithResourceLink(uri, name, description, mimeType) (emits a
  resource_link content item), and now defaults protocolVersion to 2025-06-18. The McpContractTest
  conformance tester defaults to 2025-06-18, records the server's negotiated version, and validates the new
  structuredContent/resource_link shapes when present (optional — older servers still pass). Mcp-Session-Id
  emission/handling was already in place. Elicitation (elicitation/create) and the GET SSE server-push stream
  are not mocked (they require a server→client channel MockServer's request/response model does not have); JSON-RPC
  batching remains accepted for back-compat. No MCP tools were added or reclassified.

• Expectation-authoring and record/replay control tools on the MCP server. An AI coding agent
  (Claude Code, Cursor, etc.) can now stand up and drive mocks entirely through the MCP server at
  /mockserver/mcp, closing the "AI agents can only read, not author" gap. Three new tools are added,
  each delegating to the existing HttpState control-plane operation (no logic fork):
  list_expectations (READ — active expectations, optionally filtered by method/path;
  PUT /retrieve?type=ACTIVE_EXPECTATIONS), set_operating_mode (MUTATE — switch SIMULATE/SPY/CAPTURE;
  PUT /mockserver/mode), and promote_recordings (MUTATE — turn recorded traffic into active mocks with
  redaction/consolidation/parameterization; PUT /mockserver/recordings/promote). Each tool is classified
  read-vs-mutate so the control-plane authorization gate applies — a MUTATE tool requires the MUTATE role
  when controlPlaneAuthorizationEnabled is on. The pre-existing authoring/read tools (create_expectation,
  raw_expectation, clear_expectations, verify_request, retrieve_recorded_requests,
  retrieve_request_responses) are unchanged; the /mockserver/mode and /mockserver/recordings/promote
  REST handlers were refactored onto new shared HttpState.setMode(...) / HttpState.promoteRecordings(...)
  methods so REST and MCP share one code path.

• OpenAI Responses API server-side state — previous_response_id chaining, store, and
  GET /v1/responses/{id}. MockServer's Responses API mock (OPENAI_RESPONSES) is no longer stateless:
  each issued POST /v1/responses response is recorded (by default; honours the request's store flag) in a
  new process-wide OpenAiResponsesStore, so agents that chain turns via previous_response_id — sending only
  the new turn plus the prior response id — now run against the mock. OpenAiResponsesCodec.decode prepends the
  stored prior conversation when a request carries a previous_response_id, so conversation matchers and usage
  inference see the full dialogue, and GET /v1/responses/{id} returns the stored response body. The store is
  bounded (LRU), cleared on server reset, and fully back-compatible — a request with no previous_response_id
  and the default store:true behaves exactly as before (it only additionally records the response).

• OpenAI-compatible provider aliases: Mistral, xAI (Grok), DeepSeek, Groq, and OpenRouter. Five new
  Provider values whose codecs and runtime clients delegate to the OpenAI Chat Completions implementations
  (exactly as AZURE_OPENAI does), distinguished by host (api.mistral.ai, api.x.ai, api.deepseek.com,
  api.groq.com, openrouter.ai) in both LlmProviderSniffer and ProviderDetector. Proxy observability now
  classifies traffic to these gateways as LLM (with provider-correct GenAI spans and cost metrics) instead of
  dropping it as non-LLM. Approximate, clearly-flagged pricing rows were added for each in LlmPricing
  (OpenRouter routes vendor-prefixed model ids such as openai/gpt-4o to the underlying vendor's table).

• Chaos experiment composition: recurring runs, staged TCP/lifecycle faults, steady-state pre-check, and
  history. The ChaosExperimentOrchestrator now composes fault primitives beyond a single one-shot HTTP run,
  all as new optional fields that default to the previous behaviour:
  (1) Recurring cron experiments — set "recurring": true alongside a cronSchedule and, after each clean
  completion, the experiment records the run and re-arms itself for the next cron occurrence (e.g. a
  "nightly-error-storm" on "0 2 * * *") instead of going terminal after one run; a stop, auto-halt, or SLO
  breach still ends it for good.
  (2) Staged TCP / connection-lifecycle faults — a stage may carry a tcpProfiles map (host →
  TcpChaosProfile) applied/reset with the same discipline as HTTP profiles, so transport-level faults
  (RST, GOAWAY, latency, bandwidth, preemption) get the same auto-halt and stage progression; a stage is valid
  with HTTP profiles, TCP profiles, or both.
  (3) Steady-state baseline pre-check — with an sloCriteria, an optional baselineWindowMillis evaluates
  the SLO over the pre-experiment lookback window before applying stage 0 and refuses to start
  (aborted_baseline_unhealthy, verdict attached) if the steady state does not already hold, instead of running
  and blaming the experiment.
  (4) Bounded experiment history — every terminal transition (including each recurring run and a
  baseline-refused start) is appended to a bounded ring (last 50, newest first) exposed at
  GET /mockserver/chaosExperiment/history for recurring-run trails and CI trend dashboards. The new
  recurring, tcpProfiles, and baselineWindowMillis fields round-trip through the experiment definition JSON.

• Typed mock-drift client methods across all 8 client libraries. Each client now exposes a typed wrapper
  for the drift-detection control plane — retrieveDrift() (GET /mockserver/drift, returns the parsed
  { count, drifts } report) and clearDrift() (PUT /mockserver/drift/clear) — so programmatic users no
  longer have to hand-roll raw HTTP. Added to the Java (retrieveDrift/clearDrift), Node
  (retrieveDrift/clearDrift), Python (retrieve_drift/clear_drift), Ruby (retrieve_drift/clear_drift),
  Go (RetrieveDrift/ClearDrift), .NET (RetrieveDrift/ClearDrift + async variants), Rust
  (retrieve_drift/clear_drift) and PHP (retrieveDrift/clearDrift) clients, each following that client's
  existing control-plane conventions, with mocked-transport unit tests. The drift-detection documentation now
  shows client-library tabs alongside the REST examples.

• Experimental JDK 25 AOT-cache Docker image variant (Project Leyden) for ~2x faster container startup.
  New docker/aot/Dockerfile builds a MockServer image on a jlink-trimmed Temurin 25 runtime with an
  ahead-of-time cache (JEP 483/514) baked in via a training run at image build time. Measured time-to-ready
  roughly halves versus the standard image (~0.35 s vs ~0.7–0.8 s from docker run to a 200 from
  PUT /mockserver/status) with identical behaviour — it is the real HotSpot JVM, so 100% feature parity.
  Published from this release as opt-in X.Y.Z-aot / latest-aot tags (Docker Hub + ECR Public),
  error-isolated in the release pipeline like the clustered image, and selectable from the MockServer
  Testcontainers module via new MockServerContainer(MockServerContainer.aotImage()). The Testcontainers
  documentation now explains the fast-test hierarchy (suite-scoped container + reset(), in-process
  MockServer for Java tests) and the runtime-level options evaluated (AppCDS, AOT cache, GraalVM native
  image) with measured figures and the reasons native-image is not supported. (relates to #​2385)

• Mock-drift detection master switch and sampling. New driftDetectionEnabled (boolean, default true) turns
  mock-drift analysis of forwarded responses on or off, and driftSampleRate (double 0.0–1.0, default 1.0)
  analyses only a sampled fraction of forwarded responses. Both defaults preserve the previous always-on behaviour;
  set driftDetectionEnabled=false (or lower driftSampleRate) to cut the per-forward overhead when proxying at
  high volume.
