Release notes

Sourced from WolverineFx's releases.

6.17.3

Bug-fix and scale release, following the 6.17.2 community sweep. Every item below came from a community report or a review finding — thank you all.

Closed issues

  • #​3375 — durability metrics polling pinned a connection per database per node (PR #​3384 by @​erdtsieck). Each durability agent ran its own in-phase PeriodicTimer, so at high database counts the metrics polling itself became significant connection pressure. Agents now register their store with a node-wide sequential sweeper that walks the node's databases one at a time across the UpdateMetricsPeriod window — at most one metrics connection in flight per node, regardless of database count. The registration set is re-read every pass, so databases join and leave the sweep as agents start and stop without a restart.
  • #​3332 — CIAWS was disabled by a broken SNS per-tenant LocalStack setup (PR #​3364 by @​Steve-XYZ). Test-only; re-enables the AWS CI job. Partially addresses #​3350 (the CIPolecat half remains open).
  • RabbitMQ listeners ghosted after a broker restart on a channel callback exception (PR #​3370 by @​kconfesor). The agent stayed latched after a channel-only shutdown and was never rebuilt, so a listener came back "connected" but dead. Reviewed specifically against the #​3171/#​3187 channel-only-shutdown work to confirm it does not reintroduce the latched-Disconnected state that #​3187 fixed. Two follow-ups are tracked in #​3391.
  • ProductSupport#​33 — CritterWatch telemetry was caught by tracked-session waits (PR #​3390, reported by @​uniquelau). A monitored host publishes telemetry that a TrackedSession would pick up and then sit waiting on messages the test never sent. The default ignore rule now covers all of INotToBeRouted (agent commands and framework telemetry), with a deliberate carve-out for Acknowledgement / FailureAcknowledgement, which the session's own acknowledgement APIs depend on. If you are on an older version, IgnoreMessagesMatchingType(t => t.CanBeCastTo<INotToBeRouted>()) is the workaround.

Fixes from review

  • Metrics sweeper: unregistration race and a hot-spin guard (PR #​3393, follow-ups from the #​3384 post-merge review). The sweeper removed a registration by URI alone, so when an agent for a database stopped after a replacement agent for the same database had registered — exactly what agent redistribution does — the stopping agent evicted the live registration, and that database silently stopped being polled until the node restarted. Unregistration now removes only the exact registration instance it created. Separately, UpdateMetricsPeriod = TimeSpan.Zero would hot-spin the sweep loop (the pre-#​3384 PeriodicTimer threw); it is now rejected at configuration time, with DurabilityMetricsEnabled = false as the way to turn polling off.

Marten test-helper: PauseThenCatchUpOnMartenDaemonActivity

  • #​3388 — cold first catch-up appeared to stall (PR #​3394, reported by @​uniquelau). Investigated in depth. The reported mechanism — that coordinator.ResumeAsync() does not start never-started shards — does not hold: under Wolverine-managed distribution the coordinator is WolverineProjectionCoordinator, whose ResumeAsync builds the daemon lazily and starts every shard, bypassing agent assignment entirely. The cold path works, and there are now four tests proving it (including with a second subscription-agent consumer sharing the agent family).

    The real defect was a timeout mismatch, and it explains the reported symptom exactly. The stage runs inside a child TrackedSession whose token cancels at TrackedSession.Timeout — 5 seconds by default — while the catch-up ignored that token and waited on an internal 60-second budget. The session gave up first and left the catch-up envelope started-but-never-finished, which reads as a hang. This is a genuine 6.16 → 6.17 behavior change: the old active ForceAll finished inside 5 seconds; resume-and-wait on a cold daemon or a busy machine does not. The catch-up now honors the session's token and raises an actionable TimeoutException naming the store and pointing at TrackActivity().Timeout(...).

    If you hit this on 6.17.0–6.17.2, raising the tracked-session timeout is the fix.

Docs

  • New page: gRPC + Sagas (PR #​3389, following @​erikshafer's coverage in PR #​3386). gRPC services can start and continue sagas with no gRPC-specific code — the saga identity must be on the message body, because a gRPC method is a thin shim in front of IMessageBus.InvokeAsync<T> and the chain that runs is the handler's. The header-identified gap is tracked as #​3385, with a clear diagnostic planned.
  • Testing guide (PR #​3395): tracked sessions ignore framework telemetry by default as of this release, and — the trap behind #​3388 — Timeout() bounds the whole session including its stages, so a slow stage like PauseThenCatchUpOnMartenDaemonActivity() is capped by the session's 5-second default, not by any budget internal to the stage.

6.17.2

Community-issue sweep release. Every fix below shipped same-day from issues filed by the community — thank you all.

Closed issues

  • #​3371 — any ApiExplorer read before server start permanently emptied every OpenAPI document (PR #​3373 by @​uniquelau). WolverineApiDescriptionProvider now enumerates the HttpGraph (complete when MapWolverineEndpoints() returns) instead of the start-time EndpointDataSource, so ASP.NET's version-keyed cache can never freeze an empty first read. If you monitor Wolverine hosts with CritterWatch and expose OpenAPI, upgrade to this release (see JasperFx/CritterWatch#​689).
  • #​3374 — [AsParameters] + compound-handler LoadAsync binding the same route variable generated uncompilable code (CS0136/CS0841, host failed at startup) (PR #​3381). Binding frames are now emitted once per chain and re-homed so any second consumer reuses them; both the [FromRoute] and [AsParameters]-parameter variants are covered. The related OpenAPI gap (route params bound only by LoadAsync missing from the operation) is tracked as #​3380.
  • #​3372 — [AsParameters] query binder silently ignored unparseable values (PR #​3379). New opt-in WolverineHttpOptions.RejectUnparseableQueryValues: a present-but-unparseable query value short-circuits with a 400 ProblemDetails naming the parameter, matching ASP.NET minimal APIs; missing values keep their initializer in both modes. The default flips to strict in Wolverine 7.0.
  • #​3368 — gRPC server-side tenant-id detection (PRs #​3369 by @​erikshafer + #​3382). The server now reads back what the client interceptor stamps: envelope propagation onto the scoped IMessageContext, plus a full ITenantDetectionPolicies-style mirror (opts.TenantId.IsRequestHeaderValue(...), IsClaimTypeNamed(...), DetectWith<T>()) that sets the codegen tenant variable Marten/Polecat session frames consume — with a zero-config default when the client stamps tenant-id. New docs page: gRPC multi-tenancy.
  • #​3375 (docs half) — documented DurabilityMetricsEnabled = false and raising UpdateMetricsPeriod as mitigations for metrics-polling connection load at high tenant-database counts (PR #​3378). The per-node sweeper implementation is in progress on the issue.

Dependency bumps

  • Marten 9.15.0 (sharded-tenancy provisioning repair, marten#​4942) and JasperFx 2.27.0 (daemon block observability, jasperfx#​506/#​507) — the fixes from the marten#​4941 silent-outage incident (PR #​3383).

6.17.1

Wolverine 6.17.1 is a bug-fix release covering EF Core outbox enlistment gaps in Wolverine.Http, persistence provider resolution, HTTP route parameter binding, multi-tenancy message store roles, and a RavenDB startup race. It also upgrades the Marten dependency to 9.14.1.

EF Core & persistence

  • HTTP endpoints that inject a DbContext and cascade messages only through a tuple return are now enlisted in the EF Core outbox, so cascaded messages are no longer sent before the transaction commits when using Lightweight mode (#​3358, #​3362)
  • Wolverine.Http endpoints that persist entities through storage actions (IStorageAction<T> / storage side effects) are likewise enlisted in the EF Core outbox in Lightweight mode (#​3353, #​3357)
  • When both EF Core and Marten (or another catch-all provider like RavenDb) are registered, the selective EF Core persistence provider is now evaluated first regardless of registration order, so DbContext-based handlers get the correct transactional middleware (#​3359, #​3361)
  • MessageStoreRole.Ancillary is now honored for tenanted message stores (static tenants and master-table tenancy) instead of silently reporting Main (#​3351), with the registration behavior now covered by tests across PostgreSQL, SQL Server, SQLite, MySQL, and Oracle

HTTP

  • [FromRoute(Name = "...")] is now honored on plain endpoint method parameters (previously only inside [AsParameters] types), enabling route segments like {journey-id} that aren't valid C# identifiers (#​3356 — thanks to @​outofrange-consulting!)

RavenDB

  • Fixed a node sequence startup race that could cause duplicate node assignments when multiple nodes started concurrently (#​3352)

Dependencies

  • Marten upgraded to 9.14.1, which brings a substantial round of LINQ query-translation improvements plus event-store partitioning, high-water, and AoT fixes (#​3363)

Documentation

  • Corrected the HTTP QUERY verb documentation: transactional middleware is applied based on a chain's dependencies (e.g. taking an IDocumentSession or DbContext), not the HTTP verb (#​3355, #​3360)

6.17.0

Why is this such a big release? Because @​jeremydmiller went on a 3 night vacation and the community decided to throw in issues and pull requests left and right!

A big theme was filling in the remaining gaps of "Name Broker" and "Broker per Tenant" support in every external messaging transport where it made sense to add that rather than just being Rabbit MQ, Azure Service Bus, and hit and miss everywhere else. We also added HTTP QUERY support.

What's Changed

Full Changelog: JasperFx/wolverine@V6.13.1...V6.14.0

6.13.1

Patch release on the 6.x line — a Critter Stack dependency refresh plus one targeted fix. No breaking changes.

🐛 Fixes

  • DLQ admin readers tolerate a NULL received_at (#​3165) — the dead-letter explorer could report 0 messages even when dead letters existed; the RDBMS DLQ readers now handle a null received_at column.

⬆️ Dependencies

Full Changelog: JasperFx/wolverine@V6.13.0...V6.13.1

6.13.0

Wolverine 6.13.0 on the 6.0 line (JasperFx 2.x, net9.0/net10.0). The headline is a top-to-bottom Kafka integration re-evaluation (epic #​3134) that makes the transport idiomatic and high-throughput, plus [AsParameters] HTTP fidelity fixes and event-subscription/projection-distribution hardening. No breaking changes.

🚀 Kafka integration re-evaluation (#​3134)

  • Commit-strategy overhaul with CommitMode (#​3152) — StoreThenAutoFlush (default, non-blocking idiomatic throughput), PerMessage, and CommitOffsetsAfterCount/AfterInterval batch modes.
  • In-flight-safe offset watermark across all commit strategies (#​3162) — under concurrent out-of-order completion the committed/stored position never advances past a still-in-flight message; tolerates compacted/read_committed offset gaps.
  • Scale-out & concurrency — cooperative-sticky rebalancing + static membership (#​3154), and opt-in intra-partition concurrency by key with ordered-per-key guarantees via the durable inbox (#​3158).
  • Cold start vs. live tail — first-class AutoOffsetReset and ephemeral hot-tail / broadcast consume (#​3155).
  • Bounded one-shot topic replay by offset/timestamp via Assign (#​3156).
  • Idempotency & exactly-once — idempotent producer + read_committed isolation, with EOS guidance (#​3157).
  • Non-blocking tiered retry topics via the OnException<T>().MoveToKafkaRetryTopic(...) DSL (#​3160).
  • Fix: ExtendConsumerConfiguration now preserves parent/global consumer settings (#​3151).

🌐 HTTP — [AsParameters] (#​3135)

  • OpenAPI route-type fidelity + multiple-body guard (#​3141)
  • Optional [FromBody] in [AsParameters]: binds null with required:false (#​3142)
  • Fix [AsParameters] + [FromBody] + [WriteAggregate] codegen 500 (#​3143/#​3144)
  • Docs: [AsParameters] as the idiomatic route/body split (#​3145)

🗄️ Event subscriptions, projections & distribution

  • Lift event-subscription distribution into core; fix Polecat managed distribution (#​3136, closes #​3133)
  • Rebuild a registered projection with no live agent — Inline/Live/undistributed (#​3163)
  • Fix: SQL Server node-capabilities delimiter must be newline, not comma — Polecat managed-distribution startup crash (#​3164)

🐛 Other fixes

  • Fix circuit breaker (#​3132) and RabbitMQ post-#​3132 cleanup (#​3138)

🐛 Bug Fixes / Codegen

#​2963 (closes #​2958): EF Core transaction middleware + post-save cascade flush

The HTTP-handler codegen path under the EF Core transaction middleware + outbox cascade (GH-536) no longer fails handler compilation. Two related codegen issues addressed in this PR:

  • CS0128 duplicate var messageContext declaration in the generated handler. Cherry-picked from #​2959, originally authored by @​kentcooper — credit preserved on commit 9df45bfde. Root cause: MessageBusSource was returning a fresh CreateMessageContextWithMaybeTenantFrame per call; once cached + always returning the concrete MessageContext, the duplicate goes away.
  • CS1061 'IMessageContext' does not contain a definition for EnqueueCascadingAsync — surfaced after the cache fix because once the source produced a concrete MessageContext Variable, the downstream CaptureCascadingMessages frame still declared its MethodCall target as typeof(IMessageContext) and emitted a bad ((IMessageContext)messageContext).EnqueueCascadingAsync(…) cast. Fixed by re-targeting CaptureCascadingMessages to the concrete MessageContext type — mirrors the existing FlushOutgoingMessages pattern. Latent in src/Wolverine/Runtime/Handlers/CaptureCascadingMessages.cs since 020e79013e (2022-09-16); the variable-cache fix is what flipped it from masked to visible.

📦 Dependency bumps

  • JasperFx + JasperFx.Events + JasperFx.Events.SourceGenerator + JasperFx.SourceGenerator 2.2.1 → 2.2.3
  • JasperFx.RuntimeCompiler unchanged (own 5.x line, stays at 5.0.0)
  • Marten / Polecat unchanged (9.2.0 / 4.2.1)

Upstream JasperFx 2.2.2 release: https://github.com/JasperFx/jasperfx/releases/tag/V2.2.2 (Fix source-created codegen variable reuse, #​392). 2.2.3 was a same-day version-bump-only re-roll.

📖 Documentation

  • #​2960 (@​outofrange-consulting): clarify the JasperFx command-line integration link in the diagnostics docs.
  • #​2964 (closes #​2962): re-align the dead-letter REST API reference with the current DeadLetterEnvelopeGetRequest / DeadLetterEnvelopeResults / DeadLetterEnvelopeIdsRequest signatures — the docs still described the pre-5 cursor-based pagination (StartId/NextId) and the legacy DeadLetterEnvelopesFoundResponse wrapper. Updated for offset-based PageNumber pagination, the multi-store IReadOnlyList<DeadLetterEnvelopeResults> response shape, and tenant-aware Ids request bodies.

🧪 Known issues

  • #​2965: SharedMemory transport does not serialize envelopes on cross-host send. Surfaces as a MartenTests.Distribution.with_ancillary_stores.spread_out_over_multiple_hosts failure where AssignAgent system commands arrive at the destination node with empty Data/MessageType and the receive pipeline can't deserialize them. Long-standing — the marten CI workflow has been red on this test through V6.2.0 and V6.2.1, predates this release line entirely. Unblocked the V6.2.2 cycle by adding [Fact(Skip = "…")] referencing #​2965; the underlying serialization bug is tracked separately and is out of scope for a JasperFx pin-bump patch release.

6.2.0

Bug-fix + feature release on top of 6.1.0 — 13 PRs.

✨ New features

Custom Result<T> Support — #​2952 (refs #​2221)

First three phases of native Result<T>-style handler return-value support: ResultPolicy registry, handler-side unwrapping seams, and caller-side InvokeAsync<T> unwrap. Lays the groundwork for integrating with libraries like ErrorOr, OneOf, FluentResults, etc.

DbContext Abstractions for EF Core Transaction Middleware — #​2919, #​2954

The EF Core transaction middleware now binds correctly when handler parameters are declared as interface or abstract base abstractions over a concrete DbContext. Multiple abstractions to the same DbContext are supported in a single handler — the runtime resolves them all to the same scoped instance, and the transaction still auto-applies.

📖 DbContext Abstractions docs

🚀 Performance

Outgoing Envelope Pooling — #​2956 (closes #​2955)

MessageRouter.RouteForPublish now acquires from the runtime envelope pool (originally introduced in #​2741 for the Executor sites in 6.1.0) when the route's sender is an InlineSendingAgent or BufferedSendingAgent. Measured −504 B/op (−90 %) on the transport-bound publish/send paths in the CritterStackScalability harness, with ~10× fewer Gen0 collections per 1k ops. DurableSendingAgent, local-queue agents, and ISenderRequiresCallback senders are explicitly excluded — different lifecycle plumbing required, tracked as follow-ups.

🐛 Bug fixes

  • #​2943 Fix scheduled-cascade loss from [ReadAggregate] / [DocumentExists] handlers (closes #​2941).
  • #​2948 Pre-populate chain.AncillaryStoreType in Phase A so the inbox-routing map sees [MartenStore] (closes #​2944).
  • #​2947 Bump Polecat 4.1.1 → 4.2.1 and unskip the three Polecat scheduled-cascade tests.

Persistence (Postgres / MySQL)

6.1.0

Wolverine 6.1.0

Minor release. Critter Stack dependency refresh, plus the rollup of the entire post-6.0.0 6.0.x line — most significantly the AOT runtime-scanning-elimination work and a new command-line handler-discovery diagnostic.

ℹ️ There was no standalone 6.0.1 tag/GitHub release (it shipped as a NuGet version only), so the changelog below covers every PR merged since 6.0.0 — which includes everything released as 6.0.1 through 6.0.3.

Dependencies

  • Marten / Marten.AspNetCore / Marten.Newtonsoft: 9.0.1 → 9.2.0
  • JasperFx.* (non-RuntimeCompiler): 2.1.3 → 2.2.0 (#​2938)
  • Polecat: 4.1.1 (unchanged — already latest)
  • JasperFx.RuntimeCompiler: 5.0.0 (unchanged — own 5.x line)

Marten 9.2.0 now bundles JasperFx.Events.SourceGenerator as an analyzer, so projects referencing Wolverine.Marten receive it transitively. The previously-explicit analyzer references were dropped from the 8 Marten-referencing projects to avoid running the generator twice, which produced duplicate Evolve/*Evolver build errors (#​2939). PolecatTests retains its explicit reference because Polecat does not bundle the generator.

New & Noteworthy

AOT: eliminate runtime assembly scanning — AOT Publishing. Static-mode apps no longer scan assemblies at startup; discovery now flows through source-generated manifests:

  • Handlers + message types — #​2906 / #​2928
  • HTTP endpoints — #​2925 / #​2929
  • gRPC services (incl. the direct-mapped mode) — #​2926 / #​2930 / #​2934
  • [WolverineHandlerModule] assemblies, with no filesystem probe — #​2905 / #​2935
  • Extension discovery manifest — #​2902 / #​2918
  • Remaining ad-hoc discovery scans routed through JasperFx TypeQuery — #​2909 / #​2932
  • Generated HTTP/gRPC types attached by full name instead of a GetTypes() scan — #​2908 / #​2936

Command-line handler-discovery diagnostic — Command Line Integration · Command Line Diagnostics tutorial. New dotnet run -- wolverine-diagnostics describe-handlers <Type> runs DescribeHandlerMatch from the CLI so you can troubleshoot handler discovery without editing your bootstrapping code — #​2921 / #​2923

Build-time OpenAPI generation — Command Line Integration. dotnet run -- openapi generates the OpenAPI document without starting the host (no database/broker required) — #​2903 / #​2911

SQS fair queues on standard queues — support MessageGroupId on standard Amazon SQS queues — #​2886 / #​2889

SignalR ClaimsPrincipal — the connection's ClaimsPrincipal is now exposed on SignalREnvelope — #​2927 / #​2937

EF Core transactional outbox timing fix — the EF Core transaction and outbox flush now complete before the HTTP response is written — #​2917 / #​2920

Mixed-lifetime IEnumerable<T> support; Lamar removed — handlers depending on a mixed singleton/scoped IEnumerable<T> now resolve every element correctly; Lamar is no longer used or supported, and the built-in ServiceProvider is the container — #​2896 / #​2914

Aggregate handler naming clarity — clarified and guarded the *AggregateHandler naming convention vs. [ReadAggregate] — #​2924

Production code-generation guidance — Code Generation. How to drop Roslyn from production images, with a linked CqrsMinimalApi sample — #​2900 / #​2912

Bug fixes

  • Ancillary store outbox schema for projection side effects — #​2887 / #​2888
  • NRE from null-Sender routes built during description mode — #​2897 / #​2899

The messaging/orchestration release completing the Critter Stack 2026 wave, on the final foundation (JasperFx 2.0 / Weasel 9.0 / Marten 9.0 / Polecat 4.0).

Highlights

  • Foundation (final): JasperFx 2.0.0 / JasperFx.RuntimeCompiler 5.0.0 / Marten 9.0.0 / Polecat 4.0.0 / Weasel 9.0.0. Targets net9.0;net10.0.
  • Runtime codegen decoupled from core (BREAKING): WolverineFx no longer ships Roslyn. Apps in the default TypeLoadMode.Dynamic must add WolverineFx.RuntimeCompilation, or pre-generate via codegen write + TypeLoadMode.Static (the trimmer then drops Roslyn). See the migration guide.
  • ServiceLocationPolicy.NotAllowed is the default (BREAKING) — restructure registrations, allow-list per type, or call opts.RestoreV5Defaults() to revert.
  • AOT-clean (pillar #​213): every packaged library carries IsAotCompatible=true (except the intentional WolverineFx.RuntimeCompilation); Static-mode publish drops Roslyn.
  • Cold-start (pillar #​212): Tier-1 pre-generated static handler registry skips handler-discovery scanning in Static mode.
  • Newtonsoft extracted to WolverineFx.Newtonsoft / WolverineFx.Http.Newtonsoft; IForwardsTo<T> discovery now explicit; removed [Obsolete] APIs (EventForwardingToWolverine, RedisTransport.BuildRedisStreamUri, PulsarEndpoint.UriFor).

Migration guide: https://wolverinefx.net/guide/migration.html (or docs/guide/migration.md). Master plan: wolverine#​2715. Remaining release-cut comms items tracked in #​2745.
