chore: Bump Marten from 8.37.1 to 9.2.0

[dependabot]

Updated Marten from 8.37.1 to 9.2.0.

Release notes

Sourced from Marten's releases.

9.2.0

Marten 9.2.0

Features & changes

• Override IEventStore.AllDatabases() on DocumentStore (#​4570, #​4571). Implements the store-agnostic database accessor added to JasperFx.Events.IEventStore. Delegates straight to ITenancy (mirroring IMartenStorage.AllDatabases()) and projects to IEventDatabase, so store-neutral monitoring/tooling can reach every database to call the read abstractions (AllProjectionProgress, FetchDeadLetterCountsAsync / CountDeadLetterEventsAsync) even when only IEventStore is registered in DI.

Dependencies

• Upgraded all JasperFx.* packages to 2.2.0 (JasperFx, JasperFx.Events, JasperFx.Events.SourceGenerator, JasperFx.SourceGenerator).

Full Changelog: JasperFx/marten@V9.0.2...V9.2.0

9.0.2

Marten 9.0.2

A patch release that fixes #​4557 — self-aggregating projections failing for consumers that reference only the Marten package.

Fixes

• #​4557 — Self-aggregating projections now work out of the box. Marten 9 dispatches conventional Apply/Create/ShouldDelete projection methods through the compile-time JasperFx.Events.SourceGenerator and has no runtime fallback, but the generator shipped as a DevelopmentDependency and never flowed to a consumer that only referenced the Marten package — surfacing as InvalidProjectionException: No source-generated dispatcher found ... at DocumentStore.For(...). Marten now bundles the analyzer in its own NuGet package, so a plain <PackageReference Include="Marten" /> runs the generator automatically. (#​4558)

• Self-aggregating record aggregates work without a Snapshot<T> call site and without partial. Bumped JasperFx.Events / JasperFx.Events.SourceGenerator to 2.1.1 (JasperFx/jasperfx#​367): the generator now emits a self-aggregating evolver for a record from its own declaration (parity with classes), which also fixes the cross-assembly case where the aggregate type is defined in a different assembly than its registration.

• Docs. Corrected the migration guide's projection section, which incorrectly stated Marten falls back to a runtime evolver lookup for non-partial convention projections; documented that self-aggregating Snapshot<T> types do not need to be partial (only projection subclasses do).

Dependency bumps

• JasperFx.Events 2.1.0 → 2.1.1
• JasperFx.Events.SourceGenerator 2.1.0 → 2.1.1

No public API changes from 9.0.1.

9.0.1

Marten 9.0.1

A patch release on the Critter Stack 2026 foundation, rolling up the latest JasperFx 2.0.1 / JasperFx.Events 2.1.0 / Weasel 9.0.1 dependencies along with several source-generator and reliability fixes.

Foundation bumps

• JasperFx 2.0.0 → 2.0.1
• JasperFx.Events / JasperFx.Events.SourceGenerator → 2.1.0
• JasperFx.SourceGeneration → JasperFx.SourceGenerator 2.0.1 (package renamed; #​4555)
• Weasel.Postgresql / Weasel.EntityFrameworkCore 9.0.0 → 9.0.1

Fixes

• Self-aggregating source-generator fixes (via JasperFx.Events 2.1.0, consumed in #​4547):
  • #​4542 — required members on self-aggregating snapshot types no longer break generated evolver construction; default! is emitted only when a public parameterless constructor exists, otherwise RuntimeHelpers.GetUninitializedObject is used.
  • #​4543 — nullable [ReadAggregate] aggregate parameters generate correctly.
• #​4546 — IEventDatabase dead-letter count reads (CountDeadLetterEventsAsync / FetchDeadLetterCountsAsync) are implemented on MartenDatabase via LINQ over the DeadLetterEvent document.
• #​4540 — opt-in System.Text.Json source-generation context support (SystemTextJsonSerializer.UseTypeInfoResolver) for AOT/trimming-friendly metadata.
• #​4552 — intermittent CI flakes fixed: feature_flag_positive advisory-lock contention (distinct ApplyChangesLockId, #​4553) and the conjoined multi-tenant query_before_saving XX000: tuple concurrently updated migration-DDL race (resolved upstream in Weasel 9.0.1 / weasel#​293).

No public API breaking changes from 9.0.0. RestoreV8Defaults() continues to revert the 9.0 default flips.

9.0.0

Marten 9.0.0 — Critter Stack 2026

The headline release of the Critter Stack 2026 wave, on the final JasperFx 2.0 + Weasel 9.0 foundation.

Highlights

• Foundation: JasperFx 2.0.0 / JasperFx.Events 2.0.0 / Weasel 9.0.0 (final). Targets net9.0;net10.0.
• No runtime code generation. Roslyn is gone — JasperFx.RuntimeCompiler is no longer a dependency. Document/event storage is hand-written closed-shape; compiled queries use Marten.SourceGenerator. No codegen write step for Marten.
• Cold-start + AOT: AOT-publishable in Static mode; lazy document-mapping materialization; per-query handler-factory caching.
• Dedupe pillar (jasperfx#​214): IStorageOperation rebased on Weasel.Core; async-daemon distributor concretes consumed from JasperFx.Events.Daemon; OperationRole / BulkInsertMode relocated to Weasel.Core.
• Defaults flipped to best-perf: QuickWithServerTimestamps append mode, advanced async tracking, bigint events, lightweight default sessions, System.Text.Json default — all revertable via RestoreV8Defaults().
• Versioning: IRevisioned.Version stays int (V8-compatible); new ILongVersioned (long) for MultiStreamProjection documents.
• DCB: optional HSTORE tag storage; FetchForWritingByTags<T> for identity-less boundary aggregates.

See the migration guide (docs/migration-guide.md). Master plan: marten#​4349. Ships in lockstep with Polecat 4.0.
