What JasperFx/marten shipped

Marten 9.58.0 is out on JasperFx 2.100.0 and Weasel 9.49.0, with per-tenant composite rebuilds fixed. Also this week: DCB tag queries skip archived events, repeated Async fetches stop double-applying events, and cursor paging handles nullable and value type keys.

Marten 9.58.0 shipped this week, moving to JasperFx 2.100.0 and Weasel 9.49.0 and making per-tenant composite rebuilds work on per-tenant partitioned stores. Alongside it, several correctness fixes landed: DCB tag queries now exclude archived events, a repeated Async-lifecycle fetch no longer folds events onto the same document twice, and a per-tenant rebuild resets each composite member's progression. Cursor paging now handles nullable leading sort keys and strong-typed id keys, a stream that folds to null keeps its history, and a custom IMartenLogger no longer silences logging. EventStoreUsage also reports the event store's TenancyStyle.

Marten 9.56.0 is out. Raw event queries now support IQueryable through IReadOnlyEventStore.QueryRawEvents. Also in this week: culture-invariant document aliases and DDL names, HiLo factory failures no longer cached across an outage, and projection version tokens move on every wri

Marten 9.56.0 shipped this week. IReadOnlyEventStore.QueryRawEvents now supports IQueryable, with tenant rules matching the other event store queries. Fixes landed for culture-dependent identifiers: document aliases, DDL template lookups and flat-table upsert function names now use invariant culture, which matters under Turkish and Azerbaijani cultures when names contain an uppercase I. A failed HiLo factory build is no longer cached across an outage, so sequence generation recovers when the database returns. Subclass queries resolve nested duplicated fields to their columns, verbose tracing now emits marten.append.event on the Quick append routes, and the diagnostics writer moves a projection document's version token on every write.

Marten 9.51 through 9.54 shipped this week: UndeleteDocumentAsync and QueryEventData<T>, tenant removal fixes under per-tenant partitioning, false ConcurrencyException fixes, Contains() with array literals in LINQ, and a cancelled save no longer left idle in transaction.

This week Marten shipped releases 9.51 through 9.54. UndeleteDocumentAsync restores a soft-deleted document, and QueryEventData<T> adds store-agnostic LINQ over event bodies, along with metadata ordering and projection start floors behind SubscribeFromFirstRun. Multi-tenant setups got several fixes: removing a tenant now clears its natural-key and DCB tag rows before the partition drop, and compacting streams with DCB tags works again. UndoDeleteWhere and HardDeleteWhere no longer raise a false ConcurrencyException, an inline array literal works in LINQ Contains(), and a save cancelled before COMMIT now rolls back instead of sitting idle in transaction.

Marten 9.50.3 is out: Native AOT, hard stream delete via TombstoneStream, two schema-naming fixes and three behavior changes to check before upgrading. Also this week: TotalResults now counts matches, and Include() joins on the document's own id no longer fail.

Marten 9.50.3 is out. It adds Native AOT support and hard stream delete through TombstoneStream, along with two schema-naming fixes that could not be worked around and three behavior changes worth reading before you upgrade. The rest of the week was mostly correctness: Stats() with Include(), Select() and Take() now returns the number of matches instead of the page size, and Include() joined on the queried document's own id no longer fails with a missing column error. A few queries that always returned nothing now skip the database entirely, and a custom foreign key name is kept under conjoined tenancy.

Marten 9.49.0 makes LINQ projections work under Native AOT. 9.48.0 adds document diagnostics filtering and ordering. Also fixed repeated keyset pages with NodaTime sort keys, grouped Count with a predicate, and async fetch consistency gaps.

Marten shipped several releases this week. 9.49.0 makes LINQ projections into new objects and structs work under Native AOT, with projection select clauses resolved without runtime code generation. 9.48.0 lets IDocumentStoreDiagnostics.QueryDocumentsAsync apply Where, OrderBy and Arguments. We also fixed keyset cursor paging repeating the first page when a sort key is a NodaTime type, Count and LongCount with a predicate inside grouped projections, a quick-mode StartStream collision throwing a raw duplicate key error, and async fetches whose snapshot and delta reads disagree returning a null or stale aggregate. Inline EF Core projections now use one pooled connection per save and no longer lose their row to a retried commit. 9.47.0 changed FetchForWriting and FetchLatest consistency behavi

Marten 9.46.0: Native AOT resiliency improvements, timeout retry changes, and failure visibility. Five behaviour changes surface issues previously absorbed. See the release notes for details on upgrade impact.

Marten 9.46.0 focuses on resiliency and Native AOT. Command timeouts no longer retry automatically on reads—they now reach application code on first attempt. Strong-typed document IDs work under Native AOT, connection lifetimes track failure states, and the daemon's event loader stops double-retrying. Five behaviour changes worth reviewing if you upgrade.

Marten 9.40.0: tenant id consistency fixes, projection progress row count check, GroupJoin/SelectMany LINQ correction, and Select() null handling. Read the release notes for the archiving behaviour change if you use projections.

Marten 9.40.0 ships this week with fixes across tenancy, projections, and LINQ queries. Tenant id handling is now consistent at all boundaries where ids are stamped or keyed. Projection progress tracking checks every write instead of just the first. GroupJoin().SelectMany() outer projections work correctly. Select() projections no longer embed explicit JSON nulls for absent keys. The README is updated for current contributor workflows. One behaviour change: archiving projections now decides one action per batch rather than per event.

Marten 9.37.0: fixed eighteen silent correctness bugs in vector and hybrid search found by auditing the surface 9.36.0 shipped. Searches returned wrong rows in plausible order. All fixed.

Marten 9.37.0 shipped this week with eighteen correctness fixes for vector and hybrid search. Every bug was silent—searches returned plausible answers in the right order, but they were wrong. The 9.36.0 release introduced PgVector search; 9.37.0 audited the entire surface and fixed what it found. Marten.PgVector now shares JasperFx's store-neutral vector contracts, aligning with other stores on one API.
