⚠️ Breaking API change: rivermigrate.Migrator.Validate and rivermigrate.Migrator.ValidateTx now take a *rivermigrate.ValidateOpts parameter. Pass nil to preserve previous behavior. We normally endeavor not to make any breaking API changes, but this one will keep the API in a much nicer state, and is on an ancillary function that most installations won't be using. PR #​1259

Added

• Added MetadataSet to stage job metadata updates from worker middleware, HookWorkBegin, workers, or HookWorkEnd, with changes persisted when the job is completed. PR #​1269

Changed

• Add rivermigrate.ValidateOpts.TargetVersion so validation can check migrations up to a specific target version, matching the target-version behavior available on Migrate and MigrateTx. Notably, this is a breaking API change as the validate functions previously didn't take any options. PR #​1259
• When using (*Migrator[TTx]).Migrate with a TargetVersion that's already applied, River now no-ops idempotently instead of returning an error as a user convenience. PR #​1260
• Add logging statement for dropped job and queue subscription events at warn level when a subscriber buffer is full. PR #​1271

Fixed

• Add a 10-second timeout around StandardPilot.JobGetAvailable so a stalled standard-pilot fetch no longer hangs a producer indefinitely. PR #​1255
• Fixed rivertest.Worker.Work and WorkJob to honor a configured custom Config.Schema when transitioning a job to its running state. Previously, the running-state update ran unqualified and could fail on a connection whose search_path didn't include the configured schema. PR #​1262
