Changelog
Every release since 2.8. Versions follow semver; anything under Changed may need a line of your attention.
v2.14.0
v2.13.2
Lease renewal during long GC pauses
- Fixed
- Workers on Node 22 could lose a lease during a stop-the-world pause over 4 s. Renewal now runs on a separate timer thread.
v2.13.0
Go SDK: typed step results
- Added
- Changed
- sp.Run is generic over its return type; no more interface{} casts.
- sp.RunAny kept for one release, then removed in 3.0.
v2.12.0
Event history export
- Added
- Nightly export of spindrel.events to Parquet in your own bucket.
- Export includes step payloads up to 4 MB; larger payloads are written as references.
v2.11.1
Signal ordering
- Fixed
- Two signals sent within 3 ms to the same run could be delivered out of order. They are now sequenced by the engine, not the client clock.
v2.11.0
Python 3.13
- Added
- Python 3.13 supported. The free-threaded build works in our test suite; we label it experimental until it has run in production for a quarter.
v2.10.0
Postgres 17 for self-hosting
- Added
- Changed
- The engine runs on Postgres 15, 16 or 17.
- Default history retention for self-hosted installs changed from forever to 30 days. Set history.retention to keep the old behaviour.
v2.9.3
Token scope for CI
- Security
- Deploy tokens can no longer read step payloads. Create a read token if your CI inspects runs.
v2.9.0
step.waitForSignal timeouts
- Added
- waitForSignal takes a timeout and returns false when it expires, instead of throwing.
v2.8.0
Replay a run against new code
- Added
- spindrel replay <runId> --local runs a recorded history against your working tree and reports the first step where the code diverges.
