- Issues
- SDK README quickstarts omit the required local server URL
- perf: PregelLoop._put_checkpoint re-scans all channels for DeltaChannel on every superstep
- perf(cli): merge cleanup steps and drop repeated WORKDIRs in generated Dockerfiles
- fix(langgraph): bind a bare resume to the single pending interrupt
- Cached node re-runs for duplicate Send inputs: only one task per cache key gets the cached writes
- SqliteStore: refresh_ttl=False in a batched get is ignored when another key in the batch refreshes
- feat(cli): add deploy scale command for compute and Postgres tiers
- SqliteStore never refreshes TTLs on read unless refresh_on_read is explicitly True, unlike PostgresStore
- In-memory runtime: cancelling a run that has been running for more than 240 s does not stop it
- checkpoint-sqlite: setup() guard catches std-lib sqlite3.OperationalError only — breaks non-stdlib drivers (e.g. sqlcipher)
