v0.3.0 adds a replicated write-behind log. Fleets of two or more nodes acknowledge writes after peer fsync while bucket upload finishes later. In testing, this delivers 10× lower write latency and over 100× fewer Class A S3 operations. A v0.2.1 fleet can roll forward one node at a time.
-
Added support for Azure Blob Storage (
az://<BUCKET_NAME>). -
Added support for D1 databases, including the
celld d1CLI for migrations and SQL execution. -
Added support for cron triggers, with durable fleet-wide scheduling, retries for failed handlers, and recovery of one missed run after downtime.
-
Streaming and rewrapping request bodies are up to 70× faster, and text decoding is up to 44× faster.
-
WebSocket upgrades now work correctly for Durable Object subrequests and cross-script service bindings.
-
setInterval()now works correctly. -
celld deploynow accepts Node built-in specifiers (E.G.node:util) -
Each isolate now has a configurable V8 heap limit. celld refuses new hibernatable WebSockets and oversized SQL materialization near that limit, then resumes service after memory use falls.
-
Correctness fixes prevent overlapping alarm handlers, events from resuming in freed isolates, lost transactions at replication segment boundaries, and database corruption after eviction and reactivation.
