What shipped
- Dragonfly v2.0.0 released, marking a major version milestone after three years with expanded Redis and Valkey compatibility. Release
- SCAN command family refactored to use shared ScanResult container with packed storage for better performance on small scan keys. Pull request #8352
- SCAN result collection optimized by packing key bytes into shared backing storage, with fallback to individual strings after 1 MiB. Pull request #8314
- Hash field expiration accuracy improved with second-resolution deadline helpers and rounded deadlines for better replay determinism. Pull request #8340
- Valkey TCL CI gate expanded from stream/pubsub to 248 additional passing tests including incr, string, bitfield, bitops, scan, dump, and geo. Pull request #8343
- Lua performance optimized by retrieving string data pointers and byte lengths in single API calls during redis.call argument preparation. Pull request #8335
- Expired keys now hidden from read commands even when client pause is active, improving consistency. Pull request #8323
- Commands parked by CLIENT PAUSE now properly released when connections close, preventing SIGTERM/SHUTDOWN hangs. Pull request #8296
- Hash and zset listpack validation improved on RDB load to surface errors and prevent NULL-dereference crashes. Pull request #8328
- Script load contention reduced by releasing borrowed Lua interpreters immediately after compilation before journaling. Pull request #8321
Why it matters
Version 2.0.0 marks significant maturity and production readiness. This week's changes focus on performance optimizations for SCAN operations, improved hash expiration accuracy, expanded Valkey test compatibility, and critical fixes for client pause handling and script loading that improve reliability at scale.
