v2.0.0

[romange]

Dragonfly v2.0.0

We have been waiting three years to bump the major version.

While this specific release does not add new major features by itself, it marks a significant milestone in our maturity, performance, and production readiness.

Dragonfly v2.0.0 expands Redis and Valkey compatibility with Valkey 9 RDB loading, GEOSEARCHSTORE, and improved replication backlog controls. Performance work reduces connection-processing and memory-accounting overhead while adding tighter controls for defragmentation and buffer retention. Tiered storage, cluster migration, streams, compressed lists, and RESP3 behavior received substantial correctness improvements. This release also strengthens RESTORE validation against malformed or incompatible payloads.

Highlights

• Added Valkey 9 RDB support and GEOSEARCHSTORE. (feat: add rdb valkey support #8251, feat(geo): add GEOSEARCHSTORE command #7984)
• Reduced connection-accounting, parsing, buffering, and RDB serialization costs. (perf(facade): simplify connection memory refreshes #8246, perf(facade): batch parser memory refreshes #8225, chore(server): Release serializer buffer capacity over limit #8140, feat(facade): reclaim (shrink) connection buffers #8005)
• Hardened RESTORE, cluster migration, tiered storage, streams, RESP3, and compressed-list handling. (fix(rdb): reject a hash with duplicate fields on RESTORE #8260, fix(cluster): don't crash when migration finalize pause times out #8240, fix(tiering): preserve offloaded hashes during serialization #8026, fix: wake blocked XREADGROUP when its stream is deleted #8015, fix(facade): Handle RESP3 null array response #8085, fix(qlist): fix malloc_size_ accounting for compressed nodes #8014)

Commands

• Added GEOSEARCHSTORE with radius or box queries, sorting, limits, distance scores, ACL enforcement, and journaling. (feat(geo): add GEOSEARCHSTORE command #7984)
• Added MEMORY DEFRAGMENT-SEGMENTS [threshold] to reclaim sparsely used DashTable pages and report page usage. (feat(server): Add defrag table segments command #7995)

Performance
