# 0.4.0 - 2026-07-27

- Replaced the unmaintained `rocksdb 0.24` binding with maintained
  `rust-rocksdb 0.51`, bundling RocksDB 11.1.2.

- Removed the duplicate legacy Rust crate, temporary migration module, duplicate
  tests, and release artifacts after the unchanged legacy test suite passed
  against the new backend.
- Added representative bidirectional RocksDB 10.4.2/11.1.2 migration checks.
- Raised the source-build requirement to Rust 1.91.
