 # Changelog
 
+## 2026-03-02 - 5.3.1 - fix(mail)
+add periodic cleanup timers and proper shutdown handling for bounce manager and delivery queue; avoid mutating maps during iteration and prune stale rate-limiter stats to prevent memory growth
+
+- BounceManager: add cleanupInterval to periodically remove bounce records older than 7 days and log removals; add stop() to clear the interval and prevent leaks
+- UnifiedDeliveryQueue: introduce cleanupTimer started in startProcessing() and cleared in stopProcessing(); cleanupOldItems now collects IDs first to avoid mutating the Map while iterating and logs cleaned items; shutdown now relies on stopProcessing to clear timers
+- UnifiedRateLimiter: prune stale stats.byIp and stats.byPattern entries for IPs/patterns that no longer have active counters or blocks to reduce memory usage and keep stats accurate
+- Auto-cleanup tasks log errors rather than throwing to avoid crashing processing loops
+
+## 2026-02-26 - 5.3.0 - feat(mailer-bin)
+use mimalloc as the global allocator for mailer-bin
+
+- Add mimalloc dependency to workspace Cargo.toml
+- Enable workspace mimalloc in rust/crates/mailer-bin/Cargo.toml
+- Register mimalloc as the #[global_allocator] in mailer-bin/src/main.rs
+- Update Cargo.lock with new mimalloc and libmimalloc-sys entries
+
+## 2026-02-26 - 5.2.6 - fix(postinstall)
+remove legacy postinstall binary installer and packaging entry
+
+- Deleted scripts/install-binary.js (legacy postinstall script that downloaded platform-specific binaries).
+- Removed reference to scripts/install-binary.js from package.json "files" array so the installer is no longer included in published packages.
+- This prevents automatic binary downloads during npm install and reduces package size; recommend a patch version bump.
+
 ## 2026-02-26 - 5.2.5 - fix(package)
 remove CLI bin wrapper and exclude bin/ from published files
