 # Changelog
 
+## 2026-02-26 - 25.8.3 - fix(smartproxy)
+no code or dependency changes detected; no version bump required
+
+- No files changed in the provided diff (No changes).
+- package.json version remains 25.8.2.
+- No dependency or source updates detected; skip release.
+
+## 2026-02-26 - 25.8.2 - fix(connection)
+improve connection handling and timeouts
+
+- Flush logs on process beforeExit and avoid calling process.exit in SIGINT/SIGTERM handlers to preserve host graceful shutdown
+- Store protocol entries with a createdAt timestamp in ProtocolDetector and remove stale entries older than 30s to prevent leaked state from abandoned handshakes or port scanners
+- Add backend connect timeout (30s) and idle timeouts (5 minutes) for dynamic forwards; destroy sockets on timeout and emit logs for timeout events
+
+## 2026-02-25 - 25.8.1 - fix(allocator)
+switch global allocator from tikv-jemallocator to mimalloc
+
+- Replaced tikv-jemallocator with mimalloc in rust/Cargo.toml workspace dependencies.
+- Updated rust/crates/rustproxy/Cargo.toml to use mimalloc as a workspace dependency.
+- Updated rust/Cargo.lock: added mimalloc and libmimalloc-sys entries and removed tikv-jemallocator and tikv-jemalloc-sys entries.
+- Changed the global allocator in crates/rustproxy/src/main.rs from tikv_jemallocator::Jemalloc to mimalloc::MiMalloc.
+- Impact: runtime memory allocator is changed which may affect memory usage and performance; no public API changes but recommend testing memory/performance in deployments.
+
 ## 2026-02-24 - 25.8.0 - feat(rustproxy)
 use tikv-jemallocator as the global allocator to reduce glibc fragmentation and slow RSS growth; add allocator dependency and enable it in rustproxy, update lockfile, and run tsrust before tests
