 # Changelog
 
+## 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
+
+- Added tikv-jemallocator dependency to rust/Cargo.toml and rust/crates/rustproxy/Cargo.toml
+- Enabled tikv_jemallocator as the global allocator in rust/crates/rustproxy/src/main.rs
+- Updated rust/Cargo.lock with tikv-jemallocator and tikv-jemalloc-sys entries
+- Modified package.json test script to run tsrust before tstest
+
 ## 2026-02-24 - 25.7.10 - fix(rustproxy)
 Use cooperative cancellation for background tasks, prune stale caches and metric entries, and switch tests to dynamic port allocation to avoid port conflicts
