- - Updated HTTP/2 defaults (max streams 1024, reduced window sizes) and added HTTP/1.1 CONNECT proxy support, header removal patterns, and per‑route compressor overrides.
- - Fixed critical security and stability issues including TLS inspector regression, DNS cache use‑after‑free, listener socket creation in network namespaces, and several proxy timeout/crash bugs.
- - Expanded observability and extensibility with configurable metric eviction, logging ABI for dynamic modules, new Redis commands, reverse‑tunnel support, and richer external authz/gRPC per‑route configurations.
