Actix-web v4.13.0 — HTTP/2 upload perf boost, TCP_NODELAY config, min Rust 1.88
release
HIGH
Actix-web 4.13.0 (released 2026-02-18) raises the MSRV to Rust 1.88 and delivers: boosted HTTP/2 upload performance via larger flow control windows, new named URL parameter handling methods, TCP_NODELAY configuration options, fixes for panic with path rewriting, 206 Partial Content uncompressed responses, and an experimental route introspection feature for reporting configured routes. This is the primary web framework for ODS backend services.

ODS Impact
All ODS Rust services use Actix-web as the preferred web framework. HTTP/2 upload performance improvements benefit DocStore file upload throughput and PDF Engine input processing. TCP_NODELAY option reduces latency for M2M service-to-service calls. The MSRV bump to Rust 1.88 means Rust toolchain must be at 1.88+ (tracked version is 1.94.1, no issue). Update actix-web dependency to 4.13.0 in all service Cargo.toml files.
