September 2025 — openwrt/packages: Delivered two high-impact feature upgrades with build, security, and deployment improvements that enhance developer productivity and runtime reliability for Erlang and mail tooling in the OpenWrt ecosystem.

OpenWrt packages — August 2025: Delivered a coordinated upgrade across networking, media, core tooling, and security tooling. The work modernizes protocol support, strengthens security, and improves build maintainability, enabling faster delivery of features with reduced patch drift. Key features delivered: - Curl network protocol configuration enhancements: update curl to 8.15.0 with consolidated HTTP/3 and QUIC configurations, disable IPFS support, rename the HTTP/2 configuration option, and align https-dns-proxy build options to reflect latest curl capabilities. - HTTP/3/HTTP/2 stack upgrade: upgrade nghttp3 to 1.11.0, nghttp2 to 1.66.0, and ngtcp2 to 1.15.0; adapt builds, update package descriptions, and integrate OpenSSL where applicable for improved security and compatibility. - Media processing libraries upgrade: FFmpeg 6.1.3, libjpeg-turbo 3.1.1, libpng 1.6.50, and ImageMagick 7.1.2.1; remove/adjust upstream patches and update build configurations to reflect new versions. - Core system and tooling upgrades: APR 1.7.6, Subversion 1.14.5, whois 5.6.4, Rust 1.89.0, bottom 0.11.1, libzip 1.11.4, bc 1.08.2, and lksctp-tools 1.0.21; updated hashes and build configurations. - Proxy and security tooling upgrades: Squid 7.1 and ClamAV 1.4.3 with simplified patches and updated source URLs. Major bugs fixed: - Resolved compatibility and build issues arising from protocol and library upgrades; aligned curl options with new capabilities; ensured dependent packages build cleanly against updated stacks. Overall impact and accomplishments: - Strengthened security posture, protocol support, and maintainability of the OpenWrt packaging ecosystem; reduced patch drift and improved build reliability, setting a solid foundation for future feature work. Technologies/skills demonstrated: - Dependency management across curl, HTTP/3/HTTP/2 stacks, media libraries, and core toolchains; build system maintenance and patch hygiene; security-focused upgrade practices; cross-component coordination and documentation updates.
