Oct 1, 2025October 2025 (macports/macports-ports) monthly summary: - Scope and delivery: Executed a broad batch of port updates to improve security, compatibility, and maintenance across the repository. Delivered extensive toolchain updates, new ports, and policy-driven enhancements that reduce technical debt and prepare the stack for upcoming platform changes. Key features delivered and updates: - Google Cloud SDK updated in batch to 541.0.0 and 542.0.0, with subsequent updates to 543.0.0 and 544.0.0 to maintain cloud tooling parity. - OpenJDK updates across multiple families and vendors: JetBrains OpenJDK 21 updated to 21.0.8-b1140.54 and 21.0.8-b1148.57; OpenJDK 21 further updated to 21.0.9; OpenJDK 25 family updated to 25.0.1 across GraalVM, Corretto, and OpenJDK 25; extensive OpenJDK 11/17/21 updates across vendors; livecheck improvements for OpenJDK 17. - End-of-life governance introduced for OpenJDK 25 variants and Oracle JDKs: added end-of-support dates for OpenJDK 25 Corretto and Microsoft variants, plus EOL dates for openjdk*-oracle variants. - Gemini CLI: new port added and updated across 0.8.x, followed by updates to 0.9.0 and 0.10.0 to align with upstream releases. - Additional feature updates: Micronaut 4.10.0; Groovy 5.0.2; Kotlin 2.2.21; Spring Boot CLI 3.5.7; OSXPhotos 0.73.2, 0.73.3, and 0.73.4; K9s 0.50.15; py-whenever 0.8.10; OpenJDK 8 Corretto 8.472.08.1. Major bugs fixed: - OpenJDK 25: build without -reproducible flag on macOS 12 and older (stability for older macOS builds). - OpenJDK 25: patch format fix to ensure clean patch application and reproducible builds. - OpenJDK 25 and related tooling: updated end-of-life information to support governance and compliance. Overall impact and accomplishments: - Strengthened security and compliance posture with up-to-date toolchains and explicit EOL data for critical JDK variants. - Reduced maintenance overhead by consolidating updates into batch releases and improving patching reliability. - Improved developer experience through newer CLI tools (Gemini CLI), modernized runtimes (OpenJDK 21/25 stacks, 11/17/21 across vendors), and refreshed productivity tooling (Micronaut, Groovy, Kotlin, Spring Boot CLI). Technologies and skills demonstrated: - Release engineering and batch port updates across a large ecosystem; cross-vendor OpenJDK maintenance; end-of-life governance; patch management and bugfix discipline; livecheck and port modernization; macOS-specific build considerations; and multi-portfolio coordination for a cohesive runtime/tooling stack.
