Apr 1, 2025April 2025 delivered architecture-level improvements and release automation across two repositories, driving security, maintainability, and broader platform support. In influxdata/official-images, SapMachine Docker images were restricted to amd64 and updated to current SapMachine versions (24, 21, 17, 11) across Ubuntu-based Dockerfiles, removing support for arm64v8 and ppc64le. In SAP/jmc, the release workflow was enhanced to upload aarch64 Linux binaries, improving accessibility for ARM64 systems and aligning with the broader SapMachine release cadence.
