+# [2.1.2] - TBD
+- Change - GitHub Actions workflows now use native ARM64 runners (`ubuntu-24.04-arm64`) instead of QEMU emulation for multi-platform builds, to reduce build times.
+- Change - Optimized Dockerfile layer ordering to improve cache hit rates - local config files moved to end to prevent invalidating heavy system installation layers.
+- Change - Added BuildKit cache mounts for apt package installation and PHP extension compilation, to reduce subsequent build times.
+- Change - Added `IPE_CACHE_DIR` environment variable to cache PHP extension downloads and compiled artifacts across builds.
+- Change - Implemented platform-specific registry caching (separate caches for amd64/arm64) to prevent cache conflicts and maximize reuse.
+
 # [2.1.1] - 2025-11-04
 - Change - Optimize docker builds and workflows for slic and WordPress containers.

 # [2.1.2] - TBD
-- Change - GitHub Actions workflows now use native ARM64 runners (`ubuntu-24.04-arm64`) instead of QEMU emulation for multi-platform builds, to reduce build times.
+- Change - GitHub Actions workflows now use native ARM64 runners (`ubuntu-24.04-arm`) instead of QEMU emulation for multi-platform builds, to reduce build times.
 - Change - Optimized Dockerfile layer ordering to improve cache hit rates - local config files moved to end to prevent invalidating heavy system installation layers.
 - Change - Added BuildKit cache mounts for apt package installation and PHP extension compilation, to reduce subsequent build times.
 - Change - Added `IPE_CACHE_DIR` environment variable to cache PHP extension downloads and compiled artifacts across builds.
