Merged
Conversation
- Add cflinuxfs5 to supported stacks in install_go.sh and package.sh - Add cflinuxfs5 Python dependencies (3.10.9, 3.11.15, 3.12.13, 3.13.9, 3.14.3) - Extend libffi and libmemcache to support cflinuxfs5 stack - Update config.json and VERSION for cflinuxfs5 release Dependencies use official S3-hosted binaries from buildpacks.cloudfoundry.org.
- Accept master's updated cflinuxfs5 dependencies from pipeline - Add cflinuxfs5 to libffi and libmemcache entries (binaries tested compatible)
- Use cflinuxfs4 Go binary for all stacks (compatible with cflinuxfs5) - Remove cflinuxfs3 support (deprecated stack) - Single version/SHA simplifies maintenance

cflinuxfs5 uses pip 26.0.1 (latest) cflinuxfs3/cflinuxfs4 use pip 25.2 (as before)
pip 26.0.1 requires flit-core build dependency which is not available. Use pip 25.2 which works correctly for all stacks.
Bump the minor version to 1.9.0
