Toolkit 6.1.0 made `restore_cache` try the on-premises Synology NAS before falling back to S3 on the macOS queue. Pinned at 6.0.0, every gem and SPM cache restore in this pipeline was paying billed S3 egress. The majors crossed (4.0.0, 5.0.0, 6.0.0) carry three breaking changes: `pr_changed_files` switching to exit codes, and two Windows-only script removals. This pipeline only calls `install_gems`, so none apply. --- Generated with the help of Claude Code, https://code.claude.com Co-Authored-By: Claude Code Opus 5 <noreply@anthropic.com>

The majors crossed (4.0.0, 5.0.0, 6.0.0) carry three breaking changes between them: pr_changed_files switching to exit codes, and two Windows-only script removals. Automattic-Tracks-iOS calls install_gems, so we're good.
As of
6.1.06.1.1, CI toolkit uses the Synology NAS on-premises on the macOS queue, falling back to S3 only when that's not available, resulting in lower S3 hits.
