v0.1.23

Upgrade note: legacy turn checkpoints

Tcode no longer creates hidden Git checkpoint refs. If you used a build that included
turn checkpoints, run this once inside each affected repository to remove the old refs:

git for-each-ref --format='delete %(refname)' refs/tcode/checkpoints/ | git update-ref --stdin

This does not change branches, commits, the index, or workspace files. The unreferenced
snapshot objects become eligible for Git's normal garbage collection.

Platform notes

• macOS 12+: these test builds are not signed or notarized. After moving the app to Applications, clear Gatekeeper quarantine with:

  xattr -dr com.apple.quarantine /Applications/Tcode.app

• Windows: Microsoft Edge WebView2 Runtime is required. It is included with Windows 11.

• Linux: requires ALSA, Fontconfig, Wayland/X11 client libraries, libgbm, the Vulkan loader, and a working Vulkan ICD/graphics driver.

Packages are uploaded as soon as each platform build completes. macOS artifacts are
architecture-specific. Windows MSI/NSIS and Linux AppImage packages are not currently
produced. SHA256SUMS.txt is added after every platform package has finished.
