Version History

v0.2.501 (Current)

  • Wallpaper-driven theme engine — themes auto-generated from wallpapers via K-Means in CIELAB color space (no hand-crafted themes)
  • Dynamic HEIC support — custom wallpapers ship as Apple-compatible single-file dynamic HEIC; macOS auto-switches dark/light
  • System wallpaper discovery — pulls themes from /System/Library/Desktop Pictures/ (macOS) and /usr/share/backgrounds/ (Linux)
  • dot theme rebuild — parallel K-Means generation (4 jobs), mtime-based caching, orphan cleanup
  • WCAG AAA enforcement — all generated themes pass 7:1 contrast for fg/bg, accent_text/accent, c15/bg
  • macOS accent from wallpaper hue — dot-theme-sync reads macos_accent from themes.toml and forces UI refresh
  • HEIC → PNG auto-conversion on Linux for non-HEIC-aware desktops
  • Build artifact redirection — Cargo, Go, pip, uv, Zig caches → /tmp/builds/ (cleared on reboot)
  • CI dedup — ci-enforced.yml reuses reusable-shell-lint.yml and reusable-test-suite.yml

v0.2.500

  • Added AI CLIs: Autohand Code, Mistral Vibe, Qwen Code, ZAI
  • Removed Cline CLI (broken upstream dependency)
  • Interactive mise installer for missing AI providers
  • Mise-first provisioning for all AI tools
  • User extension points: rc.d.local, modules.d, custom dot commands
  • SSH config hardening template
  • Ghostty and WezTerm terminal configs
  • Modern CLI tools: delta, fd, dust, bottom, lazygit, lazydocker, tldr
  • Auto-prewarm after dot apply
  • Expanded Atuin history filters

v0.2.497

  • Theme system with Catppuccin integration
  • Linux desktop parity (Niri, Waybar, Fuzzel)
  • AI tooling expansion (Kiro, OpenCode)
  • Coverage contracts and QA docs

v0.2.496

  • Verified chezmoi installer
  • Shell startup optimization
  • Property-based tests

Breaking Changes

If you are upgrading from v0.2.501 or earlier, note these changes:

  1. themes.toml is now generated — do not hand-edit. Run dot theme rebuild to regenerate from wallpapers
  2. Theme names changed — old hand-crafted names (e.g. catppuccin-mocha, macos-tahoe-dark with hardcoded palettes) are replaced by wallpaper-derived names. The picker only shows paired wallpaper themes.
  3. Wallpaper format — custom wallpapers should be dynamic HEIC (single file, both appearances). Use bash scripts/theme/merge-wallpaper.sh to merge separate dark/light pairs.
  4. Build caches relocated — Cargo/Go/pip/uv/Zig now write to /tmp/builds/. Restart your shell after upgrade so mise [env] picks up the new paths.

If you are upgrading from v0.2.501 or earlier:

  1. Cline CLI removed — if you used dot cline, switch to a different AI CLI
  2. AI tools now install through mise — run mise install to set up AI providers
  3. SSH config hardening — check ~/.ssh/config after apply, as it may change your current settings

Rollback

If something goes wrong after an upgrade:

# Quick rollback to previous state
dot rollback

# Rollback to specific backup
dot rollback status       # List available backups
dot rollback rollback-to 3  # Restore backup #3

# Git-based rollback
cd ~/.dotfiles
git log --oneline -10     # Find last good commit
git reset --hard HEAD~1   # Reset to previous commit
dot apply                 # Re-apply

Before You Upgrade

  • Run dot doctor — make sure everything is healthy
  • Run dot diff — review any pending changes
  • Back up custom configs: dot rollback backup
  • Read CHANGELOG.md for breaking changes

After You Upgrade

  • Run dot doctor — make sure the upgrade worked
  • Run dot prewarm — rebuild shell caches
  • Restart your shell: exec zsh
  • Test AI tools: dot ai
