v0.9.0

Features

• Added sdt setup for interactive first-run configuration (name, email, and the repo’s check command), with optional enablement of automatic background grading.
• Expanded sdt config into a named-settings interface:
  • sdt config now lists all settings with resolved values and their source (local, global, default).
  • sdt config <name> explains a setting (expected values/choices, storage key, scope).
  • --unset support, plus --keys to show dotted-key mappings for on-disk config.
  • Shell completions now include setting-name completion for config.

Improvements

• Build defaults now produce a ReleaseFast binary on plain zig build, avoiding accidental Debug builds and large performance regressions.
• Switched the apricot dependency from a local path to a fetched URL to restore out-of-the-box builds on CI and fresh clones.
• Reduced agent session scanning overhead by skipping parsing of session files that cannot pertain to the current repo (for adapters that record absolute/cwd-resolved paths).
• Accelerated conflict-marker detection by caching blobs previously scanned as clean, avoiding repeated file reads across status runs.
• Background grading agents now retire themselves cleanly when the repo is removed; sdt doctor prunes orphaned agents.
• Documentation updated for the new setup/config flows and renamed config flags/keys.

Fixes

• Fixed scheduler tick budget configuration reading the wrong key and parsing the value incorrectly; now reads checks.tick_budget and supports duration parsing.
• Updated LFS and mesh configuration examples and error messages to match new setting names (e.g., lfs-url, lfs-smudge, mesh-every, mesh-verdicts).

Breaking Changes

• Configuration CLI and naming has changed:
  • sdt config checks.full ... is now documented/expected as sdt config check ....
  • Several settings moved to new names (e.g., mesh.interval-ms → mesh-every, mesh.verdicts → mesh-verdicts, lfs.url → lfs-url).
  • Dual-write config syntax changed to sdt config git-sync on --global.

Nightly (32aceaf)

Rolling nightly build from 32aceaf — 2026-08-20 07:41 UTC.

Prerelease built from the tip of master; may be unstable. Get it with sdt update --nightly.

v0.8.0

Improvements

• Garbage collection now bounds its root set using gc.retain (default 30d), allowing content abandoned by rewrites (amend/rebase/drop/squash) to be reclaimed after the retention window while always retaining anything reachable from branch refs.
• sdt gc now trims expired moments as part of collection (when not running with --dry-run), preventing old moment logs from pinning otherwise unreachable objects.
• Moment log trimming is more robust: when the only surviving keyframe would be cut, remaining moments are re-anchored so trimming can proceed without breaking reconstruction.

Breaking Changes

• Updated package version to 0.8.0.

v0.7.3

Fixes

• Prevented commands invoked with --help/-h from performing repository mutations (e.g., sdt save --help no longer checkpoints the working tree).
• Tightened conflict-marker detection to match only exact 7-character marker lines (optionally followed by a label), avoiding false positives from long runs of = in plain-text files (e.g., license heading underlines) and handling CRLF marker lines correctly.

v0.7.2

Fixes

• purge: Pathspec matching now follows .gitignore semantics. Slash-free specs (e.g., node_modules) match a path component at any depth, so nested directories are reached; leading / anchors matches to the repo root.

v0.7.1

Features

• purge now prunes .sdt/gitmap entries for changes that were replaced by the purge rewrite, preventing stale export mappings from masking history differences.

Improvements

• purge warns when dropped git mappings imply the next sdt push will rewrite commits and a shared Git remote will diverge (requiring a force push).
• Added purge statistics tracking for dropped git mappings (unmapped) and coverage via tests.

v0.7.0

Features

• Added sdt purge <path...> [--dry-run] [--force] to erase a path from every change across all branches, enabling sdt gc to reclaim space from mistakenly recorded build artifacts. Includes dry-run reporting and safety gating via --force.

Fixes

• .gitignore is now honored even when no colocated .git directory is present, preventing unintended capture of build output in sdt-only repositories.

Breaking Changes

• sdt purge rewrites history and resets moment and operation logs; purged content cannot be recovered via sdt undo.

v0.6.3

Features

• Added live progress reporting for long push operations, including mirroring history, packing objects, and sending objects.

Improvements

• Optimized history export during pushes by caching already-exported blobs, avoiding re-reading and re-compressing unchanged files across saved states.
• Enabled automatic pack-builder parallelism in libgit2 pushes (pb_parallelism = 0) to avoid single-core delta compression.
• Added automatic fallback to the system git push when libgit2 push fails (notably for large first pushes where pack building can stall the remote connection).

Fixes

• Prevented large first pushes from appearing hung by ensuring progress is finished/cleared on error paths.
• Added a regression test to verify first-push exports compress each blob once per unique content rather than once per saved state.

v0.6.2

Features

• sdt clone now shows live, in-terminal progress across phases: receiving objects, resolving deltas, checking out, and importing history.
• Import progress includes an estimated total commit count (when available) for a real denominator instead of a synthetic percentage.

Improvements

• Progress output is suppressed when stdout is not a TTY to keep logs and pipes clean.
• Clone/import status messages are clearer, with improved error detail on clone failures.
• Progress rendering utilities were centralized in ui for reuse (including consistent bars/spinners and human-readable byte formatting).

v0.6.1

Features

• sdt update now shows an interactive download progress bar when running in a terminal, and reports the downloaded size on completion.
• README now includes an animated demo of grading and rewinding.

Fixes

• macOS launchd background grading now runs with a real PATH, matching foreground grading behavior and avoiding “command not found” failures.

Improvements

• Ignore handling is now consistently based on .sdtignore and always ignores .sdt (and .git when present); removed remaining .grignore/legacy ignore merging.
• UI now tracks whether output is a TTY separately from color support, enabling cleaner terminal rendering decisions.

Breaking Changes

• Removed support for legacy .gr repositories and associated discovery paths; existing repos must be .sdt.
• Removed legacy config directory fallback (gr) and legacy environment variable spellings (e.g. GR_AUTHOR, GR_PROMPT, GR_AGENT).
• Sealing manifest file name changed to .sdtsealed (from .grsealed); existing sealed repos may require migration.
