+## [1.0.0] - 2026-02-28
+
+Initial public release.
+
+### Sync engine
+
+- Bidirectional sync between Apple Reminders and todo.txt via a three-way
+  diff against persisted state (`state.json`)
+- Last-write-wins (LWW) conflict resolution per field, with configurable
+  timestamp tolerance (`timestamp_tolerance_secs`) to absorb iCloud rounding
+- Hash-based change detection on both sides (no spurious updates)
+- Bootstrap reconciliation by title + due date on first sync, so existing
+  tasks and reminders are linked without duplication
+- EID relinking: detects iCloud external-identifier reassignment and
+  re-links by content hash instead of treating it as delete + create
+- Recurrence: EventKit recurrence rules ignored on import; TTDL manages
+  `rec:` recurrence locally and `remtodo` propagates completions
+
+### Sentinel `eid:` values
+
+Three reserved tags let tasks opt out of sync or trigger ejection:
+
+- `eid:na` — permanent local opt-out, never pushed to Reminders
+- `eid:na/<orig>` — eject a synced reminder and keep task local
+- `eid:ns/<orig>` — eject a synced reminder and resume normal rules
+
+### Configuration
+
+- Per-list sync configuration: `auto_context`, `push_filter`, `sticky_tracking`
+- Configurable priority mapping: Reminders integers → `context:NAME`,
+  `priority:A`–`Z`, or `none` (default: priority 9 → `@today`)
+- Per-field writeback control: set `false` to make todo.txt authoritative
+  for `title`, `due_date`, `priority`, or `is_completed`
+- Sticky tracking modes: `auto` (origin-aware release), `always`, `never`
+
+### Safety guards
+
+- Bulk-delete threshold: aborts if more than `max_delete_percent` (default 50%)
+  of tracked reminders would be deleted in one cycle
+- First-sync protection: no deletions on the first sync for a list
+- Task-count coherence check: aborts if the output file shrinks unexpectedly
+- Post-sync consistency verification: detects duplicate EIDs and hash mismatches
+
+### Operations
+
+- `remtodo sync` — one-shot sync with optional `--dry-run` and `--config`
+- `remtodo restore` — reverts Reminders mutations and restores todo.txt +
+  state.json from pre-sync backups
+- `remtodo install` / `status` / `uninstall` — launchd agent management
+- Lock file (PID-based) prevents concurrent sync runs
+- Graceful SIGINT/SIGTERM handling with per-list rollback
+
+### Infrastructure
+
+- Swift EventKit helper (`reminders-helper`) with batch create/update/delete
+- `make install` builds the Rust binary inside `nix develop` and copies both
+  binaries to `~/.local/bin`; Swift must be pre-built outside `nix develop`
+- nix flake dev environment (`nix develop`)
+- GitHub Actions CI: `cargo fmt`, `cargo clippy`, `cargo test`, `swift build`
+- Dependabot for Cargo and GitHub Actions updates
