 # Changelog
 
+## 2025-12-08 - 6.0.0 - BREAKING CHANGE(watchers)
+Replace polling-based write stabilization with debounce-based event coalescing and simplify watcher options
+
+- Remove polling-based WriteStabilizer (ts/utils/write-stabilizer.ts) and related waitForWriteFinish logic
+- Introduce debounce-based coalescing (debounceMs) for Node and Deno watchers (ts/watchers/watcher.node.ts, ts/watchers/watcher.deno.ts)
+- Change IWatcherOptions: remove stabilityThreshold/pollInterval/maxWaitTime and add debounceMs
+- Default watcher options updated to use debounceMs = 100
+- Node/Deno watchers now skip editor temp files earlier, debounce duplicate events, and emit events directly (no size polling)
+- Updated default watcher creation in Smartwatch to pass debounceMs
+- Update package.json build script to run 'tsbuild tsfolders'
+
+## 2025-12-08 - 5.1.0 - feat(watchers)
+Improve write stabilization and ignore temporary editor files
+
+- Add maxWaitTime option (ms) to IWatcherOptions and WriteStabilizer to cap how long stabilization will wait (default: 1000ms).
+- WriteStabilizer: reduce default stabilityThreshold from 300ms to 100ms and track write start time to enforce maxWaitTime and avoid indefinite polling.
+- Node and Deno watchers: detect and ignore common temporary/editor files (e.g. *.tmp.*, *.swp, *.swx, trailing ~, .#*) to prevent spurious events from atomic saves.
+- Node watcher: treat rename (atomic-save) events as already-complete files and emit add/change immediately without stabilization.
+- Deno watcher: use the configured maxWaitTime and polling-based stabilization for modify events to ensure consistent behavior across runtimes.
+
+## 2025-11-30 - 5.0.0 - BREAKING CHANGE(@push.rocks/smartwatch)
+Rename package and update branding/docs: switch from @push.rocks/smartchok to @push.rocks/smartwatch, update repository/homepage/bugs URLs and author, and refresh README examples and install instructions.
+
+- Package name changed from @push.rocks/smartchok to @push.rocks/smartwatch in package.json
+- Repository, homepage and issue URLs updated to point to the new smartwatch repository
+- Author changed to Task Venture Capital GmbH in package metadata
+- README updated: install commands, import examples and references now use @push.rocks/smartwatch
+- Documentation text and branding updated throughout README (project name, internal references)
+
 ## 2025-11-30 - 4.0.1 - fix(readme)
 Update README: refine description and clarify trademark/legal information
