 ## Tasks
-- [x] Read the discussion in [#209](https://github.com/SenteraLLC/ulabel/issues/209) and understand the requirements.
-- [x] Implement the fix requested in [#209](https://github.com/SenteraLLC/ulabel/issues/209).
-- [x] Build the fix and ensure the build succeeds by running `npm run build`.
-- [x] Receive confirmation that the fix works as expected.
-- [x] Configure Jest to suppress verbose stack traces (added --noStackTrace flag)
-- [x] Fix class ID test to check ID is not in existing list (implementation-agnostic)
-- [x] Increase max workers from 1 to 2 (reduced test time from 200s+ to ~23s)
-- [ ] Fix remaining unit test failures (6 failures, 14 passed)
-  - Spatial payload tests need DOM mocking
-  - ID payload tests need DOM mocking
-  - Note: Some error messages contain minified code context - this is expected when testing against dist/ulabel.js
-- [x] Refactor e2e tests to use utility functions
-  - [x] Create init_utils.js with wait_for_ulabel_init
-  - [x] Create annotation_utils.js with get_annotation_count, get_annotation_by_index, get_all_annotations
-  - [x] Create mode_utils.js with switch_to_mode
-  - [x] Create subtask_utils.js with get_current_subtask_key, switch_to_subtask, get_subtask_count
-  - [x] Update basic-functionality.spec.js to use new utilities
-  - [x] All 6 basic functionality tests passing
-- [x] Refactor tests/ folder to use snake_case naming convention
-  - [x] Updated all utility function names to snake_case
-  - [x] Updated all variable names in e2e tests to snake_case
-  - [x] Updated all variable names in unit tests to snake_case
-  - [x] Updated all variable names in setup.js to snake_case
-  - [x] Updated all variable names in utility files to snake_case
-  - [x] Verified unit tests pass (14 passed)
-  - [x] Verified e2e tests pass (6 passed)
+- [x] Read the description in [#164](https://github.com/SenteraLLC/ulabel/issues/164)
+  - [x] Write a clear summary of the requested change
+  - [x] Propose some options of how to proceed. Wait for user input to decide which to try first.
+
+### Decision: Proceeding with Option 3 (Webpack modernization + dependency cleanup)
+
+#### Step 1: Move dependencies to devDependencies
+- [x] Move `@turf/turf` from dependencies to devDependencies
+- [x] Move `jquery` from dependencies to devDependencies
+- [x] Move `polygon-clipping` from dependencies to devDependencies
+- [x] Move `uuidv4` from dependencies to devDependencies
+- [x] Test: Run `npm install` and verify it works
+- [x] Test: Run `npm run build` and verify output is identical (both files 1039.6 KB)
+
+#### Step 2: Enable and modernize webpack minification ✅ COMPLETE
+- [x] Remove commented-out UglifyJsPlugin code (deprecated)
+- [x] Enable webpack 5's built-in TerserPlugin for minification  
+- [x] Configure it to only minify `ulabel.min.js`, not `ulabel.js`
+- [x] Test: Run `npm run build` and verify both files are created
+- [x] Test: Verify `ulabel.js` is NOT minified (readable) - 2.33 MB with webpack runtime and formatted code
+- [x] Test: Verify `ulabel.min.js` IS minified (smaller size) - 1.02 MB minified
+- [x] Test: Run `npm run lint` - No errors
+- [x] Note: File size difference (2.33 MB vs 1.02 MB) is expected - readable version includes webpack runtime overhead
+
+#### Step 3: Verify and document ✅ COMPLETE
+- [x] Compare file sizes before/after
+  - Before: Both files 1039 KB (both minified, minification was disabled)
+  - After: ulabel.js 2.33 MB (readable), ulabel.min.js 1.02 MB (minified)
+  - Result: Minification now working correctly, file size increase for non-min version is expected
+- [x] Update CHANGELOG.md with changes
+- [x] Document any findings or recommendations
+
+#### Step 4: Security and dependency updates ✅ COMPLETE
+- [x] Run `npm audit` to identify vulnerabilities
+- [x] Fix 12 vulnerabilities using `npm audit fix`
+- [x] Apply breaking changes for remaining issues with `npm audit fix --force`
+- [x] Update `typescript-eslint` packages to be compatible with ESLint 9.37.0
+- [x] Fix linting issues in `tests/e2e/fixtures.js`
+- [x] Verify all tests still pass (28 unit tests + 36 e2e tests)
+- [x] Final audit: 0 vulnerabilities
+
+#### Step 5: Configure package exports for minified by default ✅ COMPLETE
+- [x] Update `main` and `module` fields to point to `dist/ulabel.min.js`
+- [x] Add `exports` field with options: `.` (minified), `./min` (minified), `./debug` (unminified)
+- [x] Update `unpkg` field to serve minified version by default
+- [x] Update README.md with usage examples for both minified and unminified versions
+- [x] Document clear import patterns for users

+
+## [0.20.0] - Oct 15th, 2025
+- Add `fly-to` functions, which sets the zoom and focus to a specific annotation
+  - `fly_to_next_annotation()`
+  - `fly_to_annotation_id()`
+  - `fly_to_annotation()`
+- Add `Tab` and `Tab+Shift` default keybinds to fly-to the next/previous annotation, respectively
+  - Keybinds are configurable:
