v0.9.0: Performance optimizations + UI simplification

Performance (ported from Linearr):
- rapidfuzz C extension for Levenshtein (20-50x faster when available)
- Pure Python early termination fallback via threshold parameter
- Normalization cache: precompute_normalizations() avoids redundant normalize_name() calls
- fuzzy_match() and find_best_match() use cached results
- ETA updated from 7.73s to 0.1s per item

UI simplification:
- Profile Name: free text → dynamic dropdown from database
- Match Sensitivity: number 0-100 → named presets (Relaxed/Normal/Strict/Exact)
- Tag Handling: 4 booleans → single dropdown (Strip All/Keep Regional/Keep All)
- Channel Database: per-country booleans → single dropdown
- All changes backward compatible with legacy field IDs

+# Stream-Mapparr CHANGELOG
+
+## v0.9.0 (April 4, 2026)
+**Type**: Performance & UI Enhancement Release
+
+### Performance Optimizations (ported from Linearr plugin)
+
+**Levenshtein Acceleration**:
+- Uses `rapidfuzz` C extension when available (20-50x faster)
+- Pure Python fallback with early termination via new `threshold` parameter
+- Combined effect: matching 94 channels x 3,362 streams in ~2s (was ~5 minutes)
+
+**Normalization Cache**:
+- Added `precompute_normalizations()` to cache stream name normalization once before matching loops
+- `fuzzy_match()` and `find_best_match()` use cached results via `_get_cached_norm()` / `_get_cached_processed()`
+- Eliminates redundant `normalize_name()` calls across all 3 matching stages
+- Cache fallback uses stored ignore flags for consistency
+
+**ETA Calculation**:
+- Updated `ESTIMATED_SECONDS_PER_ITEM` from 7.73s to 0.1s to reflect actual performance
+
+### UI Simplification
+
+**Profile Name**: Free-text input replaced with dynamic dropdown populated from database
+
+**Match Sensitivity**: Numeric threshold (0-100) replaced with named presets:
+- Relaxed (70), Normal (80), Strict (90), Exact (95)
+
+**Tag Handling**: Four separate boolean toggles consolidated into single dropdown:
+- Strip All Tags (default), Keep Regional Tags, Keep All Tags
+
+**Channel Database**: Per-country boolean toggles consolidated into single dropdown:
+- None, individual country, or All databases
+
+All changes are backward compatible — legacy field IDs still work as fallbacks.
+
+### Files Modified
+- `fuzzy_matcher.py` v26.095.0100: Cache system, rapidfuzz support, early termination
+- `plugin.py` v0.9.0: Precompute calls, UI fields, settings resolvers
+- `plugin.json` v0.9.0: Updated field definitions
+
+### Version Compatibility
+| Plugin Version | Required fuzzy_matcher |
+|---------------|------------------------|
+| 0.9.0 | 26.095.0100+ |
+| 0.8.0b | 26.018.0100+ |
+| 0.7.4a | 26.018.0100+ |
+
+---
+
+## v0.8.0b (March 11, 2026)
+**Type**: Bugfix Release
+**Severity**: HIGH (ORM Migration)
+
+### Bug Fixed: Invalid `group_title` Field on Stream Model
+
+**Issue**: After migrating from HTTP API to Django ORM in v0.8.0a, the plugin used `group_title` as a field name on the Stream model. This field does not exist — the correct field is `channel_group` (a ForeignKey to `ChannelGroup`). Any action that loads streams (Add Streams, Preview Changes, Load/Process Channels) would fail with:
+```
+Cannot resolve keyword 'group_title' into field.
+```
+
+**Root Cause**: During the ORM migration, the old API response field name `group_title` was carried over into ORM `.values()` queries, but the Django model uses `channel_group` (FK) instead.
+
+**Fix**: Replaced `group_title` with `channel_group__name` (Django FK traversal) in two locations:
+- `_get_all_streams()`: Stream data query
+- `_get_stream_groups()`: Distinct stream group name query
+
+**Files Modified**:
+- `plugin.py` v0.8.0b: Fixed ORM field references
+- `plugin.json` v0.8.0b: Version bump
+
+---
+
+## v0.7.4a (January 18, 2026)
+**Type**: Critical Bugfix Release
+**Severity**: HIGH (Stream Matching)
+
+### Bug Fixed: 4K/8K Quality Tags Not Removed During Normalization
+
+**Issue**: Streams with "4K" or "8K" quality suffixes were not matching correctly because the space normalization step was splitting "4K" into "4 K" before quality patterns could remove it.
+
+**Example**:
+- Stream: `┃NL┃ RTL 4 4K`
+- Expected: Tag removed → "RTL 4" → matches channel
+- Actual: "4K" split to "4 K" → patterns fail → "RTL 4 4 K" → no match
+
+**Root Cause**: The digit-to-letter space normalization (`re.sub(r'(\d)([a-zA-Z])', r'\1 \2', name)`) transformed "4K" into "4 K" before quality patterns could match and remove "4K".
+
+**Pattern Observed**:
+| Quality Suffix | Affected? | Reason |
+|---------------|-----------|--------|
+| HD, SD, FHD, UHD | No | All letters, not split |
+| 4K, 8K | **Yes** | Digit+letter split to "4 K", "8 K" |
+
+**Fix**: Quality patterns are now applied BEFORE space normalization to prevent "4K"/"8K" from being broken.
+
+**Files Modified**:
+- `fuzzy_matcher.py` v26.018.0100: Moved quality pattern removal before space normalization
+- `plugin.py` v0.7.4a: Updated version and minimum fuzzy_matcher requirement
+

+
+## v0.7.3c (December 23, 2025)
+**Type**: Critical Bugfix Release
+**Severity**: HIGH (Unicode tag users)
+
+### Bug Fixed: Custom Ignore Tags with Unicode Characters Not Working
+
+**Issue**: Custom ignore tags containing Unicode or special characters (like `┃NLZIET┃`) were completely ignored during normalization, causing all channels to fail matching.
+
+**Root Cause**: Code used regex word boundaries (`\b`) for all custom tags. Word boundaries only work with alphanumeric characters. Unicode characters like `┃` (U+2503) are not word characters.
+
+**Fix**: Smart tag detection - only use word boundaries for pure alphanumeric tags, use literal matching for Unicode/special character tags.
+
+---
+
+## v0.7.4 (December 22, 2025)
+**Type**: Critical Bugfix Release
+**Severity**: HIGH (Matching Accuracy)
+
+### Bug #1 Fixed: Substring Matching Too Permissive
+
+**Issue**: "Story" matched "HISTORY" at threshold 80 because substring matching didn't validate semantic similarity.
+
+**Fix**: Added 75% length ratio requirement for substring matches.
+
+### Bug #2 Fixed: Regional Tags Stripped Despite Setting
+
+**Issue**: `Ignore Regional Tags: False` didn't work - "(WEST)" was still being removed by MISC_PATTERNS and callsign patterns.
+
+**Fix**: Conditional MISC_PATTERNS application and callsign pattern with negative lookahead for regional indicators.
+
+---
+
+## v0.7.3 (December 21, 2025)
+**Type**: Enhancement Release
+
+### Added FuzzyMatcher Version to CSV Headers
+
+CSV exports now show both plugin and fuzzy_matcher versions for better troubleshooting:
+```csv
+# Stream-Mapparr Export v0.7.3
+# FuzzyMatcher Version: 25.354.1835
+```
+
+---
+
+## v0.7.2 (December 20, 2025)
+**Type**: Bugfix Release
+
+### Fixed: Incomplete Regional Patterns
+
+Updated fuzzy_matcher dependency to include all 6 US timezone regional indicators (East, West, Pacific, Central, Mountain, Atlantic) instead of just "East".
+
+---
+
+## v0.6.x Series
+
+### v0.6.17 - M3U Source Prioritization
+Added M3U source priority ordering for stream sorting.
+
+### v0.6.16 - Channel Loading Fix
+Fixed channel loading issues with profile filtering.
+
+### v0.6.15 - Smart Stream Sorting
+Implemented quality-based stream sorting using stream_stats (resolution + FPS).
+
+### v0.6.14 - CSV Headers Enhancement
+Added comprehensive CSV headers with action name, execution mode, and settings.
+
+### v0.6.13 - Channel Groups Filter Fix
+Fixed Sort Alternate Streams ignoring channel groups filter setting.
+
+### v0.6.12 - Sort Streams Fix
+Critical fix for Sort Alternate Streams action using wrong API endpoint.
+
+### v0.6.11 - Dry Run Mode & Sort Streams

+
+### v0.6.10 - Lock Detection Enhancement

+
+### v0.6.8 - Quality-Based Stream Ordering
+Automatic quality-based stream ordering when assigning streams.
+
+### v0.6.7 - Deduplication & Decade Fix
+Stream deduplication, decade number preservation ("70s" not matching "90s"), plus sign handling.
+
+### v0.6.3 - Numbered Channel Fix
+Fixed false positive matches for numbered channels (Premier Sports 1 vs 2).
+
+### v0.6.2 - Token Matching Fix
+Fixed Sky Cinema channels matching incorrect streams.
+
+### v0.6.0 - Major Refactor
+Replaced Celery Beat with background threading scheduler, operation lock system, WebSocket notifications, centralized configuration.
+
+---
+
+## Upgrade Instructions
+
+**For v0.7.4a**:
+1. Replace `plugin.py` with v0.7.4a
+2. Replace `fuzzy_matcher.py` with v26.018.0100
+3. Restart Dispatcharr container
+4. Re-run "Match & Assign Streams"
+
+**IMPORTANT**: Both files must be updated together!
