# Stream-Mapparr Plugin Changelog (v0.6.0a -> v0.6.0b)
## New Features
* **Smart Analysis & Recommendations:**
* Added "What-if" analysis: Automatically tests matching at lower fuzzy thresholds (down to 65) to identify potential matches missed by current settings.
* Added Token Mismatch detection: Analyzes unmatched streams to suggest specific prefixes or suffixes (e.g., "US:", "HD") to add to the "Ignore Tags" list.
* **Enhanced CSV Export:**
* CSV files now include a detailed header section containing active settings, version info, and specific optimization recommendations based on the Smart Analysis.
* Rows now include data on potential matches found at lower thresholds.
* **Rate Limiting:** Added a "None (Disabled)" option to remove all artificial delays for faster processing on local networks.
* **Notifications:** Implemented WebSocket-based frontend notifications to display progress bars and success/error toasts during long-running operations.
## Improvements
* **Matching Logic:** Improved fuzzy matching algorithm to handle token overlap, better detecting matches where word order differs (e.g., "Channel Name US" vs "US Channel Name").
* **Maintenance:** Added a "Cleanup Orphaned Tasks" action to remove stale Celery Beat schedules left behind by older plugin versions.
* **Scheduling:** Updated schedule saving logic to provide immediate feedback on the next calculated run times in the local timezone.
## Internal
* Added `_get_matches_at_thresholds` and `_analyze_token_mismatch` methods to power the new recommendation engine.
* Refined `_clean_channel_name` to support optional country prefix removal.
