# Changelog
## [1.6.0] - 2025-06-18
### 🗑️ Removed
- **youtube_get_channel_playlists**: Removed broken channel playlists functionality that consistently returned 0 results
- Removed all associated helper methods and types related to channel playlist discovery
- Cleaned up test files to remove non-functional tests
### 🎯 Rationale
- Channel playlists functionality was fundamentally broken due to YouTube API limitations
- 4 different discovery strategies all failed to return actual playlists for channels that demonstrably have playlists
- Removed to provide a cleaner, more reliable MCP server focused on working functionality
### ✅ Working Features Retained
- All transcript extraction functionality (single videos, batch processing)
- Playlist video listing and transcript extraction
- Channel video discovery
- Search functionality within transcripts
## [1.5.0] - 2025-06-18
### 🔧 Fixed

### 🚀 Added
- Video count extraction via iterator for accurate playlist information
- Multi-strategy playlist discovery: direct access → enhanced search → basic search → video-based discovery

### 📊 Impact
- Playlist info now returns accurate video counts (e.g., 14 videos for Snowflake Summit 2025)
