## Major Performance and Infrastructure Improvements

This release focuses on core infrastructure improvements, performance optimizations, and reliability enhancements:

### Core Infrastructure Improvements
* **HTTP CLIENT CONSOLIDATION**: Unified authentication system supporting both OAuth2 (`auth = "token"`) and API key (`auth = "key"`) authentication across all functions
* **STANDARDIZED ERROR HANDLING**: Comprehensive error handling with user-friendly messages and solution suggestions
* **RETRY LOGIC**: Automatic exponential backoff retry for transient API failures improves reliability
* **ENHANCED VALIDATION**: YouTube-specific parameter validation prevents common user errors

### Performance Enhancements  
* **BATCH OPERATIONS**: New high-performance functions for bulk data retrieval:
  - `get_videos_batch()`: Process up to 50 videos per API call (50x more efficient)
  - `get_channels_batch()`: Bulk channel statistics retrieval
  - `get_playlists_batch()`: Efficient playlist information fetching
* **RESPONSE CACHING**: Optional caching for static data (video categories, regions, languages) reduces quota usage
* **HELPER FUNCTIONS**: High-level convenience functions for common tasks:
  - `analyze_channel()`: Comprehensive channel analysis
  - `compare_channels()`: Multi-channel comparison
  - `bulk_video_analysis()`: Performance benchmarking across video sets

### Extended API Coverage
* **NEW ENDPOINTS**: Support for previously missing YouTube API endpoints:
  - `get_live_streams()`: Live broadcast and premiere information
  - `get_video_thumbnails()`: Thumbnail URLs and metadata
  - `get_channel_sections()`: Channel sections and featured content
  - `search_shorts()`: YouTube Shorts-specific search

* **DOCUMENTATION**: Comprehensive documentation with examples for all new functions
* **DEPENDENCIES**: Added `digest` package for caching functionality
* **CONSISTENCY**: Standardized patterns across all 65+ R functions

### API Efficiency Improvements
* **QUOTA SAVINGS**: Batch operations reduce API quota usage by up to 50x for bulk operations
* **SMART CACHING**: Automatic caching of static data prevents redundant API calls
* **RATE LIMITING**: Built-in delays and retry logic prevent quota exhaustion

# version 1.1.1

## Bug Fixes and Improvements

This patch release addresses several critical bugs and improves documentation:

### Critical Bug Fixes
* **PAGINATION**: Fixed `get_comment_threads()` pagination bug where comments were duplicated instead of fetching unique results when `max_results > 100` (issue #107)
* **PLAYLIST ITEMS**: Fixed `get_playlist_items()` returning only metadata instead of actual video items (issue #95)
* **CHANNEL VIDEOS**: Fixed `list_channel_videos()` returning only pageInfo instead of video details (issue #88)
* **AUTO-GENERATED CHANNELS**: Improved error handling for YouTube auto-generated channels (music topics, etc.) with helpful guidance to use `yt_search()` instead (issue #118)

### Documentation Improvements
* **VIDEO DETAILS**: Added comprehensive examples for extracting specific fields from `get_video_details()` including Shiny application usage (issue #87)
* **UNLISTED VIDEOS**: Documented OAuth authentication requirement for accessing unlisted video statistics (issue #80)
* **API REFERENCE**: Fixed incorrect API documentation URL in `get_playlist_items()`

### Under the Hood
* Standardized pagination patterns across all functions following `yt_search.R` approach
* Improved error handling with better user guidance

* Added support for API key authentication with two new exported functions, `yt_get_key()` and `yt_set_key()`, and a new `auth` argument to the internal function `tuber_GET()`. Users can now pass `auth = "key"` to any function that uses `tuber_GET()` to enable API key authentication. The behavior of `tuber_GET()` remains unchanged when using the new default, `auth = "token"`, which avoids breaking changes to previously written code (@gvelasq, #117).

# version 0.9.9

* added functionality like upload_video etc. see https://github.com/gojiplus/tuber/commit/2cf53c50e9079af0f6b1a478698d0bda15f4c5e0
