Simplified from `Client[TEvents, TMetadata]` to simple `Client` +- **Updated API** - Changed from `NewClient[T, M](config)` to `NewClient(config)` +- **Performance optimizations** - Added object pooling and pre-allocated platform objects +- **Simplified codebase** - Removed type complexity while maintaining functionality +- **Updated all documentation** - Removed generic examples and type-safe usage sections + ### Adapter Naming Refactor + - Renamed `DefaultHTTPAdapter` to `NetHTTPAdapter` for better Go conventions - Updated constructor: `NewDefaultHTTPAdapter()` → `NewNetHTTPAdapter()` ### Timer Behavior Enhancement + - Timer now only starts when first new event is tracked, not during SDK initialization - Timer automatically stops when queue becomes empty to save CPU cycles and reduce log noise - If persisted events exist, they remain in queue until a new event triggers the timer - Maintains same API while improving efficiency for apps with persisted events ### Graceful Shutdown Enhancement + - Added `StopWithoutFlush()` and `DisposeWithoutFlush()` methods for graceful shutdown without flushing events - Fixed playground client exit behavior to persist events without sending to server ### Error Handling Improvement + - Changed `NewClient()` to return `(*Client, error)` instead of panicking on invalid configuration - Libraries should never panic as it crashes the entire application and can't be handled by users - Configuration validation errors are now properly returnable and handleable ### Go Version Upgrade + - Upgraded from Go 1.23 to Go 1.25 - Replaced manual `wg.Add(1)` + `go func()` + `defer wg.Done()` with cleaner `wg.Go()` method - Reduces boilerplate code and eliminates WaitGroup management errors @@ -36,28 +48,28 @@ This
