- Introduced in-memory request statistics aggregation in `LoggerPlugin`.
- Added new structures for detailed metrics collection (e.g., token breakdown, request success/failure).
- Implemented `/usage` management API endpoint for retrieving aggregated statistics.
- Updated management handlers to support the new usage statistics functionality.
- Enhanced documentation to describe the usage metrics API.
The Gemini Web API client logic has been relocated from `internal/client/gemini-web` to a new, more specific `internal/provider/gemini-web` package. This refactoring improves code organization and modularity by better isolating provider-specific implementations.
As a result of this move, the `GeminiWebState` struct and its methods have been exported (capitalized) to make them accessible from the executor. All call sites have been updated to use the new package path and the exported identifiers.
- Added `LoggerPlugin` to log usage metrics for observability.
- Introduced a new `Manager` to handle usage record queuing and plugin registration.
- Integrated new usage reporter and detailed metrics parsing into executors, covering providers like OpenAI, Codex, Claude, and Gemini.
- Improved token usage breakdown across streaming and non-streaming responses.
- Integrated ZSTD decompression via `github.com/klauspost/compress` for responses with "zstd" content-encoding.
- Added helper `hasZSTDEcoding` to detect ZSTD-encoded responses.
- Updated response handling logic to initialize and use a ZSTD decoder when necessary.
refactor(api-handlers): split streaming and non-streaming response handling
- Introduced `handleNonStreamingResponse` for processing non-streaming requests in `ClaudeCodeAPIHandler`.
- Improved code clarity by separating streaming and non-streaming logic.
fix(service): remove redundant token refresh interval assignment logic in `cliproxy` service.
- Added async dispatch loop to `Watcher` for handling incremental `AuthUpdate` with in-memory buffering.
- Improved resilience against high-frequency auth changes by coalescing updates and reducing redundant processing.
- Updated `cliproxy` service to increase auth update queue capacity and optimize backlog consumption.
- Added detailed SDK integration documentation in English and Chinese (`sdk-watcher.md`, `sdk-watcher_CN.md`).
- Added support for incremental auth updates using `AuthUpdate` and `AuthUpdateAction`.
- Integrated `SetAuthUpdateQueue` to propagate updates through a dedicated channel.
- Introduced new methods for handling auth add, modify, and delete actions.
- Updated service to ensure auth update queues are correctly initialized and consumed.
- Improved auth state synchronization across core and file-based clients with real-time updates.
- Refactored redundant auth handling logic for better efficiency and maintainability.
- Introduced dynamic `providerKey` resolution for OpenAI-compatible providers, incorporating attributes like `provider_key` and `compat_name`.
- Implemented upstream model overrides via `resolveUpstreamModel` and `overrideModel` methods in the OpenAI executor.
- Updated registry logic to correctly store provider mappings and register clients using normalized keys.
- Ensured consistency in handling empty or default provider names across components.
- Replaced legacy `api-keys` field with `auth.providers` in configuration, supporting multiple authentication providers including `config-api-key`.
- Added synchronization to maintain compatibility with legacy `api-keys`.
- Updated core components like request handling and middleware to use the new provider system.
- Enhanced management API endpoints for seamless integration with `auth.providers`.
- Renamed constants from uppercase to CamelCase for consistency.
- Replaced redundant file-based auth handling logic with the new `util.CountAuthFiles` helper.
- Fixed various error-handling inconsistencies and enhanced robustness in file operations.
- Streamlined auth client reload logic in server and watcher components.
- Applied minor code readability improvements across multiple packages.
