- Introduced `usage-statistics-enabled` configuration to control in-memory usage aggregation.
- Updated API to include handlers for managing `usage-statistics-enabled` and `logging-to-file` options.
- Enhanced `watcher` to log changes to both configurations dynamically.
- Updated documentation and examples to reflect new configuration options.
- Added references to EasyCLI and Cli-Proxy-API-Management-Center in both English and Chinese README files.
- Updated SDK documentation section with new links for access, watcher, and custom provider examples.
- Introduced a keep-alive endpoint to monitor service activity.
- Added timeout-specific shutdown functionality when the endpoint is idle.
- Implemented password-protected access for the keep-alive endpoint.
- Updated server startup to support configurable keep-alive options.
- Implemented a global logger with structured formatting for consistent log output.
- Added support for rotating log files using Lumberjack.
- Integrated new logging functionality with Gin HTTP server for unified log handling.
- Replaced direct `log.Info` calls with `fmt.Printf` in non-critical paths to simplify core functionality.
- Added `label` field to the management API for better token identification.
- Updated request payload and validation logic to include `label` as a required field.
- Adjusted documentation (`MANAGEMENT_API.md`, `MANAGEMENT_API_CN.md`) to reflect changes.
- Added extensive SDK usage guides for `cliproxy`, `sdk/access`, and watcher integration.
- Introduced `--password` flag for specifying local management access passwords.
- Enhanced management API with local password checks to secure localhost requests.
- Updated documentation to reflect the new password functionality.
- Eliminated `allow-localhost-unauthenticated` configuration field and its usage.
- Removed associated management API handlers and middleware logic.
- Simplified authentication middleware by deprecating localhost-specific checks.
- Changed log timestamp format in `request_logger.go` to align with ISO standards for improved readability.
- Removed deprecated `force-gpt-5-codex` handlers from management API.
- Eliminated the deprecated `force-gpt-5-codex` configuration option from all configs, handlers, and documentation.
- Updated examples and README files to reflect the removal.
- Streamlined related code by dropping unused fields and logging.
- Updated all authentication commands to use `fmt` instead of `log` for errors, info, and success messages.
- Ensured message formatting aligns across commands for consistent user experience.
- Introduced `POST /gemini-web-token` endpoint to save Gemini Web cookies directly.
- Added payload validation and hashed-based file naming for persistence.
- Updated documentation to reflect the new management API functionality.
- Removed `FileStore` in favor of the new `FileTokenStore`.
- Centralized auth JSON handling and token operations through `FileTokenStore`.
- Updated all components to utilize `FileTokenStore` for consistent storage operations.
- Introduced `SetBaseDir` and directory locking mechanisms for flexible configurations.
- Enhanced metadata management, including path resolution and deep JSON comparisons.
- Introduced `RegisterTokenStore` and `GetTokenStore` to centralize token store access.
- Replaced direct file operations with a unified token persistence API.
- Updated all components to use the shared token store for consistent behavior.
- Improved logging for token save operations to include file paths.
- 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.
- Adjusted stream handling to skip "[DONE]" chunks.
- Ensured "data:" prefix is trimmed for non-prefixed input in translation.
- Removed `session_id` from request bodies before processing.
