[2.0.1] - 2025-04-08

JsonDumpsEncoder now handles NaTType (pandas NaT) without throwing TypeError
CORS Access-Control-Allow-Origin now defaults to "*" instead of echoing the request Origin header (security fix)
RbacUser.can() correctly handles empty permission list
Fixed race condition in aio_pool.py when task queue is full under high concurrency

Refactored config.py — get_config() now consistently returns None instead of raising on missing optional keys (use default parameter for fallback)
Upgraded minimum Python version from 3.9 to 3.11
pyproject.toml dependencies cleaned up — core dependencies slimmed down; pandas/numpy/matplotlib/opencv moved to [project.optional-dependencies]

Deprecated web/legacy_session.py — use JWT-based @auth_token decorator instead

Swagger UI auto-generation (ApplicationSwagger) — fully inferred from handler route patterns and decorators
Redis StreamActor — consumer-group-based message processing with automatic zombie task recovery
ParamAwareUIModule — async data pre-loading for Tornado UIModules
RBAC with dynamic rules — rules are serialized Python classes stored in DB, supporting time-based, IP-based, and custom rule chains
Snowflake ID generator (snow_id.py) — thread-safe, no external dependency, 10K+ IDs/sec
Auto-loading handlers — Application.load_handlers() discovers all handlers in a package via route_pattern attribute
BaseX encoder/decoder (encoder.py) — auto-detect Base16/32/64/85 + zlib decompression
Async DB engine — SQLAlchemy async session factory with aiomysql / aiosqlite support
Task service with daemonization — TaskService with PID file, start/stop/status commands, and graceful shutdown
5 complete examples under examples/ — HelloWorld, background tasks, Redis streams, scheduled services, model generation
pytest test suite — unit tests (mocked) + integration tests for DB, Redis, RBAC

Complete project restructuring: introduced web/, core/, db/, rbac/, util/, service/ package layout
Application now inherits from tornado.web.Application — backward-incompatible refactor from v1.x
RequestHandler.response_ok() and response_error() now use JsonDumpsEncoder by default
Logging system rewritten — supports rotating file handlers, per-module loggers, console output
