Flint v0.2.1

Flint v0.2.1

Flint v0.2.1 hardens the embedded persistent rate limiter with performance mode, async Python wrappers, shared-mode improvements, formal docs, and updated full Criterion benchmark numbers.

Highlights

• Persistent embedded rate limiting without Redis, broker, or daemon.
• sync="always" for safest persistence and sync="batch" for higher throughput.
• Explicit flush() support in embedded and shared mode.
• Async Python wrapper methods: acheck, aallow, astatus, alist, aflush, and more.
• FastAPI middleware offloads limiter checks away from the event loop.
• Shared HTTP server exposes /v1/log/flush.
• Formal docs added for Python usage, CLI, security, storage format, FastAPI, shared mode, and release flow.
