2.0.0

Flask API Guard 2.0.0 — guard-core Migration

Flask API Guard is now a thin adapter over guard-core, the framework-agnostic security engine that also powers fastapi-guard and djapi-guard.

What changed

• All security logic moved to guard-core — 17 security checks, 8 handlers, the detection engine, and suspicious pattern analysis now live in a shared engine (guard-core 1.0.0). This package provides only the Flask integration layer via before_request/after_request hooks.
• Dependencies trimmed — core dependencies like cachetools, maxminddb, pydantic, redis, and requests are no longer direct dependencies (they come transitively through guard-core).
• Synchronous API — uses guard_core.sync.* modules for Flask's synchronous request model.

Zero breaking changes to the public API

All existing imports continue to work exactly as before:

from flaskapi_guard.middleware import SecurityMiddleware
from flaskapi_guard import SecurityConfig, SecurityDecorator, IPBanManager, RateLimitManager

**Why v2.0.0**

The major version bump reflects the architectural shift — guard-core is now a required dependency, and internal modules (flaskapi_guard.core.*, flaskapi_guard.handlers.*, flaskapi_guard.detection_engine.*) no longer exist. If you only used the public API, no migration is needed.

**One engine, three frameworks**

All three share the same security engine, ensuring consistent behavior across frameworks.
