Laravel Idempotency Laravel Package

Added

• IdempotentReplay event, fired whenever a stored response is replayed — useful for metrics on how many retries you are absorbing.
• Per-route retention: pass a TTL (seconds) as a middleware parameter, ->middleware('idempotency:3600'), overriding the configured default.

First stable release.

Safe request retries for Laravel APIs via the Idempotency-Key header:

• idempotency middleware that replays the original response for a repeated key and serialises concurrent duplicates with an atomic lock.
• Request fingerprinting rejects a key reused with a different payload (422).
• Configurable header, guarded methods, retention, lock timeout, key scoping, replayable status codes and persisted headers.
• Cache-backed storage with no migrations.

Requires PHP 8.2+ and Laravel 12.
