v1.2.0

• Fix: cached false values are now correctly returned instead of being treated as cache misses
• Fix: deleteMultiple() no longer returns false when deleting non-existent keys (PSR-16 compliance)
• Fix: delete(), has(), clear() now properly catch RedisException and respect error modes
• Change: clear() uses SCAN instead of KEYS to avoid blocking Redis in production
• Change: manual serialization (SERIALIZER_NONE) replaces Redis built-in serializer
• Add: configurable key prefix via constructor ($prefix, default cache:)
