Changelog

2.0.2

Added

• ObjectCache::flush_group() now delegates to core wp_cache_flush_group() on WP 6.1+ backends that advertise support via wp_cache_supports( 'flush_group' ). The version-sentinel workaround remains the fallback for backends that don't.
• Native-backend read/write paths skip the internal envelope so values are stored raw. Legacy envelopes left behind by the fallback path are unwrapped transparently on read.

Changed

• Minimum WordPress version bumped from 5.0 to 6.1.
• ObjectCache refactored: public methods reduced to thin dispatchers; native and fallback paths split into single-responsibility private helpers.

2.0.1

Fixed

• PHP 8.4 implicit-nullable deprecation on ObjectCache::get().

2.0.0

Changed

• Refactored the library into Contracts / Storage / Support with dependency injection and a full test suite.
• Prefix is now required at construction time (new Cache( 'my_plugin' )); previously a shared duckdev_cache prefix was hardcoded.
• can_cache filter renamed to {prefix}_can_cache.

Fixed

• remember() / forget() now correctly treat a cached 0, '', [], or false as a hit instead of re-running the callback.
