Backwards incompatible release (major)

laminas-cache-storage-adapter-memory 3.0.0 is here and finally adds native types everywhere, adds support for psr/cache and psr/simple-cache v2 & v3, supports laminas/laminas-cache v4 and introduces an all new metadata and internal persistence logic.

The Memory adapter had its flaws by juggling with the memory_limit. There were a bunch of issues with that behavior, especially since it is impossible to calculate the exact free memory available. For more details, one can check #57. With this version, we are introducing max_items which limits the amount of items persisted to the Memory adapter (defaults to unlimited). Once the max_items are exceeding, the adapter automatically removes the oldest entries to make room for new items.

Added

• Dedicated Metadata object for Memory#getMetadata
• Adds support for psr/cache and psr/simple-cache v2 & v3
• Memory now allows passing a ClockInterface via its constructor
• MemoryOptions now has max_items configuration to limit the amount of items to be cached. When the limit exceeds, the adapter automatically drops older items

Changed

• Memory adapter now supports per-item TTL and thus, the TTL is calculated on-write rather than on-read
• Memory adapter now supports max_items option which can be used to limit the amount of items persisted to the cache

Removed

• MemoryOptions#setMemoryLimit , there is no replacement. It is recommended to use the max_items option instead
• MemoryOptions#getMemoryLimit, there is no relacement
