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 and supports laminas/laminas-cache v4.

Changed

• Executed apcu_exists during Apcu#getItem since there might be a bug on several systems where success flag of apcu_fetch is set to true for non-existing keys
