The [migration guide][1] includes information about changes from version 5.4; a detailed list can be found in the [PHP Changelog][2]. The APC package will be replaced by [APCu][3]. APCu only provides user data caching. For opcode caching use the new [opcache][4] extension. Alternatively we provide a development version of [XCache][5] which includes both, an opcode and user data cache. Most applications will run without modifications, but watch out for [deprecation warnings][6] that fill up your log files.
