This new version, still tagged as beta,  improves the PHP 5.3.0 support (not handled by version 3.0.19 stable).

We can discover a new solution to optimize cache by enabling the new apc.lazy_classes and  apc.lazy_functions options. To be tested. It uses a differed load during the call rather than during the load.

As always

yum --enablerepo=remi update php-pecl-apc

Don't forget to install the control pannel (file /usr/share/doc/php-pecl-apc-3.1.3p1/apc.php) which allow check the cache performance and to tune the configuration (/etc/php.d/apc.ini)

A small problem with one of the tests, to be followed on PECL::Bug #16793
