This new version, still tagged as beta,  improves the PHP 5.3 support. It also fixes various bugs, and a potential security issue.

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-3.1.4/apc.php) which allow check the cache performance and to tune the configuration (/etc/php.d/apc.ini).

This extension, maintained by main PHP developers, will probably include in next PHP major version (5.4 ?).
