PHP has been updated to its latest major release 5.4. The upstream

The Suhosin patch and extension have been removed. Learn more about

If you had used the suhosin extension before remove the php-suhosin
package as it is no longer compatible with PHP 5.4.
Note that the extension API has been changed. If you are using any
third party extensions that are not in our repositories, you have to at
least recompile them or update to a compatible version.
The json module is now built into PHP itself. Therefore, remove the
extension=json.so directive from your php.ini file.
The gd extension has been built with webp support using the libvpx
library.
Make sure to merge the changes of php.ini into your local copy; or
probably easier: adjust the new php.ini to your needs. If you any encounter problems using the APC extension you may try the php-xcache package which has been added to the repository.
Last but not least: especially if you are running old scripts, make sure
they do not rely on features like "Safe Mode" or "Magic Quotes". As these
features were removed, an update to PHP 5.4 will result in serious
security holes.
