Hello,
the PHP packages for Debian systems were updated to the versions 5.5.35, 5.6.21 and 7.0.6.
Due to popular demand we now also have a PHP 5.3.29 package for Debian 8. Of course we recommend to NOT use it: PHP 5.3 is no more supported since 08/14/2014. Most propably it contains known security issues.
There's a migration guide from PHP 5.3 to 5.4 on the PHP website.
For Debian 6 (Squeeze) this is also the last PHP package update from our side. Debian 6 LTS has reached "end of life" in March 2016, we update our packages for three more months (until end of May).
Best regards
-Klaus Keppler
