# Release Notes:

  This BOA release includes several important system upgrades and bug fixes.

  All supported Aegir platforms have been updated with latest Drupal cores.

  This version automatically switches all hosted sites to PHP 5.5 on systems
  hosted and managed remotely by Omega8.cc support team, unless you have
  explicitly switched your Octopus instance to use PHP version you prefer.
  Using PHP older than 5.5 is strongly discouraged, for security, stability and
  performance reasons.
