managed by puppet from the pool directory.
 * The `pecl_source` parameter for `php::extension` was renamend to
   `source` because it is also useful for PEAR extensions.
   `pecl_source` can still be used but is deprecated and will be
   removed in the next major release.
 * Parameters referring to time in `php::fpm::config` can now be
   specified with units (i.e. `'60s'`, `'1d'`):
   * `emergency_restart_threshold`
   * `emergency_restart_interval`
   * `process_control_timeout`
 * The PEAR version is not independant of `$php::ensure` and can be
   configured with `$php::pear_ensure`
 * Give special thanks to the contributors of this release:
