We provide Drupal updates for our clients. Every month we apply the most recent updates to Drupal core and contributed modules. Currently there is no set schedule as to when a minor release of Drupal will be released. For example, a minor release is when Drupal is updated from 7.23 to 7.24. So in November 2013, Drupal 7.24 was released. It contained security fixes. It was recommended to upgrade immediately after reading the security announcement.
On January 3, 2014, Drupal 7.25 was released. This is a maintenance release including bug fixes and small feature improvements only. Drupal 8 is under development and significant new features are only being added to the new Drupal 8 release.
This release was followed quickly by Drupal 7.26 on January 15, 2014. This release fixes security vulnerabilities. Website owners are urged to upgrade immediately. However, some Drupal sites reported a major site slowdown after upgrading to Drupal 7.26 so we have postponed this upgrade.
