Release Notes: New modules in this release include tracker.module, weblogs.module, and taxonomy.module. Both the node system and the user system have been reworked. The user module now allows for user-authentication through XML-RPC. The node module now supports content versioning and has improved usability. The blogger API is supported. A great number of further enhancements were also added.
Release Notes: When pages are cached for anonymous users (either by Drupal or by an external system), the form state may leak between anonymous users. As a consequence, there is a chance that interim form input recorded for one anonymous user (which may include sensitive or private information, depending on the nature of the form) will be disclosed to other users interacting with the same form at the same time. This especially affects multi-step Ajax forms because the window of opportunity (i.e., the time span between user input and final form submission) is indeterminable. This release fixes this.
Release Notes: Multiple vulnerabilities were fixed related to optimistic cross-site request forgery protection in the Form API validation, multiple vulnerabilities due to weakness in pseudorandom number generation using mt_rand() which affected the Form API, OpenID and random password generation, code execution prevention using the files directory .htaccess for Apache, access bypassing for security token validation, cross-site scripting in the image and color modules, and an open redirect in the overlay module.
Release Notes: This release fixes multiple vulnerabilities due to optimistic cross-site request forgery protection, multiple vulnerabilities due to weakness in pseudorandom number generation using mt_rand(), code execution prevention, and access bypassing. To fix the code execution prevention vulnerability on existing Apache installations also requires changes to your site's .htaccess files in the files directories.
Release Notes: Resolves a vulnerability that allows blocked users to appear in user search results, even when the search results are viewed by unprivileged users. An arbitrary PHP code execution vulnerability was also fixed in the file upload module.
Release Notes: Resolves security issues with an access bypass in the user and upload modules as well as arbitrary PHP code execution in the file upload module.
