Recent releases

Release Notes: This release includes a bugfix and enhancements to the policy editor. TOMOYO 2.3 (Linux 2.6.36) and later appeared to have problems in handling mount permission checks. When applying the fix, you might need redefining policies. A patch for TOMOYO 2.5 will be included in Linux 3.4. Regarding ccs-tools, the number of selected items will now be displayed in the policy editor.

          Release Notes: Several bugs were fixed. A new feature to protect the Android environment from privilege escalation was added. Support for packed policy format was added.

          It is very important to submit releases for tomoyo-2.x here on freshmeat, too! Either there should be another freshmeat project or the tomoyo-2.x releases should be announced right here. Missing this made booting my linux-2.6.36 kernel impossible after new changes!
