+AppArmor 3.0.6 was released 2022-07-29.
+
+# Introduction
+
+AppArmor 3.0.6 fixes a couple errors discovered in AppArmor 3.0.5 after release. It is a maintenance release of the user space components of the AppArmor security project. The kernel portion of the project is maintained and pushed separately.
+
+This version of the userspace should work with all kernel versions from
+2.6.15 and later (some earlier version of the kernel if they have the
+apparmor patches applied).
+
+The kernel portion of the project is maintained and pushed separately.
+
+
+# Obtaining the Release
+
+There are two ways to obtain this release either through gitlab or a tarball in launchpad. 
+
+**Important note:** the gitlab release tarballs differ from the launchpad release tarballs. The launchpad release tarball has a couple processing steps already performed:
+
+* libapparmor `autogen.sh` is already done, meaning distros only need to use ./configure in their build setup
+* the docs for everything but libapparmor have already been built

+# Additional Note
+
+There is a semantic change in the 4.8 kernel (commit
+9f834ec18defc369d73ccf9e87a2790bfa05bf46) that affects apparmor policy
+enforcement. Specifically it affects when the m permission bit is
+checked for elf binary executables. Policy and tests within apparmor
+2.12 and later have been updated to support running on pre 4.8 and 4.8+ kernels.
