+AppArmor 4.0.3 was released 2024-11-??.
+
+# Introduction
+
+AppArmor 4.0.4 is a bug fix 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).
+
+# 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
