WARNING this is a beta - NOT a final release

AppArmor 4.0-beta4 was released 2024-04-08.

Introduction

AppArmor 4.0 is a major new release of the AppArmor that is in development.

Apprmor 4.0 is a bridge release between older AppArmor 3.x policy and the newer AppArmor 4 style policy which introduces several new features that are not backwards compatible. As such AppArmor 4.0 will be a short lived release, and will not receive long term support. The following AppArmor 4.1 feature release is planned to be a regular release, please take this into account when including AppArmor 4.0 into a distro release. For questions around compatibility see the compatibility matrix.

These release notes cover changes between AppArmor-4.0~beta3 and AppArmor-4.0~beta4

Notes

  • new dependency build dependency ** autoconf-archive **

This Release contains only Bug Fixes to AppArmor 4.0 beta3

Misc

  • Some features will work with older kernels but many of the features in apparmor 4 with require a development kernel.
  • The kernel portion of the project is maintained and pushed separately.
  • AppArmor 4.0 contains all bug fixes and policy updates from apparmor 3.1
  • Some new features will not be fully supported in some utilities. In these cases it was decided that releasing a new feature earlier had more benefit than delaying it for full utility support. Please see the feature support matrix.
