Hello!

The 3.2 release for the SELinux userspace is now available at:

https://github.com/SELinuxProject/selinux/wiki/Releases

Thanks to all the contributors to this release!

User-visible changes
--------------------

* libsepol implemented a new, more space-efficient form of storing filename
  transitions in the binary policy and reduced the size of the binary policy
  
* libselinux: Use mmap()'ed kernel status page instead of netlink by default.
  See "KERNEL STATUS PAGE" section in avc_init(3) for more details.
  Note: if you need to `umount /sys/fs/selinux` you need to use lazy umount -
  `umount -l /sys/fs/selinux` as the kernel status page /sys/fs/selinux/status
  stays mapped by processes like systemd, dbus, sshd.
  
* Tools using sepolgen, e.g. audit2allow, print extended permissions in
  hexadecimal
  
* sepolgen sorts extended rules like normal ones

* New log callback levels for enforcing and policy load notices -
  SELINUX_POLICYLOAD, SELINUX_SETENFORCE 

* Changed userspace AVC setenforce and policy load messages to audit format.

* matchpathcon converted to selabel_lookup() - no more matchpathcon is
  deprecated warning
  
* libsepol and libsemanage dropped old and deprecated symbols and functions
  libsepol version was bumped to libsepol.so.2
  libsemanage version was bumped to libsemanage.so.2
  
* Release version for the whole project is same as for subcomponents, e.g.
  instead of 20210118 it's 3.2-rc1

* Improved usability of `getseuser`

* Fixed several issues in cil code found by OSS-FUZZ

* `setfiles` doesn't abort on labeling errors

* libsemanage tries to sync data to prevent empty files in SELinux module store

* Improved secilc documentation - fenced code blocks, syntax highlighting, custom
  color theme, ...

* Better error reporting in getconlist


* libsepol implemented a new, more space-efficient form of storing filename

* Release version for the whole project is same as for subcomponents, e.g.
  instead of 20210304 it's 3.2

* Improved man pages

* Bug fixes


Development-relevant changes
----------------------------

* License the CI scripts with a permissive, OSI approved license, such as MIT

* Several CI improvements

* Added configuration to build and run tests in GitHub Actions

* CI contains configuration for a Vagrant virtual machine - instructions on how
  to use it are documented at the beginning of Vagrantfile.
  
* `scripts/release` was improved to be more robust and release a source repository

Packaging-relevant changes
--------------------------

* Both libsepol and libsemanage bumped their soname versions. Especially
libsemanage is linked to shadow-utils and direct update might cause problems to
buildroots. Also SETools needs to be rebuilt against libsepol.so.2

* Source repository snapshot selinux-3.2-rc2.tar.gz is available on the release page

* sestatus is installed as /usr/bin/sestatus by default. Original /usr/sbin/sestatus is
  a relative symlink to the /usr/bin/sestatus.

Issues fixed
