* Add support for more package managers by bind mounting their directories
* Support snapshots without dedicated overlay [boo#1183539], [bsc#1183539]
* Link RPM database correctly with older zypper versions [boo#1183521]
* Don't discard manual changes in fstab [boo#1183856]

Version 3.2.2
* Don't skip patches with rebootSuggested flag

Version 3.2.1
* t-u: Forward --quiet option to tukit
* Regression: Add /opt as bind mount into update environment

  line
* Fix /etc syncing with --drop-if-no-change

Version 3.2.0
* tukit: Add new command 'callext' to execute an application while the
  snapshot is mounted. '{}' as a parameter will be replaced with the path
  of the bind mount.
* Fix --drop-if-no-change [boo#1182525]
* Check whether self-updated version is executable (e.g. on noexec /tmp)
  [bsc#1173842]
* Fix overlay synchronisation with SELinux (again)
* Always overwrite supplemental files (e.g. for network configuration)
  even if they exist in the snapshot already [boo#1182544]
* Improve logging and error messages

Version 3.1.4
* SELinux: Fix syncing of SELinux attributes when using overlays
* SELinux: Tag the overlay directory itself (again)

Version 3.1.3
* Fix overlay syncing on SELinux systems
* Fix resuming transactions where the parent does not exist any more

Version 3.1.2
* libtukit: Report when application was terminated due to a signal, and
  return the signal number as a return value. This will cause the
  transaction to be aborted when called via `execute`.
* libtukit: Set PATH variable for internal commands to fixed value to
  find the helper applications, as in some environments such as PolicyKit
  PATH wouldn't be set.
* Fix compiler warnings

Version 3.1.1
* Fix hang in tukit on aarch64 [bsc#1181844]
* Prevent deletion of snapshots when resuming a snapshot where no transaction
  is open
* Make tukit work in non-dbus environments [boo#1181934]

Version 3.1.0
* t-u: Support installing RPMs from the user's directory again
* Adapt selfupdate to new packaging
* Implement signal handling
* Remove empty text files

Version 3.0.0
* This release changes the internal structure, but should be identical to the
  previous release feature wise.
* Major parts of the previous Bash only application have been rewritten in C++
  with the goal to provide an API around transactions; the transactional-update
  script is using that new interface internally already, however the API should
  be considered experimental for now - if you are interested to use it, please
  notify us in https://github.com/openSUSE/transactional-update/issues/52
* A new tool called "tukit" is providing a Shell wrapper for above
  functionality. Please also consider it experimental for now, the commands may
  still change.
* Bugfixes:
  * Implement support for system offline update [boo#1180808]
  * Add statistics files to update environment [boo#1173282]

Version 2.28.3
* SELinux: Make synchronisation work for both pre-SELinux snapshots and later
  snapshots; SELinux support should be ready for most tasks now.

Version 2.25.1

* Use log_{info,error} for more messages to avoid messing up Salt logs

Version 2.25
* Reduce number of overlays:
  Instead of using transparent overlays for all previous layers only add the
  previous snapshot's overlay; this will greatly reduce the number of overlays
  while still making sure that /etc changes in the running system will be
  visible in the next snapshot
* When using --drop-if-no-change synchronize potential /etc changes with
  running system
* Exclude all non-root-fs mounts from inotify watcher

Version 2.24.1

Version 2.24
* Add partial SELinux support

Version 2.23

  without changes more reliably (e.g. when installing an already installed
  package)
* Update the manpage accordingly
* Get rid of Perl dependency
* Building documentation requires Python 3 now
* Bugfixes:

Version 2.12
* Implements support for needs-restart (Fate#326451)
* Adds easy rollback to last known working snapshot by using "last"
  as the snapshot number
* Migrate /etc/fstab.sys entires to /etc/fstab for systemd being
  able to create mount units; this will prevent errors on unmount
  during shutdown for /var and /etc
* Remove implicit --no-allow-vendor-change - this option can be
  configured in zypper's configuration file now
* Add support for mounting the /etc overlay file system as a systemd
  unit in /etc/fstab on a read-only system (replacing /etc/fstab.sys
  in the long run)
* Various bugfixes:
  * Only remove /etc overlays on read-only root file systems
    [boo#1122455]
  * Disable "Persistent" flag in systemd timer unit to prevent
    updates during or immediately after the boot phase

  * Each root file system snapshot now has a dedicated /etc overlay in
    /var/lib/snapshots/<snapshot number>/etc
  * Changes in older snapshots will be visible in newer snapshots (if
    the file hasn't been changed in both snapshots), but not the other
    way around; this makes it possible to roll back to a previous
    snapshot even if the configuration is broken
  * The /etc state of the oldest active snapshot will be synchronized
    into the new snapshot to prevent ever growing overlays
  * Removed creation of /etc backup snapshots
  * Removed complex overlayfs cleanup handling during dracut early boot;

Version 2.6
* Add --interactive and --non-interactive options to change the default
  interactivity for zypper calls. For previously non-interactive calls (e.g.
  dup) these options makes it possible to pick the correct solution in case
  of conflicts or make sure that a script will never be stuck at an input
  prompt.
* Add kured reboot support
* Tries to clean up temporary files and mount points if transactional-update
  quits unexpectedly
* Remove trancactional-update-helper (replaced by zypper options)

Version 2.5
* Support for overlayfs attributes like trusted.overlay.opaque - this will
  avoid disappearing configuration files on system updates
