Release 4.4.0

• t-u: Introduce setup-fips command [jsc#SMO-194]
• libtukit: Always set a cleanup algorithm for snapshots - when using API, D-Bus interface or tukit the snapshots will be automatically cleaned up by snapper after some time now; in the past only snapshots created by the transactional-update shell script would be cleanup after, and only after a t-u cleanup run.
• tukit: enable kexec's syscall detection feature
• tukit: Don't throw exceptions from the child process after fork
• tukitd: Rename service file to org.opensuse.tukit.service
• tukitd: Allow querying DBus Properties [boo#1214707]
• t-u: Add support for fully written-out update commands
• t-u: Improve detection of existing kernel parameters

Release 4.3.0

• Replace custom tu-rebuild-kdump-initrd with call to mkdumprd (#107).
• Add support for libmount 2.39. The behaviour change was not intended and will be changed in 2.39.1 (see util-linux/util-linux#2326), but it was easy to fix it anyway.
• Honor LIBMOUNT_DEBUG variable for additional output.

Release 4.2.1

• Add backwards compatibility with older snapper releases, otherwise the selfupdate may break if the installed snapper version is too old; requires snapper 0.8.10 as a minimal base (for rollbacks) now.

Release 4.2.0

• Implement "apply" command to switch into new snapshot directly
• Use new snapper functionality to set default snapshot - this makes it possible to execute hooks as requested in [poo#127160], [gh##85] and [gh##105].
• Don't hardcode GRUB2 [gh##85] / [poo#127154]
• Fix cleanup handler
• Fix unmounting temporary mounts
• Prevent loosing track of snapshots in certain rollback scenarios - these would not be marked for deletion otherwise
• Document "notify" reboot method

Release 4.1.5

• Add support for configuration file snippets

Release 4.1.4

This release is an openSUSE Tumbleweed specific bugfix release: A broken %post script of the libfdisk1 package prevented automatic updates, so a workaround is introduced.

Release 4.1.3

• Suppress SELinux relabelling output in quiet mode
• Documentation readability improvements

Release 4.1.2

• Don't try to mount user mounts if they don't exist [boo#1207366]

Release 4.1.1

• Mount user specific binddirs last: Prevously the internal mounts would potentially overwrite user bind mounts [boo#1205011]
• selinux: Relabel shadowed /var files during update to make sure they don't interfere with the update [boo#1205937]
• Clean up /var/lib/overlay more aggressively [boo#1206947]
• tukit: Merge /etc overlay into parent if --discard is used together with --continue - previously the files were incorrectly always merged with the currently running system
• status: do not execute the status command if experimental
• Don't delete created mount point dirs any more
• Small code optimizations

Release 4.1.0

• t-u: Add a setup-kdump command; implements [jsc#PED-1441]
• Add support for ULP (Userspace Live Patching) [jsc#PED-1078]:
  • Export TRANSACTIONAL_UPDATE_ROOT (the path to the snapshot) in the update environment
  • Unfortunately requires a separate bind mount in /tmp again for the update environment, as libpulp has to be able to access the snapshot directly, without it being bind mounted on itself
• Add support for "notify" reboot method for desktop use [gh##93]
• Fix kdump initrd recreation detection; the check was performed in the active snapshot instead of the target snapshot
• Document register command [bsc#1202900]
• Avoid unnecessary snapshots for register command [bsc#1202901]
• Various optimizations for register command
• Remove bogus error message when triggering reboot
• Rework /etc overlay documentation in "The Transactional Update Guide"
• Fix incorrect manpage formatting
• Remove leftover "salt" reboot method in configuration example file
• Replace deprecated std::mem_fn with lambdas
