Release 4.6.5

• Rework soft-reboot support introduced in 4.6.0:
  • On transactional systems with systemd 254 the system could hang with with a soft-reboot, as /var and /etc have to be mounted in /run/nextroot explicitly. As a soft-reboot can also be triggered by an admin the mounting of the corresponding mount points was moved to a systemd service to be independent of t-u itself.
  • Support for systemd 255
  • Don't decrease reboot level on multiple commands
  • Various other bugfixes
  • soft-reboot support is disabled by default now to gather more feedback
• libtukit: Fix kexec reboot method to boot kernel / initrd of next snapshot
• tukit: Don't clone lock file handle on exec [boo#1222411]
• t-u: Always use zypper of installed system [bsc#1221346]
• t-u: Remove remaining telemetrics references

Release v4.1.7

• Always use zypper of installed system [bsc#1221346]

Release 4.6.0

• tukit / t-u: Implement support for systemd soft-reboot, but needs package manager support (provided by zypp-boot-plugin on openSUSE) to determine which kind of reboot is required; the minimally required reboot method (soft-reboot, kexec, full reboot) will be used automatically if enabled (see tukit.conf).
  This deprecates the "kexec" reboot method in favor of automatic selection.
• tukit: Determine D-Bus availability via system socket instead of brute force
• tukit: Don't ignore return status of snapper - plugins can return an error code now where tukit has to fail [gh##118] / [poo#127169]
• tukit: Remove BTRFS dependencies in snapper backend, user snapper for for everything directly. In theory this should support further file systems such as bcachefs if they follow the same layout (untested).
• t-u: Add safety net before deleting overlays [boo#1217416]
• t-u: Remove telemetry support, the required packages haven't been in the repository for quite some time as they were abandoned upstream.
• doc: Document option to use names in BINDDIRS array
• doc: Mention tukit.conf in t-u man page
• doc: Link Reboot.hpp as an officially supported API on the main page
• Code cleanup

Release 4.5.0

• libtukit: Use permissions of real /etc when creating overlay [bsc#1215878]
• libtukit, tukit: Support "rollback" via library now
• tukitd: Implement Snapshot delete and rollback methods
• tukit: Check for missing arguments with "close" and "abort" commands
• t-u: Warn user when using "kdump" if it isn't configured to avoid confusion with "setup-kdump" [boo#1215725]
• t-u: Abort if mkdumprd run is not successful
• t-u: Use defaut from config file if t-u is called without arguments [gh##101]
• Improved README.md [gh##59] and API docs
• Code cleanup

Release 4.1.6

The 4.1.x series is in maintenance mode.

Version 4.1.6 release contains the following change:

• Use permissions of real /etc when creating overlay

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
