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

Release 4.0.1

• create_dirs_from_rpmdb: Just warn if no default SELinux context found
  [#88], [bsc#1188215]
• create_dirs_from_rpmdb: Don't update the rpmdb cookie on failure
  [#88]
• Handle directories owned by multiple packages
  [#90], [bsc#1188215]

Release 4.0.0

This new major release adds an official C++ and C API along with a D-Bus interface. The release is API, but not ABI compatible with previous releases; existing applications will have to be recompiled against this new version.

The detailed Changelog compared to version 3.6.2 (see the NEWS file for changes since the last release candidate):

• Implement C++ interface for listing Snapshots
• Implement Reboot interface
• Introduces a C binding via libtukit.h.
• Introduces a D-Bus service to access the libtukit API via the org.opensuse.tukit.Transaction and org.opensuse.tukit.Snapshot interfaces
• Use separate mount namespace for chroot, allowing overwriting the bind mounts from the update environment - this could have lead to data loss of the bind mount previously
• t-u: Rework --quiet handling to make sure no output is shown even in error cases; this is necessary for automation, e.g. with Salt.
• tukit: Allow storing command output into variable by introducing a new optional parameter for "execute" and "callExt".
• Replace multiple and non-standalone occurenses of {} in "callExt" argument.
• Split transactional-update.timer into transactional-update.timer and transactional-update-cleanup.timer; the later will clean up old snapshots even when the system does not do automatic updates.
• tukit: Remove legacy alias "setDiscard" for "setDiscardIfUnchanged".
• Throw exception if snapshot is not found.
• Add output of tukit commands to log file
• create_dirs_from_rpmdb: set SELinux file context of missing directories [gh##84], [bsc#1197242]
• Fix broken logrotate due to typo in config file [gh##87]
• create_dirs_from_rpmdb: Fix handling return code of create_dirs() [gh##86]
• Fix compilation error with GCC12 [boo#1194876]
• Fix wrong sort order in status command [gh##80]
• Fix bug when using --continue on old snapshots
• Fix various compiler warnings
• Code cleanup

Prerelease 4.0.0 RC2

The 4.0.0 release is API, but not ABI compatible with previous releases; existing applications will have to be recompiled against this new version.

Major features:

• Introduces a D-Bus service to access the libtukit API via the org.opensuse.tukit.Transaction interface
• Introduces a C binding via libtukit.h.

Other changes:

• t-u: Rework --quiet handling to make sure no output is shown even in error cases; this is necessary for automation, e.g. with Salt. [gh##73]
• tukit: Allow storing command output into variable by introducing a new optional parameter for "execute" and "callExt".
• Replace multiple and non-standalone occurenses of {} in "callExt" argument.
• Split transactional-update.timer into transactional-update.timer and transactional-update-cleanup.timer; the later will clean up old snapshots even when the system does not do automatic updates.
• tukit: Remove legacy alias "setDiscard" for "setDiscardIfUnchanged".
• Throw exception if snapshot is not found.
• Fix various compiler warnings

Changes in RC2:

• Fix missing prompt in "shell" command [bsc#1196580]
• Add output of tukit commands to log file
• Fix compilation error with GCC12 [boo#1194876]
• Fixed (non-critical) security review comments [boo#1196149]
• Fixed selfupdate
• Code cleanup

Release Version 3.6.2

• Bind mount root file system snapshot on itself, this makes the temporary directory in /tmp unnecessary; also fixes [boo#1188110] to return the correct snapshot's working directory via API call.
• Use separate mount namespace for transactional-update; this should fix several applications that fail to run if a mount point has the 'unbindable' mount flag set

Release Version 3.6.1

• Fix rsyncing /etc into the running system with --drop-if-no-change [bsc#1192242]
