  script_tag(name:"insight", value:"This update for git fixes the following issues:

     Update from version 2.26.2 to version 2.31.1 (jsc#SLE-18152)

     Security fixes:

  - CVE-2021-21300: On case-insensitive file systems with support for
       symbolic links, if Git is configured globally to apply delay-capable
       clean/smudge filters (such as Git LFS), Git could run remote code during
       a clone. (bsc#1183026)

     Non security changes:

  - Add `sysusers` file to create `git-daemon` user.

  - Remove `perl-base` and `openssh-server` dependency on `git-core`and
       provide a `perl-Git` package. (jsc#SLE-17838)

  - `fsmonitor` bug fixes

  - Fix `git bisect` to take an annotated tag as a good/bad endpoint

  - Fix a corner case in `git mv` on case insensitive systems

  - Require only `openssh-clients` where possible (like Tumbleweed or SUSE
       Linux Enterprise  = 15 SP3). (bsc#1183580)

  - Drop `rsync` requirement, not necessary anymore.

  - Use of `pack-redundant` command is discouraged and will trigger a
       warning. The replacement is `repack -d`.

  - The `--format=%(trailers)` mechanism gets enhanced to make it easier to
       design output for machine consumption.

  - No longer give message to choose between rebase or merge upon pull if
       the history `fast-forwards`.

  - The configuration variable `core.abbrev` can be set to `no` to force no
       abbreviation regardless of the hash algorithm

  - `git rev-parse` can be explicitly told to give output as absolute or
       relative path with the `--path-format=(absoluterelative)` option.

  - Bash completion update to make it easier for end-users to add completion
       for their custom `git` subcommands.

  - `git maintenance` learned to drive scheduled maintenance on platforms
       whose native scheduling methods are not &#x27 cron&#x27.

  - After expiring a reflog and making a single commit, the reflog for the
       branch would record a single entry that knows both `@{0}` and `@{1}`,
       but we failed to answer 'what commit were we on?', i.e. `@{1}`

  - `git bundle` learns `--stdin` option to read its refs from the standard
       input. Also, it now does not lose refs when they point at the same
       object.

  - `git log` learned a new `--diff-merges= how ` option.

  - `git ls-files` can and does show multiple entries when the index is
       unmerged, which is a source for confusion unless `-s/-u` option is in
       use.  A new option `--deduplicate` has been introduced.

  - `git worktree list` now annotates worktrees as prunable, shows locked
       and prunable att ...
