+Git 2.30 Release Notes
+Updates since v2.29
+UI, Workflows & Features
+ * Userdiff for PHP update.
+ * Userdiff for Rust update.
+ * Userdiff for CSS update.
+ * The command line completion script (in contrib/) learned that "git
+ stash show" takes the options "git diff" takes.
+ * "git worktree list" now shows if each worktree is locked. This
+ possibly may open us to show other kinds of states in the future.
+ * "git maintenance", an extended big brother of "git gc", continues
+ to evolve.
+ * "git push --force-with-lease[=<ref>]" can easily be misused to lose
+ commits unless the user takes good care of their own "git fetch".
+ A new option "--force-if-includes" attempts to ensure that what is
+ being force-pushed was created after examining the commit at the
+ tip of the remote ref that is about to be force-replaced.
+ * "git clone" learned clone.defaultremotename configuration variable
+ to customize what nickname to use to call the remote the repository
+ was cloned from.
+ * "git checkout" learned to use checkout.guess configuration variable
+ and enable/disable its "--[no-]guess" option accordingly.
+ * "git resurrect" script (in contrib/) learned that the object names
+ may be longer than 40-hex depending on the hash function in use.
+ * "git diff A...B" learned "git diff --merge-base A B", which is a
+ longer short-hand to say the same thing.
+ * A sample 'push-to-checkout' hook, that performs the same as
+ what the built-in default action does, has been added.
+ * "git diff" family of commands learned the "-I<regex>" option to
+ ignore hunks whose changed lines all match the given pattern.
+ * The userdiff pattern learned to identify the function definition in
+ POSIX shells and bash.
+ * "git checkout-index" did not consistently signal an error with its
+ exit status, but now it does.
+ * A commit and tag object may have CR at the end of each and
+ every line (you can create such an object with hash-object or
+ using --cleanup=verbatim to decline the default clean-up
+ action), but it would make it impossible to have a blank line
+ to separate the title from the body of the message. We are now
+ more lenient and accept a line with lone CR on it as a blank line,
+ too.
+ * Exit codes from "git remote add" etc. were not usable by scripted
+ callers, but now they are.
+ * Zsh autocompletion (in contrib/) update.
+Performance, Internal Implementation, Development Support etc.
+ * Use "git archive" more to produce the release tarball.
+ * GitHub Actions automated test improvement to skip tests on a tree
+ identical to what has already been tested.
+ * Test-coverage for running commit-graph task "git maintenance" has
+ been extended.
+ * Our test scripts can be told to run only individual pieces while
+ skipping others with the "--run=..." option; they were taught to
+ take a substring of test title, in addition to numbers, to name the
+ test pieces to run.
+ * Adjust tests so that they won't scream when the default initial
+ branch name is changed to 'main'.
+ * Rewriting "git bisect" in C continues.
+ * More preliminary tests have been added to document desired outcome
+ of various "directory rename" situations.
+ * Micro clean-up of a couple of test scripts.
+ * "git diff" and other commands that share the same machinery to
+ compare with working tree files have been taught to take advantage
+ of the fsmonitor data when available.
+ * The code to detect premature EOF in the sideband demultiplexer has
+ been cleaned up.
+ * Test scripts are being prepared to transition of the default branch
+ name to 'main'.
+Fixes since v2.29
+ * In 2.29, "--committer-date-is-author-date" option of "rebase" and
+ "am" subcommands lost the e-mail address by mistake, which has been
+ corrected.
+ (merge 5f35edd9d7 jk/committer-date-is-author-date-fix later to maint).
+ * "git checkout -p A...B [-- <path>]" did not work, even though the
+ same command without "-p" correctly used the merge-base between
+ commits A and B.
+ (merge 35166b1fb5 dl/checkout-p-merge-base later to maint).
+ * The side-band status report can be sent at the same time as the
+ primary payload multiplexed, but the demultiplexer on the receiving
+ end incorrectly split a single status report into two, which has
+ been corrected.
+ (merge 712b0377db js/avoid-split-sideband-message later to maint).
+ * "git fast-import" wasted a lot of memory when many marks were in use.
+ (merge 3f018ec716 jk/fast-import-marks-alloc-fix later to maint).
+ * A test helper "test_cmp A B" was taught to diagnose missing files A
+ or B as a bug in test, but some tests legitimately wanted to notice
+ a failure to even create file B as an error, in addition to leaving
+ the expected result in it, and were misdiagnosed as a bug. This
+ has been corrected.
+ (merge 262d5ad5a5 es/test-cmp-typocatcher later to maint).
+ * When "git commit-graph" detects the same commit recorded more than
+ once while it is merging the layers, it used to die. The code now
+ ignores all but one of them and continues.
+ (merge 85102ac71b ds/commit-graph-merging-fix later to maint).
+ * The meaning of a Signed-off-by trailer can vary from project to
+ project; this and also what it means to this project has been
+ clarified in the documentation.
+ (merge 3abd4a67d9 bk/sob-dco later to maint).
+ * "git credential' didn't honor the core.askPass configuration
+ variable (among other things), which has been corrected.
+ (merge 567ad2c0f9 tk/credential-config later to maint).
+ * Dev support to catch a tentative definition of a variable in our C
+ code as an error.
+ (merge 5539183622 jk/no-common later to maint).
+ * "git rebase --rebase-merges" did not correctly pass --gpg-sign
+ command line option to underlying "git merge" when replaying a merge
+ using non-default merge strategy or when replaying an octopus merge
+ (because replaying a two-head merge with the default strategy was
+ done in a separate codepath, the problem did not trigger for most
+ users), which has been corrected.
+ (merge 43ad4f2eca sc/sequencer-gpg-octopus later to maint).
+ * "git apply -R" did not handle patches that touch the same path
+ twice correctly, which has been corrected. This is most relevant
+ in a patch that changes a path from a regular file to a symbolic
+ link (and vice versa).
+ (merge b0f266de11 jt/apply-reverse-twice later to maint).
+ * A recent oid->hash conversion missed one spot, breaking "git svn".
+ (merge 03bb366de4 bc/svn-hash-oid-fix later to maint).
+ * The documentation on the "--abbrev=<n>" option did not say the
+ output may be longer than "<n>" hexdigits, which has been
+ clarified.
+ (merge cda34e0d0c jc/abbrev-doc later to maint).
+ * "git p4" now honors init.defaultBranch configuration.
+ (merge 1b09d1917f js/p4-default-branch later to maint).
+ * Recently the format of an internal state file "rebase -i" uses has
+ been tightened up for consistency, which would hurt those who start
+ "rebase -i" with old git and then continue with new git. Loosen
+ the reader side a bit (which we may want to tighten again in a year
+ or so).
+ (merge c779386182 jc/sequencer-stopped-sha-simplify later to maint).
+ * Other code cleanup, docfix, build fix, etc.
+ (merge 3e0a5dc9af cc/doc-filter-branch-typofix later to maint).
+ (merge 32c83afc2c cw/ci-ghwf-check-ws-errors later to maint).
+ (merge 5eb2ed691b rs/tighten-callers-of-deref-tag later to maint).
