+Git v2.35.1 Release Notes
+=========================
+
+Git 2.35 shipped with a regression that broke use of "rebase" and
+"stash" in a secondary worktree. This maintenance release ought to

+Git 2.36 Release Notes
+======================
+
+Updates since Git 2.35
+----------------------
+
+Backward compatibility warts
+
+ * "git name-rev --stdin" has been deprecated and issues a warning
+ when used; use "git name-rev --annotate-stdin" instead.
+
+
+Note to those who build from the source
+
+ *
+
+
+UI, Workflows & Features
+
+ * Assorted updates to "git cat-file", especially "-h".
+
+ * The command line completion (in contrib/) learns to complete
+ arguments to give to "git sparse-checkout" command.
+
+ * "git log --remerge-diff" shows the difference from mechanical merge
+ result and the result that is actually recorded in a merge commit.
+
+ * "git log" and friends learned an option --exclude-first-parent-only
+ to propagate UNINTERESTING bit down only along the first-parent
+ chain, just like --first-parent option shows commits that lack the
+ UNINTERESTING bit only along the first-parent chain.
+
+ * The command line completion script (in contrib/) learned to
+ complete all Git subcommands, including the ones that are normally
+ hidden, when GIT_COMPLETION_SHOW_ALL_COMMANDS is used.
+
+ * "git branch" learned the "--recurse-submodules" option.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * "git apply" (ab)used the util pointer of the string-list to keep
+ track of how each symbolic link needs to be handled, which has been
+ simplified by using strset.
+
+ * Fix a hand-rolled alloca() imitation that may have violated
+ alignment requirement of data being sorted in compatibility
+ implementation of qsort_s() and stable qsort().
+
+ * Use the parse-options API in "git reflog" command.
+
+ * The conditional inclusion mechanism of configuration files using
+ "[includeIf <condition>]" learns to base its decision on the
+ URL of the remote repository the repository interacts with.
+ (merge 399b198489 jt/conditional-config-on-remote-url later to maint).
+
+ * "git name-rev --stdin" does not behave like usual "--stdin" at
+ all. Start the process of renaming it to "--annotate-stdin".
+ (merge a2585719b3 jc/name-rev-stdin later to maint).
+
+ * "git update-index", "git checkout-index", and "git clean" are
+ taught to work better with the sparse checkout feature.
+
+ * Use an internal call to reset_head() helper function instead of
+ spawning "git checkout" in "rebase", and update code paths that are
+ involved in the change.
+
+
+Fixes since v2.35
+-----------------
+
+ * "rebase" and "stash" in secondary worktrees are broken in
+ Git 2.35.0, which has been corrected.
+
+ * "git pull --rebase" ignored the rebase.autostash configuration
+ variable when the remote history is a descendant of our history,
+ which has been corrected.
+ (merge 3013d98d7a pb/pull-rebase-autostash-fix later to maint).
+
+ * "git update-index --refresh" has been taught to deal better with
+ racy timestamps (just like "git status" already does).
+ (merge 2ede073fd2 ms/update-index-racy later to maint).
+
+ * Avoid tests that are run under GIT_TRACE2 set from failing
+ unnecessarily.
+ (merge 944d808e42 js/test-unset-trace2-parents later to maint).
+
+ * The merge-ort misbehaved when merge.renameLimit configuration is
+ set too low and failed to find all renames.
+ (merge 9ae39fef7f en/merge-ort-restart-optim-fix later to maint).
+
+ * We explain that revs come first before the pathspec among command
+ line arguments, but did not spell out that dashed options come
+ before other args, which has been corrected.
+ (merge c11f95010c tl/doc-cli-options-first later to maint).
+
+ * "git add -p" rewritten in C regressed hunk splitting in some cases,
+ which has been corrected.
+ (merge 7008ddc645 pw/add-p-hunk-split-fix later to maint).
+
+ * "git fetch --negotiate-only" is an internal command used by "git
+ push" to figure out which part of our history is missing from the
+ other side. It should never recurse into submodules even when
+ fetch.recursesubmodules configuration variable is set, nor it
+ should trigger "gc". The code has been tightened up to ensure it
+ only does common ancestry discovery and nothing else.
+ (merge de4eaae63a gc/fetch-negotiate-only-early-return later to maint).
+
+ * The code path that verifies signatures made with ssh were made to
+ work better on a system with CRLF line endings.
+ (merge caeef01ea7 fs/ssh-signing-crlf later to maint).
+
+ * "git sparse-checkout init" failed to write into $GIT_DIR/info
+ directory when the repository was created without one, which has
+ been corrected to auto-create it.
+ (merge 7f44842ac1 jt/sparse-checkout-leading-dir-fix later to maint).
+
+ * Cloning from a repository that does not yet have any branches or
+ tags but has other refs resulted in a "remote transport reported
+ error", which has been corrected.
+ (merge dccea605b6 jt/clone-not-quite-empty later to maint).
+
+ * Mark in various places in the code that the sparse index and the
+ split index features are mutually incompatible.
+ (merge 451b66c533 js/sparse-vs-split-index later to maint).
+
+ * Update the logic to compute alignment requirement for our mem-pool.
+ (merge e38bcc66d8 jc/mem-pool-alignment later to maint).
+
+ * Pick a better random number generator and use it when we prepare
+ temporary filenames.
+ (merge 47efda967c bc/csprng-mktemps later to maint).
+
+ * Update the contributor-facing documents on proposed log messages.
+ (merge cdba0295b0 jc/doc-log-messages later to maint).
+
+ * When "git fetch --prune" failed to prune the refs it wanted to
+ prune, the command issued error messages but exited with exit
+ status 0, which has been corrected.
+ (merge c9e04d905e tg/fetch-prune-exit-code-fix later to maint).
+
+ * Problems identified by Coverity in the reftable code have been
+ corrected.
+ (merge 01033de49f hn/reftable-coverity-fixes later to maint).
+
+ * A bug that made multi-pack bitmap and the object order out-of-sync,
+ making the .midx data corrupt, has been fixed.
+ (merge f8b60cf99b tb/midx-bitmap-corruption-fix later to maint).
+
+ * The build procedure has been taught to notice older version of zlib
+ and enable our replacement uncompress2() automatically.
+ (merge 07564773c2 ab/auto-detect-zlib-compress2 later to maint).
+
+ * Interaction between fetch.negotiationAlgorithm and
+ feature.experimental configuration variables has been corrected.
+ (merge 714edc620c en/fetch-negotiation-default-fix later to maint).
+
+ * "git diff --diff-filter=aR" is now parsed correctly.
+ (merge 75408ca949 js/diff-filter-negation-fix later to maint).
+
+ * When "git subtree" wants to create a merge, it used "git merge" and
+ let it be affected by end-user's "merge.ff" configuration, which
+ has been corrected.
+ (merge 9158a3564a tk/subtree-merge-not-ff-only later to maint).
+
+ * Unlike "git apply", "git patch-id" did not handle patches with
+ hunks that has only 1 line in either preimage or postimage, which
+ has been corrected.
+ (merge 757e75c81e jz/patch-id-hunk-header-parsing-fix later to maint).
+
+ * "receive-pack" checks if it will do any ref updates (various
+ conditions could reject a push) before received objects are taken
+ out of the temporary directory used for quarantine purposes, so
+ that a push that is known-to-fail will not leave crufts that a
+ future "gc" needs to clean up.
+ (merge 5407764069 cb/clear-quarantine-early-on-all-ref-update-errors later to maint).
+
+ * Because a deletion of ref would need to remove it from both the
+ loose ref store and the packed ref store, a delete-ref operation
+ that logically removes one ref may end up invoking ref-transaction
+ hook twice, which has been corrected.
+ (merge 2ed1b64ebd ps/avoid-unnecessary-hook-invocation-with-packed-refs later to maint).
+
+ * When there is no object to write .bitmap file for, "git
+ multi-pack-index" triggered an error, instead of just skipping,
+ which has been corrected.
+ (merge eb57277ba3 tb/midx-no-bitmap-for-no-objects later to maint).
+
+ * "git cmd -h" outside a repository should error out cleanly for many
+ commands, but instead it hit a BUG(), which has been corrected.
+ (merge 87ad07d735 js/short-help-outside-repo-fix later to maint).
+
+ * "working tree" and "per-worktree ref" were in glossary, but
+ "worktree" itself wasn't, which has been corrected.

=== Describe your changes well.
+The log message that explains your changes is just as important as the

+reasons:

+ log message to summarize the thought behind it).
+
+. Your code may be doing things that were only necessary for your
+ immediate needs (e.g. "do X to directories" without implementing or
+ even designing what is to be done on files). Writing down why you
+ excluded what the code does not do will help guide future developers.
+ Writing down "we do X to directories, because directories have
+ characteristic Y" would help them infer "oh, files also have the same
+ characteristic Y, so perhaps doing X to them would also make sense?".
+ Saying "we don't do the same X to files, because ..." will help them
+ decide if the reasoning is sound (in which case they do not waste
+ time extending your code to cover files), or reason differently (in
+ which case, they can explain why they extend your code to cover
+ files, too).
+

- * function and data pointer in a `struct config_include_data`, and pass

- * return git_config_from_file(git_config_include, file, &inc);
