-Git 2.6 Release Notes
-=====================
-
-Updates since v2.5
-------------------
-
-UI, Workflows & Features
-
- * An asterisk as a substring (as opposed to the entirety) of a path
-   component for both side of a refspec, e.g.
-   "refs/heads/o*:refs/remotes/heads/i*", is now allowed.
-
- * New userdiff pattern definition for fountain screenwriting markup
-   format has been added.
-
- * "git log" and friends learned a new "--date=format:..." option to
-   format timestamps using system's strftime(3).
-
- * "git fast-import" learned to respond to the get-mark command via
-   its cat-blob-fd interface.
-
- * "git rebase -i" learned "drop commit-object-name subject" command
-   as another way to skip replaying of a commit.
-
- * A new configuration variable can enable "--follow" automatically
-   when "git log" is run with one pathspec argument.
-
- * "git status" learned to show a more detailed information regarding
-   the "rebase -i" session in progress.
-
- * "git cat-file" learned "--batch-all-objects" option to enumerate all
-   available objects in the repository more quickly than "rev-list
-   --all --objects" (the output includes unreachable objects, though).
-
- * "git fsck" learned to ignore errors on a set of known-to-be-bad
-   objects, and also allows the warning levels of various kinds of
-   non-critical breakages to be tweaked.
-
- * "git rebase -i"'s list of todo is made configurable.
-
- * "git send-email" now performs alias-expansion on names that are
-   given via --cccmd, etc.
-
- * An environment variable GIT_REPLACE_REF_BASE tells Git to look into
-   refs hierarchy other than refs/replace/ for the object replacement
-   data.
-
- * Allow untracked cache (experimental) to be used when sparse
-   checkout (experimental) is also in use.
-
- * "git pull --rebase" has been taught to pay attention to
-   rebase.autostash configuration.
-
- * The command-line completion script (in contrib/) has been updated.
-
- * A negative !ref entry in multi-value transfer.hideRefs
-   configuration can be used to say "don't hide this one".
-
- * After "git am" without "-3" stops, running "git am -3" pays attention
-   to "-3" only for the patch that caused the original invocation
-   to stop.
-
- * When linked worktree is used, simultaneous "notes merge" instances
-   for the same ref in refs/notes/* are prevented from stomping on
-   each other.
-
- * "git send-email" learned a new option --smtp-auth to limit the SMTP
-   AUTH mechanisms to be used to a subset of what the system library
-   supports.
-
- * A new configuration variable http.sslVersion can be used to specify
-   what specific version of SSL/TLS to use to make a connection.
-
- * "git notes merge" can be told with "--strategy=<how>" option how to
-   automatically handle conflicts; this can now be configured by
-   setting notes.mergeStrategy configuration variable.
-
- * "git log --cc" did not show any patch, even though most of the time
-   the user meant "git log --cc -p -m" to see patch output for commits
-   with a single parent, and combined diff for merge commits.  The
-   command is taught to DWIM "--cc" (without "--raw" and other forms
-   of output specification) to "--cc -p -m".
-
- * "git config --list" output was hard to parse when values consist of
-   multiple lines.  "--name-only" option is added to help this.
-
- * A handful of usability & cosmetic fixes to gitk and l10n updates.
-
- * A completely empty e-mail address <> is now allowed in the authors
-   file used by git-svn, to match the way it accepts the output from
-   authors-prog.
-
-
-Performance, Internal Implementation, Development Support etc.
-
- * In preparation for allowing different "backends" to store the refs
-   in a way different from the traditional "one ref per file in
-   $GIT_DIR or in a $GIT_DIR/packed-refs file" filesystem storage,
-   direct filesystem access to ref-like things like CHERRY_PICK_HEAD
-   from scripts and programs has been reduced.
-
- * Computation of untracked status indicator by bash prompt
-   script (in contrib/) has been optimized.
-
- * Memory use reduction when commit-slab facility is used to annotate
-   sparsely (which is not recommended in the first place).
-
- * Clean up refs API and make "git clone" less intimate with the
-   implementation detail.
-
- * "git pull" was reimplemented in C.
-
- * The packet tracing machinery allows to capture an incoming pack
-   data to a file for debugging.
-
- * Move machinery to parse human-readable scaled numbers like 1k, 4M,
-   and 2G as an option parameter's value from pack-objects to
-   parse-options API, to make it available to other codepaths.
-
- * "git verify-tag" and "git verify-commit" have been taught to share
-   more code, and then learned to optionally show the verification
-   message from the underlying GPG implementation.
-
- * Various enhancements around "git am" reading patches generated by
-   foreign SCM have been made.
-
- * Ref listing by "git branch -l" and "git tag -l" commands has
-   started to be rebuilt, based on the for-each-ref machinery.
-
- * The code to perform multi-tree merges has been taught to repopulate
-   the cache-tree upon a successful merge into the index, so that
-   subsequent "diff-index --cached" (hence "status") and "write-tree"
-   (hence "commit") will go faster.
-
-   The same logic in "git checkout" may now be removed, but that is a
-   separate issue.
-
- * Tests that assume how reflogs are represented on the filesystem too
-   much have been corrected.
-
- * "git am" has been rewritten in "C".
-
- * git_path() and mkpath() are handy helper functions but it is easy
-   to misuse, as the callers need to be careful to keep the number of
-   active results below 4.  Their uses have been reduced.
-
- * The "lockfile" API has been rebuilt on top of a new "tempfile" API.
-
- * To prepare for allowing a different "ref" backend to be plugged in
-   to the system, update_ref()/delete_ref() have been taught about
-   ref-like things like MERGE_HEAD that are per-worktree (they will
-   always be written to the filesystem inside $GIT_DIR).
-
- * The gitmodules API that is accessed from the C code learned to
-   cache stuff lazily.
-
-
-Also contains various documentation updates and code clean-ups.
-
-
-Fixes since v2.5
-----------------
-
-Unless otherwise noted, all the fixes since v2.5 in the maintenance
-track are contained in this release (see the maintenance releases'
-notes for details).
-
- * "git subtree" (in contrib/) depended on "git log" output to be
-   stable, which was a no-no.  Apply a workaround to force a
-   particular date format.
-   (merge e7aac44 da/subtree-date-confusion later to maint).
-
- * An attempt to delete a ref by pushing into a repository whose HEAD
-   symbolic reference points at an unborn branch that cannot be
-   created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
-   points at refs/heads/a) failed.
-   (merge b112b14 jx/do-not-crash-receive-pack-wo-head later to maint).
-
- * The low-level "git send-pack" did not honor 'user.signingkey'
-   configuration variable when sending a signed-push.
-   (merge d830d39 db/send-pack-user-signingkey later to maint).
-
- * "sparse checkout" misbehaved for a path that is excluded from the
-   checkout when switching between branches that differ at the path.
-   (merge 7d78241 as/sparse-checkout-removal later to maint).
-
- * An experimental "untracked cache" feature used uname(2) in a
-   slightly unportable way.
-   (merge 100e433 cb/uname-in-untracked later to maint).
-
- * A "rebase" replays changes of the local branch on top of something
-   else, as such they are placed in stage #3 and referred to as
-   "theirs", while the changes in the new base, typically a foreign
-   work, are placed in stage #2 and referred to as "ours".  Clarify
-   the "checkout --ours/--theirs".
-   (merge f303016 se/doc-checkout-ours-theirs later to maint).
-
- * The "rev-parse --parseopt" mode parsed the option specification
-   and the argument hint in a strange way to allow '=' and other
-   special characters in the option name while forbidding them from
-   the argument hint.  This made it impossible to define an option
-   like "--pair <key>=<value>" with "pair=key=value" specification,
-   which instead would have defined a "--pair=key <value>" option.
-   (merge 2d893df ib/scripted-parse-opt-better-hint-string later to maint).
-
- * Often a fast-import stream builds a new commit on top of the
-   previous commit it built, and it often unconditionally emits a
-   "from" command to specify the first parent, which can be omitted in
-   such a case.  This caused fast-import to forget the tree of the
-   previous commit and then re-read it from scratch, which was
-   inefficient.  Optimize for this common case.
-   (merge 0df3245 mh/fast-import-optimize-current-from later to maint).
-
- * Running an aliased command from a subdirectory when the .git thing
-   in the working tree is a gitfile pointing elsewhere did not work.
-   (merge d95138e nd/export-worktree later to maint).
-
- * "Is this subdirectory a separate repository that should not be
-   touched?" check "git clean" was inefficient.  This was replaced
-   with a more optimized check.
-   (merge fbf2fec ee/clean-remove-dirs later to maint).
-
- * The "new-worktree-mode" hack in "checkout" that was added in
-   nd/multiple-work-trees topic has been removed by updating the
-   implementation of new "worktree add".
-   (merge 65f9b75 es/worktree-add-cleanup later to maint).
-
- * Remove remaining cruft from  "git checkout --to", which
-   transitioned to "git worktree add".
-   (merge 114ff88 es/worktree-add later to maint).
-
- * An off-by-one error made "git remote" to mishandle a remote with a
-   single letter nickname.
-   (merge bc598c3 mh/get-remote-group-fix later to maint).
-
- * "git clone $URL", when cloning from a site whose sole purpose is to
-   host a single repository (hence, no path after <scheme>://<site>/),
-   tried to use the site name as the new repository name, but did not
-   remove username or password when <site> part was of the form
-   <user>@<pass>:<host>.  The code is taught to redact these.
-   (merge adef956 ps/guess-repo-name-at-root later to maint).
-
- * Running tests with the "-x" option to make them verbose had some
-   unpleasant interactions with other features of the test suite.
-   (merge 9b5fe78 jk/test-with-x later to maint).
-
- * t1509 test that requires a dedicated VM environment had some
-   bitrot, which has been corrected.
-   (merge faacc5a ps/t1509-chroot-test-fixup later to maint).
-
- * "git pull" in recent releases of Git has a regression in the code
-   that allows custom path to the --upload-pack=<program>.  This has
-   been corrected.
-
-   Note that this is irrelevant for 'master' with "git pull" rewritten
-   in C.
-   (merge 13e0e28 mm/pull-upload-pack later to maint).
-
- * When trying to see that an object does not exist, a state errno
-   leaked from our "first try to open a packfile with O_NOATIME and
-   then if it fails retry without it" logic on a system that refuses
-   O_NOATIME.  This confused us and caused us to die, saying that the
-   packfile is unreadable, when we should have just reported that the
-   object does not exist in that packfile to the caller.
-   (merge dff6f28 cb/open-noatime-clear-errno later to maint).
-
- * The codepath to produce error messages had a hard-coded limit to
-   the size of the message, primarily to avoid memory allocation while
-   calling die().
-   (merge f4c3edc jk/long-error-messages later to maint).
-
- * strbuf_read() used to have one extra iteration (and an unnecessary
-   strbuf_grow() of 8kB), which was eliminated.
-   (merge 3ebbd00 jh/strbuf-read-use-read-in-full later to maint).
-
- * We rewrote one of the build scripts in Perl but this reimplements
-   in Bourne shell.
-   (merge 57cee8a sg/help-group later to maint).
-
- * The experimental untracked-cache feature were buggy when paths with
-   a few levels of subdirectories are involved.
-   (merge 73f9145 dt/untracked-subdir later to maint).
-
- * "interpret-trailers" helper mistook a single-liner log message that
-   has a colon as the end of existing trailer.
-
- * The "interpret-trailers" helper mistook a multi-paragraph title of
-   a commit log message with a colon in it as the end of the trailer
-   block.
-   (merge 5c99995 cc/trailers-corner-case-fix later to maint).
-
- * "git describe" without argument defaulted to describe the HEAD
-   commit, but "git describe --contains" didn't.  Arguably, in a
-   repository used for active development, such defaulting would not
-   be very useful as the tip of branch is typically not tagged, but it
-   is better to be consistent.
-   (merge 2bd0706 sg/describe-contains later to maint).
-
- * The client side codepaths in "git push" have been cleaned up
-   and the user can request to perform an optional "signed push",
-   i.e. sign only when the other end accepts signed push.
-   (merge 68c757f db/push-sign-if-asked later to maint).
-
- * Because the configuration system does not allow "alias.0foo" and
-   "pager.0foo" as the configuration key, the user cannot use '0foo'
-   as a custom command name anyway, but "git 0foo" tried to look these
-   keys up and emitted useless warnings before saying '0foo is not a
-   git command'.  These warning messages have been squelched.
-   (merge 9e9de18 jk/fix-alias-pager-config-key-warnings later to maint).
-
- * "git rev-list" does not take "--notes" option, but did not complain
-   when one is given.
-   (merge 2aea7a5 jk/rev-list-has-no-notes later to maint).
-
- * When re-priming the cache-tree opportunistically while committing
-   the in-core index as-is, we mistakenly invalidated the in-core
-   index too aggressively, causing the experimental split-index code
-   to unnecessarily rewrite the on-disk index file(s).
-   (merge 475a344 dt/commit-preserve-base-index-upon-opportunistic-cache-tree-update later to maint).
-
- * "git archive" did not use zip64 extension when creating an archive
-   with more than 64k entries, which nobody should need, right ;-)?
-   (merge 88329ca rs/archive-zip-many later to maint).
-
- * The code in "multiple-worktree" support that attempted to recover
-   from an inconsistent state updated an incorrect file.
-   (merge 82fde87 nd/fixup-linked-gitdir later to maint).
-
- * On case insensitive systems, "git p4" did not work well with client
-   specs.
-
- * "git init empty && git -C empty log" said "bad default revision 'HEAD'",
-   which was found to be a bit confusing to new users.
-   (merge ce11360 jk/log-missing-default-HEAD later to maint).
-
- * Recent versions of scripted "git am" has a performance regression in
-   "git am --skip" codepath, which no longer exists in the built-in
-   version on the 'master' front.  Fix the regression in the last
-   scripted version that appear in 2.5.x maintenance track and older.
-   (merge b9d6689 js/maint-am-skip-performance-regression later to maint).
-
- * The branch descriptions that are set with "git branch --edit-description"
-   option were used in many places but they weren't clearly documented.
-   (merge 561d2b7 po/doc-branch-desc later to maint).
-
- * Code cleanups and documentation updates.
-   (merge 1c601af es/doc-clean-outdated-tools later to maint).
-   (merge 3581304 kn/tag-doc-fix later to maint).
-   (merge 3a59e59 kb/i18n-doc later to maint).
-   (merge 45abdee sb/remove-unused-var-from-builtin-add later to maint).
