By setting it to 'auto', you can turn it on only for a + series with two or more patches. + + * The bash completion support (in contrib/) learned that cherry-pick + takes a few more options than it already knew about. + + * "git help" learned "-g" option to show the list of guides just like + list of commands are given with "-a". + + * A triangular "pull from one place, push to another place" workflow + is supported better by new remote.pushdefault (overrides the + "origin" thing) and branch.*.pushremote (overrides the + branch.*.remote) configuration variables. + + * "git status" learned to report that you are in the middle of a + revert session, just like it does for a cherry-pick and a bisect + session. + + * The handling by "git branch --set-upstream-to" against various forms + of erroneous inputs was suboptimal and has been improved. + + * When the interactive access to git-shell is not enabled, it issues + a message meant to help the system administrator to enable it. + An explicit way to help the end users who connect to the service by + issuing custom messages to refuse such an access has been added. + + * In addition to the case where the user edits the log message with + the "e)dit" option of "am -i", replace the "Applying: this patch" + message with the final log message contents after applymsg hook + munges it. + + * "git status" suggests users to look into using --untracked=no option + when it takes too long. + + * "git status" shows a bit more information to "git status" during a + rebase/bisect session. + + * "git fetch" learned to fetch a commit at the tip of an unadvertised + ref by specifying a raw object name from the command line when the + server side supports this feature. + + * Output from "git log --graph" works better with submodule log + output now. + + * "git count-objects -v" learned to report leftover temporary + packfiles and other garbage in the object store. + + * A new read-only credential helper (in contrib/) to interact with + the .netrc/.authinfo files has been added. + + * "git send-email" can be used with the credential helper system. + + * There was no Porcelain way to say "I no longer am interested in + this submodule", once you express your interest in a submodule with + "submodule init". "submodule deinit" is the way to do so. + + * "git pull --rebase" learned to pass "-v/-q" options to underlying + "git rebase". + + * The new "--follow-tags" option tells "git push" to push relevant + annotated tags when pushing branches out. + + * "git merge" and "git pull" can optionally be told to inspect and + reject when merging a commit that does not carry a trusted GPG + signature. + + * "git mergetool" now feeds files to the "p4merge" backend in the + order that matches the p4 convention, where "theirs" is usually + shown on the left side, which is the opposite from other backend + expects. + + * "show/log" now honors gpg.program configuration just like other + parts of the code that use GnuPG. + + * "git log" that shows the difference between the parent and the + child has been optimized somewhat. + + * "git difftool" allows the user to write into the temporary files + being shown; if the user makes changes to the working tree at the + same time, one of the changes has to be lost in such a case, but it + tells the user what happened and refrains from overwriting the copy + in the working tree. + + * There was no good way to ask "I have a random string that came from + outside world.

A new peeling suffix ^{object} + can be used for that purpose, together with "rev-parse --verify". + + +Performance, Internal Implementation, etc. + + * Updates for building under msvc. + + * The stack footprint of some codepaths that access an object from a + pack has been shrunk. + + * The logic to coalesce the same lines removed from the parents in + the output from "diff -c/--cc" has been updated, but with an O(n^2) + complexity, so this might turn out to be undesirable. + + * The code to enforce permission bits on files in $GIT_DIR/ for + shared repositories have been simplified. + + * A few codepaths knew how much data they need to put in the + hashtables they use upfront, but still started from a small table + repeatedly growing and rehashing. + + * The API to walk reflog entries from the latest to older, which was + necessary for operations such as "git checkout -", was cumbersome + to use correctly and also inefficient. + + * Codepaths that inspect log-message-to-be and decide when to add a + new Signed-off-by line in various commands have been consolidated. + + * The pkt-line API, implementation and its callers have been cleaned + up to make them more robust. + + * Cygwin port has a faster-but-lying lstat(2) emulation whose + incorrectness does not matter in practice except for a few + codepaths, and setting permission bits to directories is a codepath + that needs to use a more correct one. + + * "git checkout" had repeated pathspec matches on the same paths, + which have been consolidated. Also a bug in "git checkout dir/" + that is started from an unmerged index has been fixed. + + * A few bugfixes to "git rerere" working on corner case merge + conflicts have been applied. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v1.8.2 +------------------ + +Unless otherwise noted, all the fixes since v1.8.2 in the maintenance +track are contained in this release (see release notes to them for +details). + + * When "upload-pack" fails while generating a pack in response to + "git fetch" (or "git clone"), the receiving side mistakenly said + there was a programming error to trigger the die handler + recursively. + (merge 1ece66b jk/a-thread-only-dies-once later to maint). + + * "rev-list --stdin" and friends kept bogus pointers into input + buffer around as human readble object names.
