We started this by first + deprecating and warning a pathspec that has such an element in + 2.11 (Nov 2016). + + * A hook script that is set unexecutable is simply ignored. Git + notifies when such a file is ignored, unless the message is + squelched via advice.ignoredHook configuration. + + * "git pull" has been taught to accept "--[no-]signoff" option and + pass it down to "git merge". + + * The "--push-option=<string>" option to "git push" now defaults to a + list of strings configured via push.pushOption variable. + + * "gitweb" checks if a directory is searchable with Perl's "-x" + operator, which can be enhanced by using "filetest 'access'" + pragma, which now we do. + + * "git stash save" has been deprecated in favour of "git stash push". + + * The set of paths output from "git status --ignored" was tied + closely with its "--untracked=<mode>" option, but now it can be + controlled more flexibly. Most notably, a directory that is + ignored because it is listed to be ignored in the ignore/exclude + mechanism can be handled differently from a directory that ends up + to be ignored only because all files in it are ignored. + + * The remote-helper for talking to MediaWiki has been updated to + truncate an overlong pagename so that ".mw" suffix can still be + added. + + * The remote-helper for talking to MediaWiki has been updated to + work with mediawiki namespaces. + + * The "--format=..." option "git for-each-ref" takes learned to show + the name of the 'remote' repository and the ref at the remote side + that is affected for 'upstream' and 'push' via "%(push:remotename)" + and friends. + + * Doc and message updates to teach users "bisect view" is a synonym + for "bisect visualize". + + * "git bisect run" that did not specify any command to run used to go + ahead and treated all commits to be tested as 'good'. This has + been corrected by making the command error out. + + * The SubmittingPatches document has been converted to produce an + HTML version via AsciiDoc/Asciidoctor. + (merge 049e64aa50 bc/submitting-patches-in-asciidoc later to maint). + + +Performance, Internal Implementation, Development Support etc. + + * An earlier update made it possible to use an on-stack in-core + lockfile structure (as opposed to having to deliberately leak an + on-heap one). Many codepaths have been updated to take advantage + of this new facility. + + * Calling cmd_foo() as if it is a general purpose helper function is + a no-no. Correct two instances of such to set an example. + + * We try to see if somebody runs our test suite with a shell that + does not support "local" like bash/dash does. + + * An early part of piece-by-piece rewrite of "git bisect" in C. + + * GSoC to piece-by-piece rewrite "git submodule" in C. + + * Optimize the code to find shortest unique prefix of object names. + + * Pathspec-limited revision traversal was taught not to keep finding + unneeded differences once it knows two trees are different inside + given pathspec. + + * Conversion from uchar[20] to struct object_id continues. + + * Code cleanup. + (merge 62a24c8923 rs/hex-to-bytes-cleanup later to maint). + + * A single-word "unsigned flags" in the diff options is being split + into a structure with many bitfields. + (merge 0d1e0e7801 bw/diff-opt-impl-to-bitfields later to maint). + + * TravisCI build updates. + + * Parts of a test to drive the long-running content filter interface + has been split into its own module, hopefully to eventually become + reusable. + (merge 0fe8d516bb cc/git-packet-pm later to maint). + + * Drop (perhaps overly cautious) sanity check before using the index + read from the filesystem at runtime. + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.15 +----------------- + + * "auto" as a value for the columnar output configuration ought to + judge "is the output consumed by humans?" with the same criteria as + "auto" for coloured output configuration, i.e. either the standard + output stream is going to tty, or a pager is in use. We forgot the + latter, which has been fixed. + + * The experimental "color moved lines differently in diff output" + feature was buggy around "ignore whitespace changes" edges, whihch + has been corrected. + + * Instead of using custom line comparison and hashing functions to + implement "moved lines" coloring in the diff output, use the pair + of these functions from lower-layer xdiff/ code. + + * Some codepaths did not check for errors when asking what branch the + HEAD points at, which have been fixed. + + * "git commit", after making a commit, did not check for errors when + asking on what branch it made the commit, which has been correted. + + * "git status --ignored -u" did not stop at a working tree of a + separate project that is embedded in an ignored directory and + listed files in that other project, instead of just showing the + directory itself as ignored. + + * A broken access to object databases in recent update to "git grep + --recurse-submodules" has been fixed. + + * A recent regression in "git rebase -i" that broke execution of git + commands from subdirectories via "exec" insn has been fixed. + + * A (possibly flakey) test fix. + + * "git check-ref-format --branch @{-1}" bit a "BUG()" when run + outside a repository for obvious reasons; clarify the documentation + and make sure we do not even try to expand the at-mark magic in + such a case, but still call the validation logic for branch names. + + * "git fetch --recurse-submodules" now knows that submodules can be + moved around in the superproject in addition to getting updated, + and finds the ones that need to be fetched accordingly. + + * Command line completion (in contrib/) update. + + * Description of blame.{showroot,blankboundary,showemail,date} + configuration variables have been added to "git config --help". + + * After an error from lstat(), diff_populate_filespec() function + sometimes still went ahead and used invalid data in struct stat, + which has been fixed. + + * UNC paths are also relevant in Cygwin builds and they are now + tested just like Mingw builds. + + * Correct start-up sequence so that a repository could be placed + immediately under the root directory again (which was broken at + around Git 2.13). + + * The credential helper for libsecret (in contrib/) has been improved + to allow possibly prompting the end user to unlock secrets that are + currently locked (otherwise the secrets may not be loaded). + + * MinGW updates. + + * Error checking in "git imap-send" for empty response has been + improved. + (merge 618ec81abb rs/imap-send-next-arg-fix later to maint). + + * Recent update to the refs infrastructure implementation started + rewriting packed-refs file more often than before; this has been + optimized again for most trivial cases. + (merge 7c6bd25c7d mh/avoid-rewriting-packed-refs later to maint). + + * Some error messages did not quote filenames shown in it, which have + been fixed. + (merge 0a288d1ee9 sr/wrapper-quote-filenames later to maint). + + * "git rebase -i" recently started misbehaving when a submodule that + is configured with 'submodule.<name>.ignore' is dirty; this has + been corrected. + (merge c6d8ccf3a2 bw/rebase-i-ignored-submodule-fix later to maint). + + * Building with NO_LIBPCRE1_JIT did not disable it, which has been fixed. + (merge 2fff1e196d ab/pcre-v2 later to maint). + + * We used to add an empty alternate object database to the system + that does not help anything; it has been corrected. + (merge f28e36686a jk/info-alternates-fix later to maint). + + * Other minor doc, test and build updates and code cleanups. + (merge 804862209b ao/merge-verbosity-getenv-just-once later to maint). + (merge 9360ec0002 rs/sequencer-rewrite-file-cleanup later to maint). + (merge f4e45cb3eb ma/bisect-leakfix later to maint). + (merge 4da72644b7 ma/reduce-heads-leakfix later to maint). + (merge 3dc5433fd5 ad/rebase-i-serie-typofix later to maint). + (merge 5313bee032 tz/fsf-address-update later to maint). + (merge 5555a2aa4b cb/t4201-robustify later to maint). |
