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. + + * We learned to talk to watchman to speed up "git status" and other + operations that need to see which paths have been modified. + + * The "diff" family of commands learned to ignore differences in + carriage return at the end of line. + + * Places that know about "sendemail.to", like documentation and shell + completion (in contrib/) have been taught about "sendemail.tocmd", + too. + + * "git add --renormalize ." is a new and safer way to record the fact + that you are correcting the end-of-line convention and other + "convert_to_git()" glitches in the in-repository data. + + * "git branch" and "git checkout -b" are now forbidden from creating + a branch whose name is "HEAD". + + * "git branch --list" learned to show its output through the pager by + default when the output is going to a terminal, which is controlled + by the pager.branch configuration variable. This is similar to a + recent change to "git tag --list". + + * "git grep -W", "git diff -W" and their friends learned a heuristic + to extend a pre-context beyond the line that matches the "function + pattern" (aka "diff.*.xfuncname") to include a comment block, if + exists, that immediately precedes it. + + * "git config --expiry-date gc.reflogexpire" can read "2.weeks" from + the configuration and report it as a timestamp, just like "--int" + would read "1k" and report 1024, to help consumption by scripts. + + * The shell completion (in contrib/) learned that "git pull" can take + the "--autostash" option. + + * The tagnames "git log --decorate" uses to annotate the commits can + now be limited to subset of available refs with the two additional + options, --decorate-refs[-exclude]=<pattern>. + + * "git grep" compiled with libpcre2 sometimes triggered a segfault, + which is being fixed. + + * "git send-email" tries to see if the sendmail program is available + in /usr/lib and /usr/sbin; extend the list of locations to be + checked to also include directories on $PATH. + + +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. + + * A single-word "unsigned flags" in the diff options is being split + into a structure with many bitfields. + + * 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. + + * Drop (perhaps overly cautious) sanity check before using the index + read from the filesystem at runtime. + + * The build procedure has been taught to avoid some unnecessary + instability in the build products. + + * A new mechanism to upgrade the wire protocol in place is proposed + and demonstrated that it works with the older versions of Git + without harming them. + + * An infrastructure to define what hash function is used in Git is + introduced, and an effort to plumb that throughout various + codepaths has been started. + + * The code to iterate over loose object files got optimized. + + * An internal function that was left for backward compatibility has + been removed, as there is no remaining callers. + +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, which + 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 corrected. + + * "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" instruction 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. + + * 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. + + * Some error messages did not quote filenames shown in it, which have + been fixed. + + * "git rebase -i" recently started misbehaving when a submodule that + is configured with 'submodule.<name>.ignore' is dirty; this has + been corrected. + + * Building with NO_LIBPCRE1_JIT did not disable it, which has been fixed. + + * We used to add an empty alternate object database to the system + that does not help anything; it has been corrected. + + * Doc update around use of "format-patch --subject-prefix" etc. + + * A fix for an ancient bug in "git apply --ignore-space-change" codepath. + + * Clarify and enhance documentation for "merge-base --fork-point", as + it was clear what it computed but not why/what for. + + * A few scripts (both in production and tests) incorrectly redirected + their error output.
