Existing users who prefer not to see line-wrapped + output may want to set + + $ git config core.pager "less -S" + + to restore the traditional behaviour.

"S" (chop + long lines instead of wrapping) has been removed from this default + set of options, because it is more or less a personal taste thing, + as opposed to the others that have good justifications (i.e. "R" is + very much justified because many kinds of output we produce are + colored and "FX" is justified because output we produce is often + shorter than a page). + + * The logic and data used to compute the display width needed for + UTF-8 strings have been updated to match Unicode 7.0 better. + + * HTTP-based transports learned to better propagate the error messages from + the webserver to the client coming over the HTTP transport. + + * The completion script for bash (in contrib/) has been updated to + better handle aliases that define a complex sequence of commands. + + * The "core.preloadindex" configuration variable is enabled by default, + allowing modern platforms to take advantage of their + multiple cores. + + * "git clone" applies the "if cloning from a local disk, physically + copy the repository using hardlinks, unless otherwise told not to with + --no-local" optimization when the url.*.insteadOf mechanism rewrites a + remote-repository "git clone $URL" into a + clone from a local disk. + + * "git commit --date=<date>" option learned more + timestamp formats, including "--date=now". + + * The `core.commentChar` configuration variable is used to specify a + custom comment character (other than the default "#") for + the commit message editor. This can be set to `auto` to attempt to + choose a different character that does not conflict with any that + already starts a line in the message being edited, for cases like + "git commit --amend". + + * "git format-patch" learned --signature-file=<file> to add the contents + of a file as a signature to the mail message it produces. + + * "git grep" learned the grep.fullname configuration variable to force + "--full-name" to be the default. This may cause regressions for + scripted users who do not expect this new behaviour. + + * "git imap-send" learned to ask the credential helper for auth + material. + + * "git log" and friends now understand the value "auto" for the + "log.decorate" configuration variable to enable the "--decorate" + option automatically when the output is sent to tty. + + * "git merge" without an argument, even when there is an upstream + defined for the current branch, refused to run until + merge.defaultToUpstream is set to true. Flip the default of that + configuration variable to true. + + * "git mergetool" learned to drive the vimdiff3 backend. + + * mergetool.prompt used to default to 'true', always asking "do you + really want to run the tool on this path?". The default has been + changed to 'false'. However, the prompt will still appear if + mergetool used its autodetection system to guess which tool to use. + Users who explicitly specify or configure a tool will no longer see + the prompt by default. + + Strictly speaking, this is a backward incompatible change and + users need to explicitly set the variable to 'true' if they want + to be prompted to confirm running the tool on each path. + + * "git replace" learned the "--edit" subcommand to create a + replacement by editing an existing object. + + * "git replace" learned a "--graft" option to rewrite the parents of a + commit. + + * "git send-email" learned "--to-cover" and "--cc-cover" options, to + tell it to copy To: and Cc: headers found in the first input file + when emitting later input files. + + * "git svn" learned to cope with malformed timestamps with only one + digit in the hour part, e.g. 2014-01-07T5:01:02.048176Z, emitted + by some broken subversion server implementations. + + * "git tag" when editing the tag message shows the name of the tag + being edited as a comment in the editor. + + * "git tag" learned to pay attention to "tag.sort" configuration, to + be used as the default sort order when no --sort=<value> option + is given. + + * A new "git verify-commit" command, to check GPG signatures in signed + commits, in a way similar to "git verify-tag" is used to check + signed tags, was added. + + +Performance, Internal Implementation, etc. + + * Build procedure for 'subtree' (in contrib/) has been cleaned up. + + * Support for the profile-feedback build, which has + bit-rotted for quite a while, has been updated. + + * An experimental format to use two files (the base file and + incremental changes relative to it) to represent the index has been + introduced; this may reduce I/O cost of rewriting a large index + when only small part of the working tree changes. + + * Effort to shrink the size of patches Windows folks maintain on top + by upstreaming them continues. More tests that are not applicable + to the Windows environment are identified and either skipped or + made more portable. + + * Eradication of "test $condition -a $condition" from our scripts + continues. + + * The `core.deltabasecachelimit` used to default to 16 MiB , but this + proved to be too small, and has been bumped to 96 MiB. + + * "git blame" has been optimized greatly by reorganising the data + structure that is used to keep track of the work to be done. + + * "git diff" that compares 3-or-more trees (e.g. parents and the + result of a merge) has been optimized. + + * The API to update/delete references are being converted to handle + updates to multiple references in a transactional way. As an + example, "update-ref --stdin [-z]" has been updated to use this + API. + + * skip_prefix() and strip_suffix() API functions are used a lot more + widely throughout the codebase now. + + * Parts of the test scripts can be skipped by using a range notation, + e.g. "sh t1234-test.sh --run='1-4 6 8-'" to omit test piece 5 and 7 + and run everything else. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.0 +---------------- + +Unless otherwise noted, all the fixes since v2.0 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * We used to unconditionally disable the pager in the pager process + we spawn to feed out output, but that prevented people who want to + run "less" within "less" from doing so. + (merge c0459ca je/pager-do-not-recurse later to maint). + + * Tools that read diagnostic output in our standard error stream do + not want to see terminal control sequence (e.g. erase-to-eol). + Detect them by checking if the standard error stream is connected + to a tty. + (merge 38de156 mn/sideband-no-ansi later to maint). + + * Mishandling of patterns in .gitignore that have trailing SPs quoted + with backslashes (e.g. ones that end with "\ ") has been + corrected. + (merge 97c1364be6b pb/trim-trailing-spaces later to maint). + + * Reworded the error message given upon a failure to open an existing + loose object file due to e.g. permission issues; it was reported as + the object being corrupt, but that is not quite true. + (merge d6c8a05 jk/report-fail-to-read-objects-better later to maint). + + * "git log -2master" is a common typo that shows two commits starting + from whichever random branch that is not 'master' that happens to + be checked out currently. + (merge e3fa568 jc/revision-dash-count-parsing later to maint). + + * Code to avoid adding the same alternate object store twice was + subtly broken for a long time, but nobody seems to have noticed. + (merge 80b4785 rs/fix-alt-odb-path-comparison later to maint). + (merge 539e750 ek/alt-odb-entry-fix later to maint). + + * The "%<(10,trunc)%s" pretty format specifier in the log family of + commands is used to truncate the string to a given length (e.g. 10 + in the example) with padding to column-align the output, but did + not take into account that number of bytes and number of display + columns are different. + (merge 7d50987 as/pretty-truncate later to maint). + + * "%G" (nothing after G) is an invalid pretty format specifier, but + the parser did not notice it as garbage. + (merge 958b2eb jk/pretty-G-format-fixes later to maint). + + * A handful of code paths had to read the commit object more than + once when showing header fields that are usually not parsed.

A few commands + have been converted to use this subsystem. + + * Various code paths have been cleaned up and simplified by using + the "strbuf", "starts_with()", and "skip_prefix()" APIs more. + + * A few codepaths that died when large blobs that would not fit in + core are involved in their operation have been taught to punt + instead, by e.g. marking a too-large blob as not to be diffed. + + * A few more code paths in "commit" and "checkout" have been taught + to repopulate the cache-tree in the index, to help speed up later + "write-tree" (used in "commit") and "diff-index --cached" (used in + "status"). + + * A common programming mistake to assign the same short option name + to two separate options is detected by the parse_options() API to help + developers. + + * The code path to write out the packed-refs file has been optimized, + which especially matters in a repository with a large number of + refs. + + * The check to see if a ref $F can be created by making sure no + existing ref has $F/ as its prefix has been optimized, which + especially matters in a repository with a large number of existing + refs. + + * "git fsck" was taught to check the contents of tag objects a bit more. + + * "git hash-object" was taught a "--literally" option to help + debugging. + + * When running a required clean filter, we do not have to mmap the + original before feeding the filter. Instead, stream the file + contents directly to the filter and process its output. + + * The scripts in the test suite can be run with the "-x" option to show + a shell-trace of each command they run. + + * The "run-command" API learned to manage the argv and environment + arrays for child process, alleviating the need for the callers to + allocate and deallocate them. + + * Some people use AsciiDoctor, instead of AsciiDoc, to format our + documentation set; the documentation has been adjusted to be usable + by both, as AsciiDoctor is pickier than AsciiDoc about its input + mark-up. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.1 +---------------- + +Unless otherwise noted, all the fixes since v2.1 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * "git log --pretty/format=" with an empty format string did not + mean the more obvious "No output whatsoever" but "Use default + format", which was counterintuitive. + + * "git -c section.var command" and "git -c section.var= command" + should pass the configuration value differently (the former should be a + boolean true, the latter should be an empty string). + + * Applying a patch not generated by Git in a subdirectory used to + check for whitespace breakage using the attributes of incorrect + paths.
