In Git 2.0, the default will change to the "simple" +semantics, which pushes: + + - only the current branch to the branch with the same name, and only + when the current branch is set to integrate with that remote + branch, if you are pushing to the same remote as you fetch from; or + + - only the current branch to the branch with the same name, if you + are pushing to a remote that is not where you usually fetch from. + +Use the user preference configuration variable "push.default" to +change this. If you are an old-timer who is used to the "matching" +semantics, you can set the variable to "matching" to keep the +traditional behaviour. If you want to live in the future early, you +can set it to "simple" today without waiting for Git 2.0. + +When "git add -u" (and "git add -A") is run inside a subdirectory and +does not specify which paths to add on the command line, it +will operate on the entire tree in Git 2.0 for consistency +with "git commit -a" and other commands. There will be no +mechanism to make plain "git add -u" behave like "git add -u .". +Current users of "git add -u" (without a pathspec) should start +training their fingers to explicitly say "git add -u ." +before Git 2.0 comes. A warning is issued when these commands are +run without a pathspec and when you have local changes outside the +current directory, because the behaviour in Git 2.0 will be different +from today's version in such a situation. + +In Git 2.0, "git add " will behave as "git add -A ", so +that "git add dir/" will notice paths you removed from the directory +and record the removal. Versions before Git 2.0, including this +release, will keep ignoring removals, but the users who rely on this +behaviour are encouraged to start using "git add --ignore-removal " +now before 2.0 is released. + +The default prefix for "git svn" will change in Git 2.0. For a long +time, "git svn" created its remote-tracking branches directly under +refs/remotes, but it will place them under refs/remotes/origin/ unless +it is told otherwise with its --prefix option. + + +Updates since v1.8.5 +-------------------- + +Foreign interfaces, subsystems and ports. + + * The HTTP transport, when talking GSS-Negotiate, uses "100 + Continue" response to avoid having to rewind and resend a large + payload, which may not be always doable. + + * Various bugfixes to remote-bzr and remote-hg (in contrib/). + + * The build procedure is aware of MirBSD now. + + +UI, Workflows & Features + + * Fetching from a shallowly-cloned repository used to be forbidden, + primarily because the codepaths involved were not carefully vetted + and we did not bother supporting such usage. This release attempts + to allow object transfer out of a shallowly-cloned repository in a + more controlled way (i.e. the receiver become a shallow repository + with a truncated history). + + * Just like we give a reasonable default for "less" via the LESS + environment variable, we now specify a reasonable default for "lv" + via the "LV" environment variable when spawning the pager. + + * Two-level configuration variable names in "branch.*" and "remote.*" + hierarchies, whose variables are predominantly three-level, were + not completed by hitting a in bash and zsh completions. + + * Fetching 'frotz' branch with "git fetch", while 'frotz/nitfol' + remote-tracking branch from an earlier fetch was still there, would + error out, primarily because the command was not told that it is + allowed to lose any information on our side. "git fetch --prune" + now can be used to remove 'frotz/nitfol' to make room to fetch and + store 'frotz' remote-tracking branch. + + * "diff.orderfile=" configuration variable can be used to + pretend as if the "-O" option were given from the command + line of "git diff", etc. + + * The negative pathspec syntax allows "git log -- . ':!dir'" to tell + us "I am interested in everything but 'dir' directory". + + * "git difftool" shows how many different paths there are in total, + and how many of them have been shown so far, to indicate progress. + + * "git push origin master" used to push our 'master' branch to update + the 'master' branch at the 'origin' repository. This has been + enhanced to use the same ref mapping "git push origin" would use to + determine what ref at the 'origin' to be updated with our 'master'. + For example, with this configuration + + [remote "origin"] + push = refs/heads/*:refs/review/* + + that would cause "git push origin" to push out our local branches + to corresponding refs under refs/review/ hierarchy at 'origin', + "git push origin master" would update 'refs/review/master' over + there. Alternatively, if push.default is set to 'upstream' and our + 'master' is set to integrate with 'topic' from the 'origin' branch, + running "git push origin" while on our 'master' would update their + 'topic' branch, and running "git push origin master" while on any + of our branches does the same. + + * "gitweb" learned to treat ref hierarchies other than refs/heads as + if they are additional branch namespaces (e.g. refs/changes/ in + Gerrit). + + * "git for-each-ref --format=..." learned a few formatting directives; + e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)". + + * The command string given to "git submodule foreach" is passed + directly to the shell, without being eval'ed. This is a backward + incompatible change that may break existing users. + + * "git log" and friends learned the "--exclude=" option, to + allow people to say "list history of all branches except those that + match this pattern" with "git log --exclude='*/*' --branches". + + * "git rev-parse --parseopt" learned a new "--stuck-long" option to + help scripts parse options with an optional parameter. + + * The "--tags" option to "git fetch" no longer tells the command to + fetch _only_ the tags. It instead fetches tags _in addition to_ + what are fetched by the same command line without the option. + + +Performance, Internal Implementation, etc. + + * When parsing a 40-hex string into the object name, the string is + checked to see if it can be interpreted as a ref so that a warning + can be given for ambiguity. The code kicked in even when the + core.warnambiguousrefs is set to false to squelch this warning, in + which case the cycles spent to look at the ref namespace were an + expensive no-op, as the result was discarded without being used. + + * The naming convention of the packfiles has been updated; it used to + be based on the enumeration of names of the objects that are + contained in the pack, but now it also depends on how the packed + result is represented---packing the same set of objects using + different settings (or delta order) would produce a pack with + different name. + + * "git diff --no-index" mode used to unnecessarily attempt to read + the index when there is one. + + * The deprecated parse-options macro OPT_BOOLEAN has been removed; + use OPT_BOOL or OPT_COUNTUP in new code. + + * A few duplicate implementations of prefix/suffix string comparison + functions have been unified to starts_with() and ends_with(). + + * The new PERLLIB_EXTRA makefile variable can be used to specify + additional directories Perl modules (e.g. the ones necessary to run + git-svn) are installed on the platform when building. + + * "git merge-base" learned the "--fork-point" mode, that implements + the same logic used in "git pull --rebase" to find a suitable fork + point out of the reflog entries for the remote-tracking branch the + work has been based on. "git rebase" has the same logic that can be + triggered with the "--fork-point" option. + + * A third-party "receive-pack" (the responder to "git push") can + advertise the "no-thin" capability to tell "git push" not to use + the thin-pack optimization.
