In Git 2.0, the default will change to the "simple" +semantics that pushes the current branch to the branch with the same +name, only when the current branch is set to integrate with that +remote branch. There is a 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 it 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", that does not specify what paths +to add on the command line is run from inside a subdirectory, these +commands will operate on the entire tree in Git 2.0 for consistency +with "git commit -a" and other commands. Because there will be no +mechanism to make "git add -u" behave as if "git add -u .", it is +important for those who are used to "git add -u" (without pathspec) +updating the index only for paths in the current subdirectory to start +training their fingers to explicitly say "git add -u ." when they mean +it before Git 2.0 comes. + + +Updates since v1.8.2 +-------------------- + +UI, Workflows & Features + + * When the interactive access to git-shell is not enabled, it issues + a message meant to help the system admininstrator 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. + + * "git status" suggests users to look into using--untracked=no option + when it takes too long. + + * "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. + + * "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".
