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.
