Git 2.9 正式发布了，累计70位该版本贡献者，此次发布新增了许多新特性，以及修复大量Bugs。以下是部分改进记录： * Comes with git-multimail 1.3.1 (in contrib/).
* The end-user facing commands like "git diff" and "git log"
now enable the rename detection by default.
* The credential.helper configuration variable is cumulative and
there is no good way to override it from the command line. As
a special case, giving an empty string as its value now serves
as the signal to clear the values specified in various files.
* A new "interactive.diffFilter" configuration can be used to
customize the diff shown in "git add -i" sessions.
* "git p4" now allows P4 author names to be mapped to Git author
names.
* "git rebase -x" can be used without passing "-i" option.
* "git -c credential.<var>=<value> submodule" can now be used to
propagate configuration variables related to credential helper
down to the submodules. 查看完整改进记录，可以点击这里。 下载地址：https://git-scm.com/download |
