WP Git Updater

Display Git Status is a pretty simple plugin, all it needs is access to the <code>shell_exec</code> function and to be pointed at a git repository.
The plugin will not perform any state altering operations, it accesses the repository using read only methods to fetch information like branch name, last commit and status.
When the git repository is located (defaulting to <code>wp-content</code>, or overwritten via a setting) the plugin will add a new admin bar item with the git icon and the current branch name.
When your site has untracked changes the menu items background will turn red.
This is ideal as it gives you a small marker directly in the admin area that some changes have been made which you probably need to look into.
Additionally when accessing the plugins admin page you can see the result of the <code>git status</code> command, and the last commit applied to your site.

This is a plugin for managing website releases under production or development 
environments. Once the WordPress installation is in a Git tree, WP Deploy will 
detect its branches and put a switch menu in the admin bar.
Like this, you can just push your website to your remote and use the menu to 
deploy the changes without using Git hooks or prompting into another shell.
Another useful purpose is for the development process, where different 
implementations can be viewed and switched by customers, or a production branch 
can be testes in a staging environment.

WP Git Deploy
