* Added support for git --shared (enabled by default for group) using ``--gitshare`` (11)
* Added option to choose between different git modes using ``--gitmode`` (11)
* monolithic (ALL users share a single repository, NOT recommended because of scalability)
* user (each user/namespace is its own git repository; this is the default)
* nested (each subdirectory is its own git repository, maximum scalability)
* Implemented sane stop behaviour (12)
