GIT 1.0.0 is found at the usual places:
The name “1.0.0” ought to mean a significant milestone, but actually it is not. Pre 1.0 version has been in production use by the kernel folks for quite some time, and the changes since 1.0rc are pretty small and primarily consist of documenation updates, clone/fetch enhancements and miscellaneous bugfixes.
Thank you all who gave patches, comments and time.
Happy hacking, and a little early ho-ho-ho.
