Hi,

I am learning how git works, and is using the excellent book on the official site. I believe I have located a mistake in one of the images. It is about Figure 3.17 on this page : http://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging

As far as I understand it, the right most snapshot called C5 should have been named C6. The texts describes a new snapshot being made from the merge of the 2 branches. Having 2 snapshots both named C5 does not seem like it can be possible.

Indeed you are correct. Looks like this was fixed a while ago https://github.com/progit/progit2/commit/3491527b33251fcacd8d2964bf7fb5e0f1cfe455 but hasn't made it into the "live" website.

Your hunch is correct, and it should be C6, that's why it was changed:

https://github.com/progit/progit2/blob/master/book/03-git-branching/images/basic-merging-2.png

I do not know why it is still displayed incorrectly on https://git-scm.com/, but your best bet would be to report this as a bug: https://github.com/git/git-scm.com/issues

But make sure first that there is not another ticket opened for the same bug!

Ciao, Johannes
