Should I be concerned? The message would have said "ignoring BASE extension", but this means you used git from 'next' to update your index and HEAD and then are now running 'git add' from 'master' or older that does not have the support for BASE extension. For description of what BASE extension does, look at log messages between master..a640e62, especially 0679f9ac. The notice is harmless. Any extension data section that the index file can have, whose name begins with a capital letter (like 'B'), is meant to be ignorable. They enhance functionality or improve performance if understood, but an older tool that does not understand them can safely ignore and correctly operate. Another extension, by the way, is TREE extension, which holds the cache-tree to speed up write-tree operation. I think everybody's git would understand them by now. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
