We will use the "simple" semantics that pushes the +current branch to the branch with the same name, only when the current +branch is set to integrate with that remote branch.

The description was clarified by defining + how the title is decided and rewording the casual mention of "first + line" to "title". + + * "git cvsimport" did not thoroughly cleanse tag names that it + inferred from the names of the tags it obtained from CVS, which + caused "git tag" to barf and stop the import in the middle. + + * Earlier we made the diffstat summary line that shows the number of + lines added/deleted localizable, but it was found irritating having + to see them in various languages on a list whose discussion language + is English, and this change has been reverted. + + * "git fetch --all", when passed "--no-tags", did not honor the + "--no-tags" option while fetching from individual remotes (the same + issue existed with "--tags", but the combination "--all --tags" makes + much less sense than "--all --no-tags"). + + * "git fetch" over http had an old workaround for an unlikely server + misconfiguration; it turns out that this hurts debuggability of the + configuration in general, and has been reverted. + + * "git fetch" over http advertised that it supports "deflate", which + is much less common, and did not advertise the more common "gzip" on + its Accept-Encoding header. + + * "git fetch" over the dumb-http revision walker could segfault when + curl's multi interface was used. + + * "git gc --auto" notified the user that auto-packing has triggered + even under the "--quiet" option. + + * After "gitk" showed the contents of a tag, neither "Reread + references" nor "Reload" updated what is shown as the + contents of it when the user overwrote the tag with "git tag -f". + + * |
