Now we do. + + * When "git merge" detects a path that is renamed in one history + while the other history deleted (or modified) it, it now reports + both paths to help the user understand what is going on in the two + histories being merged. + + * The <url> part in "http.<url>.<variable>" configuration variable + can now be spelled with '*' that serves as wildcard. + E.g. "http.https://*.example.com.proxy" can be used to specify the + proxy used for https://a.example.com, https://b.example.com, etc., + i.e. any host in the example.com domain. + + * "git tag" did not leave useful message when adding a new entry to + reflog; this was left unnoticed for a long time because refs/tags/* + doesn't keep reflog by default. + + * The "negative" pathspec feature was somewhat more cumbersome to use + than necessary in that its short-hand used "!" which needed to be + escaped from shells, and it required "exclude from what?" specified. + + * The command line options for ssh invocation needs to be tweaked for + some implementations of SSH (e.g. PuTTY plink wants "-P <port>" + while OpenSSH wants "-p <port>" to specify port to connect to), and + the variant was guessed when GIT_SSH environment variable is used + to specify it.

This is not a problem in practice + because you do not want to delete the branch you are currently on, + but caused renaming of the current branch to something else not to + be logged in a useful way. + + +Performance, Internal Implementation, Development Support etc. + + * The code to list branches in "git branch" has been consolidated + with the more generic ref-filter API. + + * Resource usage while enumerating refs from alternate object store + has been optimized to help receiving end of "push" that hosts a + repository with many "forks". + + * The gitattributes machinery is being taught to work better in a + multi-threaded environment. + + * "git rebase -i" starts using the recently updated "sequencer" code. + + * Code and design clean-up for the refs API. + + * The preload-index code has been taught not to bother with the index + entries that are paths that are not checked out by "sparse checkout". + + * Some warning() messages from "git clean" were updated to show the + errno from failed system calls. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.12 +----------------- + +Unless otherwise noted, all the fixes since v2.9 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * "git repack --depth=<n>" for a long time busted the specified depth + when reusing delta from existing packs.
