The meaning + of the option has been changed to always show "HEAD" regardless of + what filtering will be applied to any other ref. + + This is a backward incompatible change and might cause breakages to + people's existing scripts. + + * "git show -s" was less discoverable than it should have been. It + now has a natural synonym "git show --no-patch". + + * "git check-mailmap" is a new command that lets you map usernames + and e-mail addresses through the mailmap mechanism, just like many + built-in commands do. + + * "git name-rev" learned to name an annotated tag object back to its + tagname; "git name-rev $(git rev-parse v1.0.0)" gives "tags/v1.0.0", + for example. + + * "git cat-file --batch-check=<format>" is added, primarily to allow + on-disk footprint of objects in packfiles (often they are a lot + smaller than their true size, when expressed as deltas) to be + reported. + + * "git rebase [-i]" used to leave just "rebase" as its reflog messages + for some operations.

Now the variable defaults to "auto". + + * On Cygwin, "cygstart" is now recognised as a possible way to start + a web browser (used in "help -w" and "instaweb" among others). + + * "git status" learned status.branch and status.short configuration + variables to use --branch and --short options by default (override + with --no-branch and --no-short options from the command line). + + * "git cmd <name>", when <name> happens to be a 40-hex string, + directly uses the 40-hex string as an object name, even if a ref + "refs/<some hierarchy>/<name>" exists. This disambiguation order + is unlikely to change, but we should warn about the ambiguity just + like we warn when more than one refs/ hierarchies share the same + name. + + * "git rebase" learned "--[no-]autostash" option to save local + changes instead of refusing to run (to which people's normal + response was to stash them and re-run). This introduced a corner + case breakage to "git am --abort" but it has been fixed. + + * Instead of typing four capital letters "HEAD", you can say "@" now, + e.g. "git log @". + + * "check-ignore" (new feature since 1.8.2) has been updated to work + more like "check-attr" over bidi-pipes. + + * "git describe" learned "--first-parent" option to limit its closest + tagged commit search to the first-parent chain. + + * "git merge foo" that might have meant "git merge origin/foo" is + diagnosed with a more informative error message. + + * "git log -L<line>,<range>:<filename>" has been added.

The code to support the feature was + still in a function but the caller was changed not to call it 5 + years ago, breaking that feature and leaving the supporting code + unreachable. The dead code has been removed. + + * "git pack-refs" that races with new ref creation or deletion have + been susceptible to lossage of refs under right conditions, which + has been tightened up. + + * We read loose and packed rerferences in two steps, but after + deciding to read a loose ref but before actually opening it to read + it, another process racing with us can unlink it, which would cause + us to barf.
