Arguably, in a + repository used for active development, such defaulting would not + be very useful as the tip of branch is typically not tagged, but it + is better to be consistent. + (merge 2bd0706 sg/describe-contains later to maint). + + * The client side codepaths in "git push" have been cleaned up + and the user can request to perform an optional "signed push", + i.e. sign only when the other end accepts signed push. + (merge 68c757f db/push-sign-if-asked later to maint). + + * Because the configuration system does not allow "alias.0foo" and + "pager.0foo" as the configuration key, the user cannot use '0foo' + as a custom command name anyway, but "git 0foo" tried to look these + keys up and emitted useless warnings before saying '0foo is not a + git command'. These warning messages have been squelched. + (merge 9e9de18 jk/fix-alias-pager-config-key-warnings later to maint). + + * "git rev-list" does not take "--notes" option, but did not complain + when one is given. + (merge 2aea7a5 jk/rev-list-has-no-notes later to maint). + + * When re-priming the cache-tree opportunistically while committing + the in-core index as-is, we mistakenly invalidated the in-core + index too aggressively, causing the experimental split-index code + to unnecessarily rewrite the on-disk index file(s). + (merge 475a344 dt/commit-preserve-base-index-upon-opportunistic-cache-tree-update later to maint). + + * "git archive" did not use zip64 extension when creating an archive + with more than 64k entries, which nobody should need, right ;-)? + (merge 88329ca rs/archive-zip-many later to maint). + + * The code in "multiple-worktree" support that attempted to recover + from an inconsistent state updated an incorrect file. + (merge 82fde87 nd/fixup-linked-gitdir later to maint). + + * On case insensitive systems, "git p4" did not work well with client + specs. + + * "git init empty && git -C empty log" said "bad default revision 'HEAD'", + which was found to be a bit confusing to new users. + (merge ce11360 jk/log-missing-default-HEAD later to maint). + + * Recent versions of scripted "git am" has a performance regression in + "git am --skip" codepath, which no longer exists in the built-in + version on the 'master' front.
