It has been + corrected. + + * A change back in version 2.7 to "git branch" broke display of a + symbolic ref in a non-standard place in the refs/ hierarchy (we + expect symbolic refs to appear in refs/remotes/*/HEAD to point at + the primary branch the remote has, and as .git/HEAD to point at the + branch we locally checked out). + + * A partial rewrite of "git submodule" in the 2.7 timeframe changed + the way the gitdir: pointer in the submodules point at the real + repository location to use absolute paths by accident. This has + been corrected. + + * "git commit" misbehaved in a few minor ways when an empty message + is given via -m '', all of which has been corrected. + + * Support for CRAM-MD5 authentication method in "git imap-send" did + not work well. + + * Upcoming OpenSSL 1.1.0 will break compilation b updating a few APIs + we use in imap-send, which has been adjusted for the change. + (merge 1245c74 ky/imap-send-openssl-1.1.0 later to maint). + + * The socks5:// proxy support added back in 2.6.4 days was not aware + that socks5h:// proxies behave differently. + + * "git config" had a codepath that tried to pass a NULL to + printf("%s"), which nobody seems to have noticed. + + * On Cygwin, object creation uses the "create a temporary and then + rename it to the final name" pattern, not "create a temporary, + hardlink it to the final name and then unlink the temporary" + pattern. + + This is necessary to use Git on Windows shared directories, and is + already enabled for the MinGW and plain Windows builds. It also + has been used in Cygwin packaged versions of Git for quite a while. + See http://thread.gmane.org/gmane.comp.version-control.git/291853 + + * "merge-octopus" strategy did not ensure that the index is clean + when merge begins. + + * When "git merge" notices that the merge can be resolved purely at + the tree level (without having to merge blobs) and the resulting + tree happens to already exist in the object store, it forgot to + update the index, which lead to an inconsistent state for later + operations. + + * "git submodule" reports the paths of submodules the command + recurses into, but this was incorrect when the command was not run + from the root level of the superproject. + (merge 2ab5660 sb/submodule-path-misc-bugs later to maint). + + * The "user.useConfigOnly" configuration variable makes it an error + if users do not explicitly set user.name and user.email.
