• Many Porcelain commands that internally use the merge machinery were taught to consistently honor the diff.algorithm configuration.

• A few descriptions in “git show-ref -h” have been clarified.

• A ‘P’ command to “git add -p” that passes the patch hunk to the pager has been added.

• “git grep -W” omits blank lines that follow the found function at the end of the file, just like it omits blank lines before the next function.

• The value of http.proxy can have “path” at the end for a socks proxy that listens to a unix-domain socket, but we started to discard it when we taught proxy auth code path to use the credential helpers, which has been corrected.

• The code paths to compact multiple reftable files have been updated to correctly deal with multiple compaction triggering at the same time.

• Support to specify ref backend for submodules has been enhanced.

• “git svn” has been taught about svn:global-ignores property recent versions of Subversion has.

• The default object hash and ref backend format used to be settable only with explicit command line option to “git init” and environment variables, but now they can be configured in the user’s global and system wide configuration.

• “git send-email” learned “–translate-aliases” option that reads addresses from the standard input and emits the result of applying aliases on them to the standard output.

• ‘git for-each-ref’ learned a new “–format” atom to find the branch that the history leading to a given commit “%(is-base:<commit>)” is likely based on.

• The command line prompt support used to be littered with bash-isms, which has been corrected to work with more shells.

• Support for the RUNTIME_PREFIX feature has been added to z/OS port.

• “git send-email” learned “–mailmap” option to allow rewriting the recipient addresses.

• “git mergetool” learned to use VSCode as a merge backend.

• “git pack-redundant” has been marked for removal in Git 3.0.

• One-line messages to “die” and other helper functions will get LF added by these helper functions, but many existing messages had an unnecessary LF at the end, which have been corrected.

• The “scalar clone” command learned the “–no-tags” option.

• The environment GIT_ADVICE has been intentionally kept undocumented to discourage its use by interactive users. Add documentation to help tool writers.
