used in a way similar to existing "--is-bare-repository" and
friends.
+ * "git describe --match <pattern>" has been taught to play well with
+ the "--all" option.
+
+ * "git branch" learned "-c/-C" to create a new branch by copying an
+ existing one.
+
+ * Some commands (most notably "git status") makes an opportunistic
+ update when performing a read-only operation to help optimize later
+ operations in the same repository. The new "--no-optional-locks"
+ option can be passed to Git to disable them.

Performance, Internal Implementation, Development Support etc.
expect failures under a limited stack situation. This has been
fixed.
+ * Many codepaths have been updated to squelch -Wimplicit-fallthrough
+ warnings from Gcc 7 (which is a good code hygiene).
+
+ * Add a helper for DLL loading in anticipation for its need in a
+ future topic RSN.
+
+ * "git status --ignored", when noticing that a directory without any
+ tracked path is ignored, still enumerated all the ignored paths in
+ the directory, which is unnecessary. The codepath has been
+ optimized to avoid this overhead.
+
+ * The final batch to "git rebase -i" updates to move more code from
+ the shell script to C has been merged.
+
+ * Operations that do not touch (majority of) packed refs have been
+ optimized by making accesses to packed-refs file lazy; we no longer
+ pre-parse everything, and an access to a single ref in the
+ packed-refs does not touch majority of irrelevant refs, either.
Also contains various documentation updates and code clean-ups.
alternate object stores overrun the end of the string.
(merge f0f7bebef7 jk/info-alternates-fix later to maint).
+ * "git describe --match" learned to take multiple patterns in v2.13
+ series, but the feature ignored the patterns after the first one
+ and did not work at all. This has been fixed.
+ (merge da769d2986 jk/describe-omit-some-refs later to maint).
+
+ * "git filter-branch" cannot reproduce a history with a tag without
+ the tagger field, which only ancient versions of Git allowed to be
+ created. This has been corrected.
+ (merge b2c1ca6b4b ic/fix-filter-branch-to-handle-tag-without-tagger later to maint).
+
+ * "git cat-file --textconv" started segfaulting recently, which
+ has been corrected.
+ (merge cc0ea7c9e5 jk/diff-blob later to maint).
+
+ * The built-in pattern to detect the "function header" for HTML did
+ not match <H1>..<H6> elements without any attributes, which has
+ been fixed.
+ (merge 9c03caca2c ik/userdiff-html-h-element-fix later to maint).
+
+ * "git mailinfo" was loose in decoding quoted printable and produced
+ garbage when the two letters after the equal sign are not
+ hexadecimal. This has been fixed.
+ (merge c8cf423eab rs/mailinfo-qp-decode-fix later to maint).
+
+ * The machinery to create xdelta used in pack files received the
+ sizes of the data in size_t, but lost the higher bits of them by
+ storing them in "unsigned int" during the computation, which is
+ fixed.
+
+ * The delta format used in the packfile cannot reference data at
+ offset larger than what can be expressed in 4-byte, but the
+ generator for the data failed to make sure the offset does not
+ overflow. This has been corrected.
+
+ * The documentation for '-X<option>' for merges was misleadingly
+ written to suggest that "-s theirs" exists, which is not the case.
+ (merge c25d98b2a7 jc/merge-x-theirs-docfix later to maint).
+
+ * "git fast-export" with -M/-C option issued "copy" instruction on a
+ path that is simultaneously modified, which was incorrect.
+ (merge b3e8ca89cf jt/fast-export-copy-modify-fix later to maint).
+
+ * Many codepaths have been updated to squelch -Wsign-compare
+ warnings.
+ (merge 071bcaab64 rj/no-sign-compare later to maint).
+
+ * Memory leaks in various codepaths have been plugged.
+ (merge 4d01a7fa65 ma/leakplugs later to maint).
+
+ * Recent versions of "git rev-parse --parseopt" did not parse the
+ option specification that does not have the optional flags (*=?!)
+ correctly, which has been corrected.
+ (merge a6304fa4c2 bc/rev-parse-parseopt-fix later to maint).
+
* Other minor doc, test and build updates and code cleanups.
