>   value for the HEAD symbolic ref when the namespace feature is in
>   use, which has been corrected.
>
> * "git am -i --resolved" segfaulted after trying to see a commit as
>   if it were a tree, which has been corrected.
>
> * "git bundle verify" needs to see if prerequisite objects exist in
>   the receiving repository, but the command did not check if we are
>   in a repository upfront, which has been corrected.
>
> * "git merge --squash" is designed to update the working tree and the
>   index without creating the commit, and this cannot be countermanded
>   by adding the "--commit" option; the command now refuses to work
>   when both options are given.
>
> * The data collected by fsmonitor was not properly written back to
>   the on-disk index file, breaking t7519 tests occasionally, which
>   has been corrected.
>
> * Update to Unicode 12.1 width table.
>
> * The command line to invoke a "git cat-file" command from inside
>   "git p4" was not properly quoted to protect a caret and running a
>   broken command on Windows, which has been corrected.
>
> * "git request-pull" learned to warn when the ref we ask them to pull
>   from in the local repository and in the published repository are
>   different.
>
> * When creating a partial clone, the object filtering criteria is
>   recorded for the origin of the clone, but this incorrectly used a
>   hardcoded name "origin" to name that remote; it has been corrected
>   to honor the "--origin <name>" option.
>
> * "git fetch" into a lazy clone forgot to fetch base objects that are
>   necessary to complete delta in a thin packfile, which has been
>   corrected.
>
> * The filter_data used in the list-objects-filter (which manages a
>   lazily sparse clone repository) did not use the dynamic array API
>   correctly---'nr' is supposed to point at one past the last element
>   of the array in use.  This has been corrected.
>
> * The description about slashes in gitignore patterns (used to
>   indicate things like "anchored to this level only" and "only
>   matches directories") has been revamped.
>
> * The URL decoding code has been updated to avoid going past the end
>   of the string while parsing %-<hex>-<hex> sequence.
>
> * The list of for-each like macros used by clang-format has been
>   updated.
>
> * "git push --atomic" that goes over the transport-helper (namely,
>   the smart http transport) failed to prevent refs to be pushed when
>   it can locally tell that one of the ref update will fail without
>   having to consult the other end, which has been corrected.
>
> * "git clean" silently skipped a path when it cannot lstat() it; now
>   it gives a warning.
>
> * A codepath that reads from GPG for signed object verification read
>   past the end of allocated buffer, which has been fixed.
>
> * "git rm" to resolve a conflicted path leaked an internal message
>   "needs merge" before actually removing the path, which was
>   confusing.  This has been corrected.
>
> * The "git clone" documentation refers to command line options in its

>   to the command to be run in each submodule correctly, when the
>   "--recursive" option was in use.

>   support to clear cruft in the progress output.

> * The code to parse scaled numbers out of configuration files has
>   been made more robust and also easier to follow.
>
> * An incorrect list of options was cached after command line

>   a repository outside one), which has been corrected.

>   corrected.
>
> * Code clean-up to avoid signed integer overlaps during binary search.
>
> * "git checkout -p" needs to selectively apply a patch in reverse,
>   which did not work well.
