learned to show a few more traits of objects that can be learned by
the object_info API.
+ * "git rebase -i" learned to re-execute a command given with 'exec'
+ to run after it failed the last time.
+
+ * "git diff --color-moved-ws" updates.
+
+ * Custom userformat "log --format" learned %S atom that stands for
+ the tip the traversal reached the commit from, i.e. --source.

Performance, Internal Implementation, Development Support etc.
"--stress" option.
(merge fb7d1e3ac8 sg/stress-test later to maint).
+ * Documentation/Makefile is getting prepared for manpage
+ localization.
+
+ * "git fetch-pack" now can talk the version 2 protocol.
+
+ * sha-256 hash has been added and plumbed through the code to allow
+ building Git with the "NewHash".
+
+ * Debugging help for http transport.
+
+ * "git fetch --deepen=<more>" has been corrected to work over v2
+ protocol.
+
+ * The code to walk tree objects has been taught that we may be

Fixes since v2.20
-----------------
corrected.
(merge 5bdece0d70 js/gc-repack-close-before-remove later to maint).
+ * The code to drive GIT_EXTERNAL_DIFF command relied on the string
+ returned from getenv() to be non-volatile, which is not true, that
+ has been corrected.
+ (merge 6776a84dae kg/external-diff-save-env later to maint).
+
+ * There were many places the code relied on the string returned from
+ getenv() to be non-volatile, which is not true, that have been
+ corrected.
+ (merge 0da0e9268b jk/save-getenv-result later to maint).
+
+ * The v2 upload-pack protocol implementation failed to honor
+ hidden-ref configuration, which has been corrected.
+ (merge e20b4192a3 jk/proto-v2-hidden-refs-fix later to maint).
+
+ * "git fetch --recurse-submodules" may not fetch the necessary commit
+ that is bound to the superproject, which is getting corrected.
+ (merge be76c21282 sb/submodule-recursive-fetch-gets-the-tip later to maint).
+
+ * "git rebase" internally runs "checkout" to switch between branches,
+ and the command used to call the post-checkout hook, but the
+ reimplementation stopped doing so, which is getting fixed.
+
+ * "git add -e" got confused when the change it wants to let the user
+ edit is smaller than the previous change that was left over in a
+ temporary file.
+ (merge fa6f225e01 js/add-e-clear-patch-before-stating later to maint).
