+   The commands learned "--no-shown-forced-updates" option to disable

+
+ * Two new commands "git switch" and "git restore" are introduced to

+   "checking out paths out of the index and/or a tree-ish to work on
+   advancing the current history" out of the single "git checkout"
+   command.
+
+ * "git branch --list" learned to always output the detached HEAD as
+   the first item (when the HEAD is detached, of course), regardless
+   of the locale.
+
+ * The conditional inclusion mechanism learned to base the choice on
+   the branch the HEAD currently is on.
+
+ * "git rev-list --objects" learned with "--no-object-names" option to
+   squelch the path to the object that is used as a grouping hint for
