  * "git merge-base" optimization.
 
+ * The limit_list() function that is one of the core part of the
+   revision traversal infrastructure has been optimized by replacing
+   its use of linear list with priority queue.
+
+ * In a lazy clone, "git cherry" and "git grep" often fetch necessary
+   blob objects one by one from promisor remotes.  It has been corrected
+   to collect necessary object names and fetch them in bulk to gain
+   reasonable performance.
+
+ * The logic to determine that branches in an octopus merge are
+   independent has been optimized.
+
+ * The consistency checks for the files reference backend have been updated
+   to skip lock files earlier, avoiding unnecessary parsing of
+   intermediate files.
+
+ * The negotiation tip options in "git fetch" have been reworked to
+   allow requiring certain refs to be sent as "have" lines, and to
+   restrict negotiation to a specific set of refs.
+
+ * The repacking code has been refactored and compaction of MIDX layers
+   have been implemented, and incremental strategy that does not require
+   all-into-one repacking has been introduced.
+
+ * ODB transaction interface is being reworked to explicitly handle
+   object writes.
+
+ * Add a new odb "in-memory" source that is meant to only hold
+   tentative objects (like the virtual blob object that represents the
+   working tree file used by "git blame").
+
+ * Many uses of the_repository has been updated to use a more
+   appropriate struct repository instance in setup.c codepath.
