* "git merge-base" optimization.
66
67
+ * The limit_list() function that is one of the core part of the
68
+ revision traversal infrastructure has been optimized by replacing
69
+ its use of linear list with priority queue.
70

71
+ * In a lazy clone, "git cherry" and "git grep" often fetch necessary
72
+ blob objects one by one from promisor remotes. It has been corrected
73
+ to collect necessary object names and fetch them in bulk to gain
74
+ reasonable performance.
75
+
76
+ * The logic to determine that branches in an octopus merge are
77
+ independent has been optimized.
78
+
79
+ * The consistency checks for the files reference backend have been updated
80
+ to skip lock files earlier, avoiding unnecessary parsing of
81
+ intermediate files.
82
+
83
+ * The negotiation tip options in "git fetch" have been reworked to
84
+ allow requiring certain refs to be sent as "have" lines, and to
85
+ restrict negotiation to a specific set of refs.
86
+
87
+ * The repacking code has been refactored and compaction of MIDX layers
88
+ have been implemented, and incremental strategy that does not require
89
+ all-into-one repacking has been introduced.
90

91
+ * ODB transaction interface is being reworked to explicitly handle
92
+ object writes.
93
+
94
+ * Add a new odb "in-memory" source that is meant to only hold
95
+ tentative objects (like the virtual blob object that represents the
96
+ working tree file used by "git blame").
97
+
98
+ * Many uses of the_repository has been updated to use a more
99
+ appropriate struct repository instance in setup.c codepath.
