Foreign Interface
+ * "git p4" has been moved out of contrib/ area.
Performance
+ * "git apply" had some memory leaks plugged.
+
+ * Setting up a revision traversal with many starting points was
+ inefficient as these were placed in a date-order priority queue
+ one-by-one. Now they are collected in the queue unordered first,
+ and sorted immediately before getting used.
Internal Implementation (please report possible regressions)
+ * "git rev-parse --show-prefix" used to emit nothing when run at the
+ top-level of the working tree, but now it gives a blank line.
+
* Minor memory leak during unpack_trees (hence "merge" and "checkout"
to check out another branch) has been plugged.
releases are contained in this release (see release notes to them for
details).
+ * "git fetch" that recurses into submodules on demand did not check
+ if it needs to go into submodules when non branches (most notably,
+ tags) are fetched.
+ (merge a6801ad jl/maint-submodule-recurse-fetch later to maint).
+
+ * "git blame" started missing quite a few changes from the origin
+ since we stopped using the diff minimalization by default in v1.7.2
+ era.
+ (merge 059a500 jc/maint-blame-minimal later to maint).
+
+ * "log -p --graph" used with "--stat" had a few formatting error.
+ (merge e2c5966 lp/maint-diff-three-dash-with-graph later to maint).
+
+ * Giving "--continue" to a conflicted "rebase -i" session skipped a
+ commit that only results in changes to submodules.
+ (merge a6754cd jk/rebase-i-submodule-conflict-only later to maint).
+
* When PATH contains an unreadable directory, alias expansion code
did not kick in, and failed with an error that said "git-subcmd"
was not found.
