  * Improved handling of views, labels and branches in git-p4 (in contrib).
 
+ * "git-p4" (in contrib) suffered from unnecessary merge conflicts when
+   p4 expanded the embedded $RCS$-like keywords; it can be now told to
+   unexpand them.
+
+ * Some "git-svn" updates.
+
  * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
    support incremental imports.
 
+ * The configuration mechanism learned an "include" facility; an
+   assignment to the include.path pseudo-variable causes the named
+   file to be included in-place when Git looks up configuration
+   variables.
+
  * "git am" learned to pass "-b" option to underlying "git mailinfo", so
    that bracketed string other than "PATCH" at the beginning can be kept.

  * The test suite supports the new "test_pause" helper function.
 
+ * Parallel to the test suite, there is a beginning of performance

  * t/Makefile is adjusted to prevent newer versions of GNU make from
    running tests in seemingly random order.
