   * enhancement: run-program no longer decodes and re-encodes environment when
     :environment argument is not provided. (lp#985904)
+  * optimization: On x86-64, code alignment of block headers is done with
+    multi-byte NOPs now instead of repetitions of the single-byte NOP.
+  * optimization: MAP-INTO is substantially faster when the target sequence is
+    of unknown type; mapping into lists is no longer O(N^2). (thanks to James
+    M. Lawrence)
+  * optimization: SB-SEQUENCE:DOSEQUENCE is faster on vectors of unknown
+    element type, and vectors that aren't SIMPLE-ARRAYs.
   * bug fix: potential for infinite recursion during compilation of CLOS slot
     typechecks when dependency graph had loops. (lp#1001799)
   * bug fix: error forms reported with some program-errors were not escaped
