+  * enhancement: "fixed objects" can now be stack-allocated on PPC.
+  * enhancement: WITH-PINNED-OBJECTS no longer conses on PPC/GENCGC.
+  * enhancement: (sb-introspect:find-definition-sources-by-name x :vop) now
+    also returns VOPs which do not translate any functions.
+  * enhancement: better type derivation for APPEND, NCONC, LIST.
+    (lp#538957)
+  * bug fix: type derivation for LOG{AND,IOR,XOR} scales linearly instead
+    of quadratically with the size of the input in the worst case.
+    (lp#1096444)
   * bug fix: handle errors when initializing *default-pathname-defaults*,
     sb-ext:*runtime-pathname*, sb-ext:*posix-argv* on startup, like character
     decoding errors, or directories being deleted.
+  * bug fix: Loading a core with a discontiguous dynamic space now correctly
+    computes the amount of dynamic space used.
+  * bug fix: disassembler missing ",8" on SHLD
+  * optimization: faster ISQRT on fixnums and small bignums
+  * optimization: faster and smaller INTEGER-LENGTH on fixnums on x86-64.
