+ * bug fix: source-locations of DEFGENERIC forms weren't getting recorded
+ properly. (lp#384801)
+ * bug fix: (COERCE X '(SIMPLE-VECTOR 5)) and similar coercions to vectors
+ of specified length could confuse the type derivation in unsafe code.
+ (lp#655872)
+ * bug fix: SB-POSIX:FORK now signals an error if an attempt to
+ fork with multiple Lisp threads running is made on every platform,
+ not just Darwin. (lp#451111)
+ * bug fix: SB-BSD-SOCKETS and SB-SIMPLE-STREAMS could leave stale finalizers
+ around when core was saved, which could cause undefined behaviour when the
+ core was reified.
+ * bug fix: Allow UNTRACE of functions that are no longer defined
