+ * minor incompatible change: the :SB-LDB feature is now enabled by
+ default, and DISABLE-DEBUGGER and ENABLE-DEBUGGER also affect
+ the low-level debugger.
+ * enchancement: RUN-PROGRAM is now able to extract the file-descriptor
+ from SYNONYM-STREAM and TWO-WAY-STEAMS provided they can be decomposed
+ down to an SB-SYS:FD-STREAM, allowing direct communication in
+ more cases. Temporary files and pipes are still used as a fallback
+ strategy.
+ * thread-safety: DECODE-UNIVERSAL-TIME & GET-DECODED-TIME depended
+ on the non-reentrant C functions localtime(3) and gmtime(3).
+ * bug fix: global optimization policy was not visible in LOCALLY and
+ MACROLET forms.
+ * bug fix: class objects can be used as specializers in methods.
