+ * enhancement: implicit generic function creation now signals a
+ specific style-warning IMPLICIT-GENERIC-FUNCTION-WARNING, which
+ users can bind handlers for and muffle around calls to LOAD.
+ * enhancement: RUN-PROGRAM allows unicode arguments and environments
+ to be used (using the default stream external format), and allows
+ non-simple strings to be used. (thanks to Harald Hanche-Olsen)
+ * optimization: COPY-SEQ, FILL, and SUBSEQ are 30-80% faster for
+ strings and vectors whose element-type or simplicity is not fully
+ known at compile-time.
+ * optimization: STRING-TRIM and related functions no longer allocate
+ a new string when no trimming needs to be performed. These functions
+ are also faster than before when the input string has been declared
+ as a simple-string.
+ * optimization: READ-SEQUENCE on simple-strings is up to 80% faster.
+ * optimization: READ-LINE is significantly faster for files containing
+ long lines.
+ * optimization: non-open coded uses of character comparison operators
+ (e.g. char=) no longer cons when called with more than one parameter
+ on platforms supporting dynamic-extent allocation.
+ * bug fix: READ-SEQUENCE on composite stream wrapping a Gray stream
+ with STREAM-ELEMENT-TYPE (UNSIGNED-BYTE 8) signalled an error.
+ * bug fix: COPY-SEQ on lists did not signal a type-error on improper
+ lists in safe code.
