* bug fix: Pretty printing backquoted forms with unquotations in the
argument list position of various code constructs such as LAMBDA
now works correctly. (reported by Paul Dietz)
+ * bug fix: Pretty printing unquotations no longer loses all
+ stream position information.
* optimization: performance of string output streams is now less
poor for multiple small sequence writes.
* optimization: performance of CSUBTYPEP in the presence of complex
* SB-SIMPLE-STREAMS enhancement: simple-streams can now be used as
streams for the REPL, for the debugger, and so on. (thanks to
David Licteblau)
+ * DEFINE-CODITION is more efficient. (thanks to Brian Mastenbrook)
* fixed some bugs revealed by Paul Dietz' test suite:
** the value of the :REHASH-THRESHOLD argument to MAKE-HASH-TABLE
is ignored if it is too small, rather than propagating through
** extremely complex negations of CONS types were not being
sufficiently canonicalized, leading to inconsistencies in
SUBTYPEP.
- ** VALUES tranformer lost derive type.
+ ** VALUES tranformer lost derived type.

+changes in sbcl-0.8.8 relative to sbcl-0.8.7:
+ * bug fix: DECODE-UNIVERSAL-TIME now accepts timezone arguments with
+ second-resolution: integer multiples of 1/3600 between -24 and 24.
+ (thanks to Vincent Arkesteijn)
+ * optimization: implemented multiplication as a modular
+ (UNSIGNED-BYTE 32) operation on the x86 backend.
+ * optimization: SEARCH on simple-base-strings can now be open-coded.
+ (see also contrib/compiler-extras.lisp for inspiration for
+ teaching the compiler about the Boyer-Moore algorithm).
+ * bug fix: functions =, /=, <, <=, >, >= did not check the argument
+ type when called with 1 argument; PEEK-CHAR checked type of
+ PEEK-TYPE only after having read first character from a
+ stream. (reported by Peter Graves)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** in stack analysis liveness information is propagated from
+ non-local entry points.
+ ** pathwise CAST removing failed when the CAST node did not start
+ a block.
+ ** INPUT-STREAM-P, OUTPUT-STREAM-P, STREAM-ELEMENT-TYPE and
+ OPEN-STREAM-P signal a TYPE-ERROR if their argument is not a
+ stream.
+ ** LOAD-LOGICAL-PATHNAME-TRANSLATIONS returns NIL if the logical
+ host is already defined.
+ ** RENAME-FILE works on streams instead of signalling an internal
+ type error.
+ ** PEEK-CHAR now uses the current readtable when determining
+ whether a character is whitespace.
