(thanks to Nikodemus Siivola) * bug fix: buffered :DIRECTION :IO streams are less likely to become confused about their position. (thanks to Adam Warner and Gerd Moellmann) + * 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 + expressions involving CONS and NOT many times has been improved. + (reported by Paul Dietz) + * ASDF-INSTALL bug fix: now parses *PROXY* properly. (thanks to + Sean Ross) + * 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 + to cause DIVIDE-BY-ZERO or FLOATING-POINT-OVERFLOW errors. + ** extremely complex negations of CONS types were not being + sufficiently canonicalized, leading to inconsistencies in + SUBTYPEP. + ** 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. planned incompatible changes in 0.8.x: * (not done yet, but planned:) When the profiling interface settles
