See: SB-EXT:*USERINIT-PATHNAME-FUNCTION* + and SB-EXT:*SYSINIT-PATHNAME-FUNCTION*. + * enhancement: SB-EXT:MAKE-THREAD accepts an argument list designator for + the thunk, as a keyword argument, :arguments. + * enhancement: constraint propagation is simplified (and sped up) when + COMPILATION-SPEED > SPEED. + * optimization: extracting bits of a single-float on x86-64 has been + optimized. (lp#555201) + * meta-optimization: improved compilation speed, especially for large + functions. (lp#792363 and lp#394206) + * bug fix: bound derivation for floating point operations is now more + careful about rounding possibly closing open bounds. (lp#793771) + * bug fix: SB-POSIX:SYSCALL-ERROR's argument is now optional. (accidental + backwards incompatible change in 1.0.48.27) + * bug fix: occasional debugger errors in when a type-error occured in a + function with dynamic-extent &rest list. + * bug fix: &optional and &key supplied-p arguments in DEFSTRUCT + boa-construtors can be used to initialized structure slots. + * bug fix: FMAKUNBOUND removes the MACRO-FUNCTION, should one exist. + (lp#795705, regression) + * bug fix: DIRECTORY works better on logical pathnames. + * bug fix: RUN-PROGRAM no longer fails spuriously when argument strings + are of the order of ARRAY-TOTAL-SIZE-LIMIT.
