Enjoy.
from the NEWS file:
changes in sbcl-0.8.12 relative to sbcl-0.8.11:
* minor incompatible change: the system no longer provides
optimization hints (conditions which are TYPEP
SB-EXT:COMPILER-NOTE) for conforming code in default compilation
mode; these hints are still emitted when higher SPEED optimization
is requested.
* new contrib module: a sampling profiler (profiling by statistical
sampling, rather than by instrumenting functions) is available as
the SB-SPROF contrib. (thanks to Gerd Moellmann and Juho Snellman)
* the behaviour of the standard function ED is now customizeable by
third parties through a hook variable: see ED's documentation
string for information on the protocol.
* the compiler no longer emits efficiency notes for (FUNCALL X)
when the type of X is uncertain under default optimization
settings.
* fixed bug 276: mutating a binding of a specialized parameter to a
method to something that is not TYPEP the specializer is now
possible.
* fixed bugs 45d and 118: DOUBLE-FLOAT[-NEGATIVE]-EPSILON now
exhibit the required behaviour on the x86 platform. (thanks to
Peter van Eynde, Eric Marsden and Bruno Haible)
* fixed bug 335: ATANH now computes the inverse hyperbolic tangent
even for difficult arguments. (reported by Peter Graves)
* fixed bug 141a: the backquote printer now descends quoted
structure.
* fixed another bug in backquote printing: no more destructive
modification of the form's list structure. (reported by Brian
Downing)
* fixed bug in INTERRUPT-THREAD: pin the function, so that it cannot
move between its address being taken and the call to
interrupt_thread, fixing a crashing race condition.
* the SB-POSIX contrib implementation has been adjusted so that it
no longer exhibits ridiculously poor performance when constructing
instances corresponding to C structs.
