>From the NEWS file in the distribution:
changes in sbcl-1.0.8 relative to sbcl-1.0.7:
  * enhancement: experimental macro SB-EXT:COMPARE-AND-SWAP provides
    atomic compare-and-swap operations on threaded platforms.
  * enhancement: experimental function SB-EXT:RESTRICT-COMPILER-POLICY
    allows assining a global minimum value to optimization qualities
    (overriding proclamations and declarations).
  * enhancement: closed over variables can be stack-allocated on x86
    and x86-64.
  * performance bug fix: GETHASH and (SETF GETHASH) are once again
    non-consing.
  * optimization: slot definition lookup is now O(1). This speeds up
    eg. SLOT-VALUE and (SETF SLOT-VALUE) with variable slot names.
  * optimization: STRING-TO-OCTETS is now up to 60% faster for UTF-8.
  * optimization: ASSOC and MEMBER can now be open-coded for all
    combinations of keyword arguments when second argument is constant
    and SPEED >= SPACE. In other cases a specialized version is
    selected.
  * bug fix: using obsoleted structure instances with TYPEP and
    generic functions now signals a sensible error.
  * bug fix: threads waiting on GET-FOREGROUND can be interrupted.
    (reported by Kristoffer Kvello)
  * bug fix: backtrace construction is now more careful when making
    lisp-objects from pointers on the stack, to avoid creating bogus
    objects that can be seen by the GC.
  * bug fix: defaulting of values in contexts expecting more than 7
    variables now works on x86-64.  (reported by Christopher Laux)
  * bug fix: modifications to packages (INTERN, EXPORT, etc) are now
    thread safe.
  * bug fix: (SETF SYMBOL-PLIST) no longer allows assigning a non-list
    as the property-list of a symbol.
  * bug fix: DEFMETHOD forms with CALL-NEXT-METHOD in the method body,
    in EVAL-WHEN forms with both :COMPILE-TOPLEVEL and :LOAD-TOPLEVEL 
    situations requested, are once again file-compileable.  (reported
    by Sascha Wilde)

[It] fell dead-born from the press, without reaching such distinction
as even to excite a murmur among the zealots. But being naturally of
a cheerful and sanguine temper, I soon recovered from the blow and 
prosecuted with great ardour my studies in the country.
  -- David Hume, re. reaction to _A Treatise of Human Nature_

I have just made one change in policy on sbcl-devel and sbcl-help:
posts from nonsubscribers are now disabled in hopes of reducing spam.

I also noticed an option for another change that I might make: perhaps
the size cutoff for postings should be more than 40kB? My impression
(as the person who belatedly approves them) is that 57kB posts on
sbcl-devel are usually appropriate things like patches. I am inclined
to bump the limit for sbcl-devel up to 80kB-100kB or so, and to bump
the limit for sbcl-commits up to something like 200kB. However, I'd
like to give subscribers a chance to comment on it first: if you like
to read sbcl-devel through your slow ham radio link from your sailboat
off the coast of Antarctica and don't want it to clog up your
connection, now's a good time to let me know.

People who send spam to Emperor Cartagia... vanish! _They say_ that there's 
a room where he has their heads, lined up in a row on a desk... _They say_ 
that late at night, he goes there, and talks to them... _they say_ he asks 
them, 'Now tell me again, how _do_ you make money fast?' -- Matthew B. Kennel
