sbcl-1.4.8 released

Dear all,

I have released sbcl-1.4.8, with source and a binary available on
SourceForge.  The major changes in this release are detailed below; it
is perhaps also worth announcing that developers have begun thinking of
removing from the release various less-well-supported platforms (HPPA,
Alpha, IRIX) -- if this affects anyone here, please say so!

Best wishes,

Christophe

changes in sbcl-1.4.8 relative to sbcl-1.4.7:
  * bug fix: redefinition of method combinations now does the expected thing;
    generic functions using that method combination have their effective
    methods lazily recomputed according to the new definition of the method
    combination.  (Reported by Didier Verna at ELS 2018)
  * bug fix: :arguments argument to the long form of DEFINE-METHOD-COMBINATION
    is now implemented more correctly, supporting suppliedp variables and
    &optional defaults.  (Reported by Bruno Haible, lp#309084)
