sbcl-1.0.10 has been released.

It is available in SourceForge CVS and on the File Releases pages.

>From the NEWS file in the distribution:
changes in sbcl-1.0.10 relative to sbcl-1.0.9:
  * minor incompatible change: the MSI installer on Windows no longer
    associates .lisp and .fasl files with the installed SBCL.
  * minor incompatible change: :UNIX is no longer present in *FEATURES*
    on Windows. (thanks to Luis Oliviera)
  * new feature: SB-CLTL2 contrib module now implements
    FUNCTION-INFORMATION. (thanks to Larry D'Anna)
  * optimization: scavenging weak pointers is now more efficient,
    requiring O(1) instead of O(N) per weak pointer to identify
    scanvenged vs. unscavenged pointers. (thanks to Paul Khuong)
  * optimization: typechecking (SETF SLOT-VALUE) is now ~5x faster in
    method bodies using constant slot-names when the first argument is
    a specializer parameter for the method.
  * optimization: SLOT-VALUE &co are now ~50% faster for variable slot
    names, when the class of the instance is a direct instance
    STANDARD-CLASS or FUNCALLABLE-STANDARD-CLASS (making them only 3x
    as slow as the constant slot-name case.)
  * optimization: member type construction is now O(N) instead
    of O(N^2).
  * optimization: UNION and NUNION are now O(N+M) for large
    inputs as long as the :TEST function is one of EQ, EQL, EQUAL, or
    EQUALP.
  * enhancement: DEFINE-MODIFY-MACRO lambda-list information is
    now more readable in environments like Slime which display it.
    (thanks to Tobias C. Rittweiler)  
  * bug fix: SB-EXT:COMPARE-AND-SWAP was non-atomic unless the compiler
    was able to infer the correct argument type for the object on which
