changes in sbcl-2.3.1 relative to sbcl-2.3.0:
  * sb-graph has been removed. To visualize IR1 in sbcl, it is recommended to
    use the function IR1-TO-DOT (which only survives the final tree shake if
    the feature :sb-devel is enabled at build time).
  * platform support:
    ** implement some peephole optimizations on arm64;
    ** support float traps on arm64;
  * bug fix: package-manipulation operations within fasls work as expected in
    the absence of explicit block compilation requests.  (lp#2000004, reported
    by Shubhamkar Ayare)
  * bug fix: incorrect type simplification of certain CONS types.
    (lp#1999352, reported by Paul Dietz)
  * bug fix: method combination group selection interprets the symbol * as
    a wildcard element within proper qualifier-pattern lists.  (reported by
    Maciej Katafiasz and by Daniel Kochmański)
  * bug fix: &WHOLE can be used without error in define-method-combination
    arguments lambda lists.  (reported by Daniel Kochmański)
  * bug fix: bogus debug variables generated for closure variables whose value
    cell had not yet been allocated could cause segfaults and gc crashes
    (reported by _death on #sbcl)
  * bug fix: handling of float NaNs in two-arg numeric comparison functions is
    more consistent with the required semantics in IEEE 754 when comparing
    with rationals.
  * bug fix: ensure that the hide-packages test passes even when the system
    retains internal cross-reference metadata.  (lp#2002896, reported by 3b)
  * bug fix: don't trip an internal assertion in weak hash tables with
    finalizers.  (lp#1998064)
  * optimization: load-time only code is no longer retained at runtime when
    functions close over top level bindings.
  * optimization: GO and RETURN-FROM now elide out-of-extent tag checks when
    the compiler can prove it's safe even on high safety.
  * optimization: addition of a fixnum to a bignum generates less garbage.
  * optimization: in many cases, type inference and code generation is
    improved for and around numerical comparison functions.
