changes in sbcl-2.4.10 relative to sbcl-2.4.9:
  * minor incompatible change: SB-POSIX::POSIX-FORK is no longer exported from
    SB-POSIX.  (The interface function, SB-POSIX:FORK, remains exported).
  * platform support:
    ** fix bugs in instruction encoding on RISC-V; (reported by Guillaume Le
       Vaillant)
    ** fix the location of the linkage-table comment in disassembly on 64-bit
       powerpc;
    ** elide allocation of empty number stack frames on arm64;
    ** fix crash on x86 platforms in compiling array dereferencing with
       computed offsets with negative intermediate results.  (lp#2084943)
  * enhancement: the error message from standard object slot typecheck
    functions in optimized constructors is clearer about the context of the
    failed type check.
  * enhancement: BREAK is no longer tail-called, even when in tail position.
  * enhancement: on arm64 and x86-64, specialized entry points for functions
    known to take or return fixed numbers of double floats are generated and
    can be automatically called without boxing intermediate floats.
  * bug fix: RUN-PROGRAM no longer leaks memory by referencing otherwise
    unreachable stream instances.
  * bug fix: exporting or unexporting symbols during package iteration no
    longer causes any symbol to be visited more times than expected.
  * bug fix: DISASSEMBLE preserves the comment marker across line-breaks for
    long function or segment names.  (lp#1889456, thanks to Fedorov Alexander)
  * bug fix: the compiler no longer loops infinitely trying to compile
    NOTINLINE calls to known functions with source transform definitions.
    (lp#2085451, reported by Fedorov Alexander)

  * optimization: EQUAL on lists should be faster.
  * optimization: fewer filesystem operations are performed when working out
    what to LOAD.

    associated operations.
  * optimization: strings are now hashed using FNV-1A, replacing Bob Jenkins'
    one-at-a-time hash.
  * optimization: fewer redundant validations of the sequence bounding indices
    in POSITION on strings.
  * optimization: many improvements to type derivation on the arguments to and
    results of standard functions
  * optimization: adding many (hundreds) methods to a generic function can be
    done faster.

changes in sbcl-2.4.7 relative to sbcl-2.4.6:
  * minor incompatible change: the compiler will emit optimization notes
    related to complex type checks only at high SPEED optimization settings.
  * minor incompatible change: the GET-FOREGROUND symbol is now exported from

    ** fix occasional saved core corruption on Win32.  (reported by Luís
       Borges de Oliveira)

changes in sbcl-2.4.6 relative to sbcl-2.4.5:
  * enhancement: name conflicts resulting from colliding symbols in IMPORT and

    colliding symbols.
