- Update to version 1.1.18
  * Optimization
    + COERCE is now more effecient for more cases when
      the type is known at compile-time.  (lp#1309815)
  * Bug fix
    + correctly inherit condition initforms. (lp#1300904)
    + properly pprint literal functions inside nested lists.
     (lp#1300716)
    + more-correctly handle array-type unity (broken for
      ages, causing compilation problems since 1.1.13.x due to
      smarter TYPEP type propagation reported by jasom in #lisp). 

- Use clisp for those distros and archs where sbcl is not available 
  yet

- Update to version 1.1.16
  * Enhancement
    +  SB-EXT:DEFINE-LOAD-TIME-GLOBAL. (lp#1253688)
    +  Loading fasls with symbols from an undefined package includes
      the name of the symbol in the error message.
  * Bug fix
    + problems when redefining classes and doing TYPEP on classes
      concurrently. (lp#1272742)
    + fixes to the x86-64 XCHG instruction:
      - it was misencoded when used with RAX, R8-R15 registers.
       (reported by  Eric Marsden)
      - it was misencoded when used to exchange EAX with itself.
      - the disassembler wrongly printed XCHG RAX, R8 and the
        corresponding 32- and 16-bit variations as NOP.

- Update to version 1.1.15
  * New feature:
    the iterative spilling/coloring register allocator developed
    by Alexandra Barchunova during Google Summer of Code 2013 is
    now merged in. By default, it only activates for functions that
    optimize with (speed 3) and (> speed compilation-speed), but
    setting sb-regalloc:*register-allocation-method* to :iterative
    forces its execution. The previous behaviour can be obtained by
    instead setting that variable to :greedy.
  * Optimization:
    + make-array with known element-type and unknown dimensions is
      much faster.
    + make-array with unknown element-type is faster as well.
     (lp#1004501)
  * Enhancement:
    + reduced conservativism on GENCGC platforms: conservative roots
       must be valid-looking tagged pointers or point within a code
       object, not merely point to within the allocated part of a
       page, in order to pin a page.
    + support for "Mac Roman" external format.
    + encapsulation of named generic functions now happens without
      altering the identity of the function bound to the name.
  * Bug fix:
    + modular arithmetic optimizations do not stumble on dead branches
      with bad constants. (reported by Douglas Katzman)
    + CLISP can be used again as a cross-compilation host.
      (Thanks to Vasily Postnicov, lp#1261451)
    + run-program crashed with :directory nil. (lp#1265077)

- Update to version 1.1.14
  * Optimization:
    + complicated TYPEP tests are less opaque to the
      type propagation pass. (lp#1229340)
    + [N]BUTLAST perform a single pass over the list.
      (lp#1245697)
    + EQUALP on structures with raw slots (double-float/complex)
      no longer conses and is faster.
    + RESTART-CASE expands to more compact code.
      Thanks to Jan Moringen. (lp#1249055)
  * Enhancement:
    + Top-level defmethod without defgeneric no longer
      causes  undefined-function warnings in subsequent forms.
      (lp#503095)
    + run-sbcl.sh is usefully handled by rlwrap.  Thanks
      to William Cushing. (lp#1249183)
    + new function SB-EXT:ASSERT-VERSION->= accepts a version
      specification (multiple integer arguments) and signals a
      continuable error if the current SBCL version is lower (older)
      than the specification. (lp#674372)
    + better ARRAY-RANK result derivation. (lp#1252108)
  * Bug fix:
    + EQUALP now compares correctly structures with raw slots larger
      than a single word.
    + OPEN reports a more meaningful error when an existing file is
      opened for output with :if-exists :new-version.Thanks to
      Philip Munksgaard. (lp#455381)
    + DEFSTRUCTs with NIL as a slot name no longer cause strange
      CLOS-related errors.  (lp#633911)

- Update to version 1.1.13
  * Optimization:
    + better distribution of SXHASH over small conses of related
      values.  (lp#309443)
    + other improvements to SXHASH:
      - use the whole of the positive-fixnum range for SXHASH of
        fixnums
  * Enhancement:
    + The error message when calling an undefined alien function
      includes the name of the function on x86-64.
    + sb-ext:run-program now supports :environment on Windows.
    + ASDF is no longer required to load contribs at runtime.
     (lp#1132254)

    + FIND-RESTART and COMPUTE-RESTARTS handle huge restart
      clusters better in some cases
    + SOME/ANY/other quantification higher-order functions no
      longer cons. (lp#1070635)
  * Bug fix:
    + forward references to classes in fasls can now be loaded.
      (lp#746132)
    + don't warn on a interpreted->compiled function redefinition
      from the same location.  (patch by Douglas Katzman, lp#1042405)
    + Create vectors of proper internal length when reading literal
      vectors from FASLs. (Reported by Jan Moringen)
    + COMPILE can now succefully compile setf functions.
     (Reported by Douglas Katzman)
    + run-program performs more correct escaping of arguments on
      Windows. (lp#1239242)

    + Add sb-bsd-sockets:socket-shutdown, for calling
      shutdown(3). lp#1207483
    + document extensible sequences.  lp#994528
  * Optimization:
    + EQUAL and EQUALP transforms are smarter.  lp#1220084
    + CHAR-EQUAL is faster for constant and base-char arguments.
  * Bug fix:
    + probe-file now can access symlinks to pipes and sockets in
     /proc/pid/fd on Linux. (reported by Eric Schulte)
    + SBCL can now be built on Solaris x86-64.
    + Floating point exceptions do not persist on Solaris anymore.
    + (setf . a) is pprinted correctly
    + handle compiler-error in LOAD when it's not run from inside EVAL.
      lp#1219601

    + space allocation of result bignums in SB-GMP is more accurate.
      lp#1206191

      clobbers FILE-NAMESTRING.  lp#884603
    + class definitions with CPLs inconsistent with their  metaclasses

- Update to version 1.1.11
  * Enhancement:
    + support building the manual under texinfo version 5 lp#1189146
  * Bug fix:
    + undefined function errors are now properly reported on
      PPC and MIPS.  (regression since 1.1.9)
    + (funcall (function X junk)) didn't causes an error
      when X had a  compiler macro.
    + signal a warning when defining a setf-function when a
       setf-expander is already present.
    + improved threading on PPC.  
    + Streams were flushed even when there was one byte

- Update to version 1.1.10
  * Enhancement:
    + ASDF has been updated to 3.0.2.
  * Optimization:
    + stack frames are packed more efficiently on
      x86oids, which  ought to reduce the frequency of Methuselahn
      conservative references (it certainly helps with gc.impure.lisp
      / BUG-936304 on x86).
    + on x86 and x86-64, integer negation forms like
     (- * x) are now recognized in modular arithmetic contexts, and
     compile to native negate, rather than going through bignums only
     to keep the low bits.
  * Bug fix
    + Compiling potential modularic arithmetic forms does
      not cause type errors when some integer types lack lower or upper
      bounds.  (lp#1199127)
    + Non-trivial modular arithmetic forms are always cut to
      the right  bitwidth before being used in a non-modular context.
      (lp#1199428)
    + Multiple catch/unwind blocks in a single function are now
      allocated in the right stack order on win32. (lp#1072739)

- Update to version 1.1.9
  * New feature:
    + the contrib SB-GMP links with libgmp at runtime to speed up
    arithmetic on bignums and ratios. (contributed by Stephan
    Frank)
  * Enhancement:
    + disassemble now annotates some previously
      missing static functions, like LENGTH.
    + SB-EXT:PRINT-SYMBOL-WITH-PREFIX can be used within ~// to
      print a symbol with a package prefix.
    + The debugger and backtracing are more robust against buggy
      PRINT-OBJECT methods.
  * Optimization:
    + calls to static functions on x86-64 use less instructions.
    + compute encode-universal-time at compile time when possible.
    + when referencing internal functions as #'x, don't go through
      an indirect fdefn structure.
    + SLEEP doesn't cons on non-immediate floats and on ratios.
    + (mod fixnum) type-checks are performed using one unsigned
      comparison, instead of two.
    + enable more modular arithmetic transforms in the presence of
     conditionals.
    + bitwise OR forms can now trigger modular arithmetic as well,
      when the result is known to be negative.
    + recognize more cases of useless LOGAND/LOGIOR with constants.
    + comparisons between rationals and constant floats or between
      integers and constant ratios are now converted to rationals/integers
      at compile time.
    + Smaller and faster DOUBLE-FLOAT-LOW-BITS on x86-64.
