 changes relative to sbcl-1.0.56:
+  * RANDOM enhancements and bug fixes:
+    ** bug fix: the range and distribution of random integers could be
+       catastrophically wrong when the compiler derived the type of its
+       argument as a disjoint set of small integers.
+    ** bug fix: the distribution of random integers is now completely
+       uniform even when the specified limit is not a power of two.
+       (Previously some values could be about 0.1 % more probable than
+       others in the worst case.)
+    ** RANDOM on large integer arguments is generally faster and conses
+       less than before; this is visible for fixnums above a length of
+       about 24 bits, but extremely so for bignums: the old implementation
+       used time and space quadratical in the size of the argument there,
+       the new one is linear.
+  * enhancement: redesigned protocol for quitting SBCL. SB-EXT:EXIT is the new
+    main entry point, SB-EXT:QUIT is deprecated.
+  * enhancement: additions to the SB-THREAD API: RETURN-FROM-THREAD,
+    ABORT-THREAD, MAIN-THREAD-P, and MAIN-THREAD.
+  * enhancement: FASL loading no longer grabs the world-lock.
   * enhancement: GENCGC reclaims space more aggressively when objects being
     allocated are a large fraction of the total available heap space.
     (lp#936304)
   * enhancement: backtraces show the correct number of arguments for frames
     called with too many arguments.
+  * enhancement: support for abort(3), exit(3), and _exit(2) has been added to
+    SB-POSIX.
+  * enhancement: ASDF has been updated 2.21.
   * optimization: fewer uses of full calls to signed modular functions.
     (lp#903821)
   * optimization: typechecking alien values is typically 5 x faster.
   * optimization: FDEFINITION, SYMBOL-FUNCTION, MACRO-FUNCTION, and FBOUNDP
     are 20% faster.
+  * bug fix: file compilation performance issues when dumping subtypes
+    of CHARACTER (lp#994487)
   * bug fix: fixed disassembly of some SSE instructions on x86-64.
   * bug fix: SB-SIMPLE-STREAMS signals an error for bogus :CLASS arguments in
     OPEN. (lp#969352, thanks to Kambiz Darabi)
