+changes relative to sbcl-1.0.53:
+  * minor incompatible changes:
+    ** RENAME-FILE on a symbolic links used to rename the linked-to file instead
+       of the link.
+    ** DELETE-DIRECTORY on symbolic link to a directory used to delete the
+       directory, but now signal an error instead. Use TRUENAME to resolve
+       the pathname if you wish to delete the linked directory, and DELETE-FILE
+       if you wish to delete the
+    ** The internal SB-THREAD::SPINLOCK API has been deprecated, and using
+       symbols associated with it will trigger a compile-time warning.
+  * thread-related enhancements:
+    (This work has been funded by the SBCL Threading 2011 IndieGoGo campaign.
+     Many thanks to generous donors!)
+    ** Threading is now more reliable on non-Linux platforms. We still
+       don't consider threads on non-Linux platforms good enough to
+       enable them by default, but they're in a clearly better shape now.
+    ** Deadlines supported now on all platforms.
+    ** All blocking functions in the threading API now have a :TIMEOUT
+       argument.
+    ** Semaphore notification objects have been added to SB-THREAD.
+    ** SB-CONCURRENCY contrib now includes Allegro-style GATE objects.
+    ** SB-EXT:COMPARE-AND-SWAP has been extended to support SLOT-VALUE,
+       STANDARD-INSTANCE-ACCESS, and FUNCALLABLE-STANDARD-INSTANCE-ACCESS.
+    ** Users can now defined new places usable with SB-EXT:COMPARE-AND-SWAP
+       using an API anologous to defining new SETFable places.
+  * enhancement: debug-names of anonymous and local function are more
+    descriptive. Affects backtraces and SB-SPROF results. (lp#805100)
+  * enhancement: on GENCGC systems nursery and generation sizes now default to
+    5% of dynamic-space size.
+  * enhancement: on CHENEYGC targets, SB-KERNEL:MAKE-LISP-OBJ now does
+    the same validation of pointer objects as GENCGC does, instead of a
+    comparatively weak bounds-check against the heap spaces.
+  * enhancement: on win32, ABS of complex floats guards better against
+    overflows. (lp#888410)
+  * enhancement: RUN-PROGRAM now distinguishes exec() failing from child
+    process exiting with code 1. (lp#676987)
+  * enhancement: convenience function SET-SBCL-SOURCE-LOCATION for informing
+    the system where on the filesystem the SBCL sources themselves are
+    located.  (Thanks to Zach Beane)
+  * bug fix: on 64-bit targets, atomic-incf/aref does index computation
+    correctly, even on wide-fixnum builds. (lp#887220)
+  * bug fix: (directory "foo/*/*.*") did not follow symlinks in foo/ that
+    resolved to directories.
+  * bug fix: SB-KERNEL:MAKE-LISP-OBJ on GENCGC no longer categorically
+    refuses to create SIMPLE-FUN objects.
+  * bug fix: type mismatch when assigning to lexical variables no longer
+    result in fasl-dumping internal type objects. (lp#890750)
+  * bug fix: type mismatch on (setf aref) and function return values no
+    longer result in fasl-dumping internal type objects.
+  * bug fix: SB-BSD-SOCKETS issues
+    ** GET-PROTOCOL-BY-NAME had a significant memory leak.
+    ** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS small amounts of memory on
+       systems with getaddrinfo().
+    ** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS weren't thread or interrupt
+       safe outside systems with getaddrinfo().
+  * bug fix: on 64-bit systems setting the nursery size above 4Gb now works.
+    (lp#870868)
+
+changes in sbcl-1.0.53 relative to sbcl-1.0.52:
   * enhancement: on 64-bit targets, in src/compiler/generic/early-vm.lisp,
     the parameter n-fixnum-tag-bits may now vary from 1 (fixnum =
     (signed-byte 63)) to 3 (fixnum = (signed-byte 61)) at build-time.
+  * enhancement: SB-EXT:WAIT-FOR allows waiting for arbitrary events.
   * minor(?) incompatible(?) change: The default fixnum width on 64-bit
     targets is now 63 bits (up from 61).
+  * enhancement: DESCRIBE now reports a lambda-list and source location
+    for complext setf-expanders.
+  * bug fix: PUSH, PUSHNEW, POP, REMF, INCF, DECF, DEFINE-MODIFY-MACRO,
+    GETF, LOGBITP, LDB, and MASK-FIELD now arrange for non-primary values
+    of multiple-valued places to be set to NIL, instead of signalling an
+    error (per a careful reading of CLHS 5.1.2.3).
+  * bug fix: floating-point traps now work on darwin/x86 and /x86-64.
+  * bug fix: repair crash in x86oid darwin signal handling emulation
+    when built with certain compilers.
+  * bug fix: SB-ROTATE-BYTE misrotated to the right when using constant
+    rotation arguments on x86-64. (lp#882151)
+  * bug fix: low-level control flow optimisations could result in bogus
+    code in functions with tail and non-tail calls to local functions on
+    x86oids. (lp#883500)
+  * bug fix: on SPARC/:sb-unicode, avoid crashing the assembler by trying
+    to emit literal characters > (code-char 4095), for comparisons with
+    constant characters.
+  * bug fix: ROOM reported only the low 32 bits of dynamic space usage
+    on 64 bit platforms. (lp#881445)
+  * bug fix: DELETE-FILE did not MERGE-PATHNAMES, making it possible to
+    delete the wrong file when using relative pathnames. (lp#882877)
+  * bug fix: optimized SEARCH of vectors-on-vectors mishandled zero-length
+    sequences and :KEY NIL.
 
 changes in sbcl-1.0.52 relative to sbcl-1.0.51:
   * enhancement: ASDF has been updated to version 2.017.
