+changes in sbcl-1.0.29.54.rc1 relative to sbcl-1.0.29:
+  * minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and
+    SB-THREAD:INTERRUPT-THREAD-ERROR-THREAD have been deprecated in favor
+    of SB-THREAD:THREAD-ERROR-THREAD.
+  * new contrib module: SB-QUEUE provides thread-safe lockless FIFO queues.
+  * new feature: docstrings for local and anonymous functions are no longer
+    discarded. (thanks to Leslie Polzer)
+  * new feature: SB-THREAD:SYMBOL-VALUE-IN-THREAD provides access to symbol
+    values in other threads.
+  * new feature: SB-INTROSPECT:ALLOCATION-INFORMATION provides information
+    about object allocation.
+  * optimization: division of a real float by a complex float is implemented
+    with a specialised code sequence.
+  * optimization: MAKE-INSTANCE with non-constant class-argument but constant
+    keywords is an order of magnitude faster.
+  * optimization: MAKE-INSTANCE with constant keyword arguments is x2-4 faster
+    in the presence of :AROUND or non-standard primary INITIALIZE-INSTANCE
+    methods, and similarly for non-standard metaclass classes as long as there
+    are no methods additional on MAKE-INSTANCE.
   * optimization: more efficient type-checks for FIXNUMs when the value
     is known to be a signed word on x86 and x86-64.
+  * optimization: compiler now optimizes (EXPT -1 INTEGER), (EXPT -1.0 INTEGER),
+    and (EXPT -1.0d0 INTEGER) into an ODDP test. (thanks to Stas Boukarev and
+    Paul Khuong)
+  * optimization: compiler is smarter about delegating argument type checks to
+    callees.
+  * optimization: several character functions are now compiled somewhat more
+    efficiently. (reported by Lynn Quam)
+  * optimization: the compiler now derives simple types for LOAD-VALUE-FORMs.
+  * improvement: less unsafe constant folding in floating point arithmetic,
+    especially for mixed complex/real -float operations.
+  * optimization: constant double and single floats are stored in native
+    unboxed format on x86[-64].
+  * optimization: smarter code for arithmetic operations with constant floats,
+    complex floats, or integers on x86[-64].
+  * optimization: smarter code for conjugate/multiplication of float complexes
+    and abs/negate of floats on x86-64.
+  * optimization: more efficient complex float and real float operations on
+    x86-64.
+  * improvement: complex float division is slightly more stable.
+  * improvement: DESCRIBE output has been reworked to be easier to read and
+    contains more pertinent information.
   * improvement: failure to provide requested stack allocation compiler notes
     provided in all cases (requested stack allocation not happening without a
     note being issued is now considered a bug.)
+  * bug fix: SB-POSIX exports the documented types and functions
+    FILE-DESCRIPTOR and FILENAME, and also the corresponding -DESCRIPTOR
+    types. (reported by "abhi")
   * bug fix: on 64 bit platforms FILL worked incorrectly on arrays with
     upgraded element type (COMPLEX SINGLE-FLOAT), regression from 1.0.28.55.
     (thanks to Paul Khuong)

   * bug fix: better error signalling when calls to functions seeking elements
     from lists (eg. ADJOIN) are compiled with both :TEST and :TEST-NOT.
     (reported by Tobias Rittweiler)
-  * bug fix: regression in DIRECTORY from 1.0.28.61, pattern matching of
-    directory components now works again.
+  * bug fix: regressions in DIRECTORY from 1.0.28.61: pattern matching of
+    directory components now works as it used to. (various prolems reported by
+    Michael Becker, Gabriel Dos Reis, Cyrus Harmon, and Harald Hanche-Olsen)
+  * bug fix: :PTY option in RUN-PROGRAM was broken with stream arguments.
+    (reported by Elliot Slaughter, thanks to Stas Boukarev)
+  * bug fix: bogus undefined variable warnings from fopcompiled references to
+    global variables. (thanks to Lars Rune Nøstdal)
+  * bug fix: foreign function names should now appear in backtraces on
+    FC6 as well. (reported by Tomasz Skutnik and Tobias Rautenkranz)
+  * bug fix: SETF compiler macro documentation strings are not discarded
+    anymore.
+  * bug fix: GENTEMP is now unaffected by pretty printer dispatch table.
+    (thanks to Alex Plotnick)
+  * bug fix: SLEEP accepts large integer arguments, truncating them to
+    SIGNED-WORD on the assumption that sleeping for 68 years is sufficient
+    for anyone. (reported by Leslie Polzer, thanks to Stas Boukarev)
+  * bug fix: compiler notes for expensive slot type checks could be emitted
+    at runtime MAKE-INSTANCE calls. (reported by Samium Gromoff)
