+  * 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: more efficient type-checks for FIXNUMs when the value
+    is known to be a signed word on x86 and x86-64.
+  * optimization: (EXPT -1 INTEGER) is compiled into (IF (EVENP INTEGER) 1 -1).
+    (thanks to Stas Boukarev)
+  * 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.)
+  * optimization: compiler is smarter about delegating argument type checks to
+    callees.
+  * 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: looping around HANDLER-CASE could silently consume stack space
+    on each iteration. (reported by "foobar")
+  * 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: 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 obias Rautenkranz)
+  * bug fix: SETF compiler macro documentation strings are not discarded
+    anymore.
+  * bug fix: GENTEMP is now unaffected by pretty printer dispatch table.

   * minor incompatible change: under weak type checking policy integer
     types are weakened less aggressively.
   * minor incompatible change: SAVE-LISP-AND-DIE :TOPLEVEL function is now
     allowed to return, which causes SBCL to quit with exit status 0. Previously
     if the function returned with a small integer return value, that value
     was accidentally reused as the exit status.
+  * new feature: SB-EXT:DEFINE-HASH-TABLE-TEST allows defining new arguments
+    to MAKE-HASH-TABLE :TEST, and MAKE-HASH-TABLE has been extended with
+    :HASH-FUNCTION argument. Refer to user manual for details.
   * new feature: SB-EXT:DEFGLOBAL macro allows defining global non-special
     variables.
+  * new feature: SB-EXT:GET-TIME-OF-DAY provides access to seconds and
+    microseconds since the Unix epoch on all platforms.
   * new feature: SB-EXT:ALWAYS-BOUND proclamation inhibits MAKUNBOUND, and
     allows the compiler to safely elide boundedness checks for special
     variables.
