+changes in sbcl-1.0.13 relative to sbcl-1.0.12:
+  * minor incompatible change: RUN-PROGRAM now uses execvp(3) to find
+    an executable in the search path, and does so in the child
+    process's PATH.  The function FIND-EXECUTABLE-IN-SEARCH-PATH has
+    been removed; it can be found in the CVS history, for somebody who
+    needs that search behavior (see the manual).
+  * minor incompatible change: compiler policy re. weakening type
+    checks has changed: now type checks are weakened on if SAFETY < 2
+    and SAFETY < SPEED.
+  * SB-EXT:NATIVE-NAMESTRING takes a new keyword AS-FILE, forcing
+    unparsing of directory pathnames as files. Analogously,
+    SB-EXT:PARSE-NATIVE-NAMESTRING takes an AS-DIRECTORY, forcing a
+    filename to parse into a directory pathname.
+  * enhancement: implicit generic function creation now signals a
+    specific style-warning IMPLICIT-GENERIC-FUNCTION-WARNING, which
+    users can bind handlers for and muffle around calls to LOAD.
+  * enhancement: RUN-PROGRAM allows unicode arguments and environments
+    to be used (using the default stream external format), and allows
+    non-simple strings to be used. (thanks to Harald Hanche-Olsen)
+  * optimization: COPY-SEQ, FILL, and SUBSEQ are 30-80% faster for
+    strings and vectors whose element-type or simplicity is not fully
+    known at compile-time.
+  * optimization: STRING-TRIM and related functions no longer allocate
+    a new string when no trimming needs to be performed. These functions
+    are also faster than before when the input string has been declared
+    as a simple-string.
+  * optimization: READ-SEQUENCE on simple-strings is up to 80% faster.
+  * optimization: READ-LINE is significantly faster for files containing
+    long lines.
+  * optimization: non-open coded uses of character comparison operators
+    (e.g. char=) no longer cons when called with more than one parameter
+    on platforms supporting dynamic-extent allocation.
+  * bug fix: READ-SEQUENCE on composite stream wrapping a Gray stream
+    with STREAM-ELEMENT-TYPE (UNSIGNED-BYTE 8) signalled an error.
+  * bug fix: COPY-SEQ on lists did not signal a type-error on improper
+    lists in safe code.
+  * bug fix: some sequence functions elided bounds checking when
+    SPEED > SAFETY.
+  * bug fix: too liberal weakening of union-type checks when SPEED >
+    SAFETY.
+  * bug fix: more bogus fixnum declarations in ROOM implementation
+    have been fixed.
+
 changes in sbcl-1.0.12 relative to sbcl-1.0.11:
   * new feature: MAKE-HASH-TABLE now experimentally accepts a
     :SYNCHRONIZED argument, which makes the hash-table safe for
     concurrent accesses (but not iteration.) See also:
     SB-EXT:WITH-LOCKED-HASH-TABLE, and
     SB-EXT:HASH-TABLE-SYNCHRONIZED-P.
+  * optimization: CONCATENATE on strings is an order of magnitue faster
+    in code compiled with (> SPEED SPACE).
+  * optimization: SUBSEQ is ~50% faster on lists.
+  * bug fix: bug 417 fixed -- source location reporting is now more robust.
+  * bug fix: SUBSEQ on a list will now correctly signal an error if if
+    END is smaller then START.
+  * bug fix: SB-PROFILE will no longer report extra consing for nested
+    calls to profiled functions.
+  * bug fix: ROOM implementation had bogus fixnum declarations which
+    could cause type-errors when calling ROOM on large images.
+  * bug fix: if file compilation is aborted, the partial fasl is now
+    deleted, and COMPILE-FILE returns NIL as the primary value.
   * bug fix: number of thread safety issues relating to SBCL's internal
     hash-table usage have been fixed.
   * bug fix: SB-SYS:WITH-PINNED-OBJECTS could cause garbage values to
