 changes in sbcl-0.6.13 relative to sbcl-0.6.12:
-* a port to the Alpha CPU, thanks to Dan Barlow
+* a port to the Compaq/DEC Alpha CPU, thanks to Dan Barlow
 * Martin Atzmueller ported Tim Moore's marvellous CMU CL DISASSEMBLE
   patch, so that DISASSEMBLE output is much nicer.
-* better error handling in CLOS method combination, thanks to 
-  Martin Atzmueller and Pierre Mai
+* Pathnames and *DEFAULT-DIRECTORY-DEFAULTS* are much more
+  ANSI-compliant, thanks to various fixes and tests from Dan Barlow.
+  Also, at Dan Barlow's suggestion, TRUENAME on a dangling symbolic
+  link now returns the dangling link itself, and for similar
+  reasons, TRUENAME on a cyclic symbolic link returns the cyclic
+  link itself. (In these cases the old code signalled an error and
+  looped endlessly, respectively.) Thus, DIRECTORY now works even
+  in the presence of dangling and cyclic symbolic links.
+* Compiler trace output (the :TRACE-FILE option to COMPILE-FILE)
+  is now a supported extension again, since the consensus on
+  sbcl-devel was that it can be useful for ordinary development
+  work, not just for debugging SBCL itself.
+* The default for SB-EXT:*DERIVE-FUNCTION-TYPES* has changed to
+  NIL, i.e. ANSI behavior, i.e. the compiler now recognizes
+  that currently-defined functions might be redefined later with 
+  different return types. 
 * Hash tables can be printed readably, as inspired by CMU CL code
   of Eric Marsden and SBCL code of Martin Atzmueller.
-* a new slam.sh hack to shorten the edit/compile/debug cycle for
-  low-level changes to SBCL itself, and a new :SB-AFTER-XC-CORE
-  target feature to control the generation of the after-xc.core
-  file needed by slam.sh.
-* Compiler trace output (the :TRACE-FILE option to COMPILE-FILE)
-  is now a supported extension again, since the consensus is that
-  it can be useful for ordinary development work, not just for
-  debugging SBCL itself.
-?? more overflow fixes for >16Mbyte i/o buffers
+* better error handling in CLOS method combination, thanks to 
+  Martin Atzmueller porting Pierre Mai's CMU CL patches
+* more overflow fixes for >16Mbyte I/O buffers
+* A bug in READ has been fixed, so that now a single Ctrl-D
+  character suffices to cause end-of-file on character streams.
+  In particular, now you only need one Ctrl-D at the command
+  line (not two) to exit SBCL.
+* fixed bug 26: ARRAY-DISPLACEMENT now returns (VALUES NIL 0) for 
+  undisplaced arrays.
+* fixed bug 107 (reported as a CMU CL bug by Erik Naggum on 
+  comp.lang.lisp 2001-06-11): (WRITE #*101 :RADIX T :BASE 36) now
+  does the right thing.
+* The implementation of some type tests, especially for CONDITION
+  types, is now tidier and maybe faster, due to CMU CL code
+  originally by Douglas Crosher, ported by Martin Atzmueller.
+* Some math functions have been fixed, and there are new
+  optimizers for deriving the types of COERCE and ARRAY-ELEMENT-TYPE,
+  thanks to Raymond Toy's work on CMU CL, ported by Martin Atzmueller.
+* A bug in COPY-READTABLE was fixed. (Joao Cachopo's patch to CMU
+  CL, ported to SBCL by Martin Atzmueller)
+* DESCRIBE now gives more information in some cases. (Pierre Mai's
+  patch to CMU CL, ported to SBCL by Martin Atzmueller)
+* The code in the SB-PROFILE package has been substantially 
+  improved, although it's still unstable.
+* There's a new slam.sh hack to shorten the edit/compile/debug
+  cycle for low-level changes to SBCL itself, and a new
+  :SB-AFTER-XC-CORE target feature to control the generation of
+  the after-xc.core file needed by slam.sh.
 * minor incompatible change: The ENTRY-POINTS &KEY argument to 
   COMPILE-FILE is no longer supported, so that now every function
   gets an entry point, so that block compilation looks a little
   more like the plain vanilla ANSI section 3.2.2.3 scheme.
+* minor incompatible change: SB-EXT:GET-BYTES-CONSED now
+  returns the number of bytes consed since the system started,
+  rather than the number consed since the first time the function
+  was called. (The new definition parallels ANSI functions like
+  CL:GET-INTERNAL-RUN-TIME.)
+* minor incompatible change: The old CMU-CL-style DIRECTORY options,
+  i.e. :ALL, :FOLLOW-LINKS, and :CHECK-FOR-SUBDIRS, are no longer
+  supported. Now DIRECTORY always does the abstract Common-Lisp-y
+  thing, i.e. :ALL T :FOLLOW-LINKS T :CHECK-FOR-SUBDIRS T.
+* Fasl file version numbers are now independent of the target CPU,
+  since historically most system changes which required version
+  number changes have affected all CPUs equally. Similarly, 
+  the byte fasl file version is now equal to the ordinary
+  fasl file version.
 
 planned incompatible changes in 0.7.x:
 * The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc.
