* 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 porting Pierre Mai's CMU CL patches
-* Pathnames are much more ANSI-compliant, thanks to various fixes
- and tests from Dan Barlow.
+* 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.

-* 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.
-* 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.
* 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
+* 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
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.
