the byte fasl file version is now equal to the ordinary
fasl file version.
+changes in sbcl-0.7.0 relative to sbcl-0.6.13:
+* incompatible change: The default fasl file extension has changed
+ to ".fasl", for all architectures. (No longer ".x86f" and ".axpf".)
+* There are new compiler optimizations for various functions: FIND,
+ POSITION, FIND-IF, POSITION-IF, FILL, COERCE, TRUNCATE, FLOOR, and
+ CEILING. Mostly these should be transparent, but there's one
+ potentially-annoying problem (bug 117): when the compiler inline
+ expands the FIND/POSITION family of functions and does type
+ analysis on the result, it can find control paths which have
+ type mismatches, and when it can't prove that they're not taken,
+ it will issue WARNINGs about the type mismatches. It's not clear
+ how to make the compiler smart enough to fix this in general, but
+ a workaround is given in the entry for 117 in the BUGS file.
+* The doc/cmucl/ directory, containing old CMU CL documentation,
+ is no longer part of the base system. The files which used to
+ be in the doc/cmucl/ directory are now available as
+ <ftp://sbcl.sourceforge.net/pub/sbcl/cmucl-docs.tar.bz2>.
+* The default value of *BYTES-CONSED-BETWEEN-GCS* has been
+ doubled, to 4 million. (If your application spends a lot of time
+ GCing and you have a lot of RAM, you might want to experiment with
+ increasing it even more.)
+?? The system's handling of top-level forms and EVAL-WHEN is now
+ more ANSI-compliant, fixing bugs
+ ?? IR1-3 and
+ ?? IR1-3a.
+ It's also done by much newer code, so there might be some new bugs,
+ but hopefully if so they'll be less fundamental and more fixable.
+* PPRINT-LOGICAL-BLOCK now copies the *PRINT-LINES* value on entry
+ and uses that copy, rather than the current dynamic value, when
+ it's trying to decide whether to truncate output . Thus e.g.
+ (let ((*print-lines* 50))
+ (pprint-logical-block (stream nil)
+ (dotimes (i 10)
+ (let ((*print-lines* 8))
+ (print (aref possiblybigthings i) stream)))))
+ should truncate the logical block only at 50 lines, instead of
+ often truncating it at 8 lines.
+* :SB-CONSTRAIN-FLOAT-TYPE, :SB-PROPAGATE-FLOAT-TYPE, and
+ :SB-PROPAGATE-FUN-TYPE are no longer considered to be optional
+ features. Instead, the code that they used to control is always
+ built into the system.
+* lots of tidying up internally: renaming things so that names are
+ more systematic and consistent, converting C macros to inline
+ functions, systematizing indentation
+* The fasl file version number changed again, for any number of
+ good reasons.
+
planned incompatible changes in 0.7.x:
* The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc.
as you get deeper into recursive calls to the debugger command loop,
instead of the old "5]", "5]]", "5]]]" sequence. (I was motivated
to do this when squabbles between ILISP and SBCL left me
very deeply nested in the debugger.)
-* The fasl file extension may change, perhaps to ".fasl".
* The default output representation for unprintable ASCII characters
which, unlike e.g. #\Newline, don't have names defined in the
ANSI Common Lisp standard, may change to their ASCII symbolic
