(The ANSI definition of COMPILE-FILE-PATHNAME + seems to expect a single default extension for all compiled code, + and there's no compelling reason to try to stretch the standard + to allow two different extensions.) Instead, byte-compiled files + default to the same extension as native-compiled files. +* Fasl file format version numbers have increased again, because + a rearrangement of internal implementation packages made some + dumped symbols in old fasl files unreadable in new cores. +* DECLARE/DECLAIM/PROCLAIM logic is more nearly ANSI in general, with + many fewer weird special cases. +* Bug #17 (differing COMPILE-FILE behavior between logical and + physical pathnames) has been fixed, and some related misbehavior too, + thanks to a patch from Martin Atzmueller. +* Bug #30 (reader problems) is gone, thanks to a CMU CL patch + by Tim Moore, ported to SBCL by Martin Atzmueller. +* Martin Atzmueller fixed several filesystem-related problems, + including bug #36, in part by porting CMU CL patches, which were + written in part by Paul Werkowski. +* More compiler warnings in src/runtime/ are gone, thanks to + more patches from Martin Atzmueller. +* Martin Atzmueller pointed out that bug 37 was fixed by his patches + some time ago. + +changes in sbcl-0.6.11 relative to sbcl-0.6.10: +* Martin Atzmueller pointed out that bugs #9 and #25 are gone in + current SBCL. +* bug 34 fixed by Martin Atzmueller: dumping/loading instances works + better +* fixed bug 40: TYPEP, SUBTYPEP, UPGRADED-ARRAY-ELEMENT-TYPE, + and UPGRADED-COMPLEX-PART-TYPE now work better with of compound + types built from undefined types, e.g. '(VECTOR SOME-UNDEF-TYPE). +* DESCRIBE now works on structure objects again. +* Most function call argument type mismatches are now handled as + STYLE-WARNINGs instead of full WARNINGs, since the compiler doesn't + know whether the function will be redefined before the call is + executed. (The compiler could flag local calls with full WARNINGs, + as per the ANSI spec "3.2.2.3 Semantic Constraints", but right now + it doesn't keep track of enough information to know whether calls + are local in this sense.) +* Compiler output is now more verbose, with messages truncated + later than before. (There should be some supported way for users + to override the default verbosity, but I haven't decided how to + provide it yet, so this behavior is still controlled by the internal + SB-C::*COMPILER-ERROR-PRINT-FOO* variables in + src/compiler/ir1util.lisp.) +* Fasl file format version numbers have increased again, because + support for the Gray streams extension changes the layout of the + system's STREAM objects. +* The Gray subclassable streams extension now works, thanks to a + patch from Martin Atzmueller. +* The full LOAD-FOREIGN extension (not just the primitive + LOAD-FOREIGN-1) now works, thanks to a patch from Martin Atzmueller. +* The default behavior of RUN-PROGRAM has changed. Now, unlike CMU CL + but like most other programs, it defaults to copying the Unix + environment from the original process instead of starting the + new process in an empty environment. +* Extensions which manipulate the Unix environment now support + an :ENVIRONMENT keyword option which doesn't smash case or + do other bad things. The CMU-CL-style :ENV option is retained + for porting convenience. +* LOAD-FOREIGN (and LOAD-1-FOREIGN) now support logical pathnames, + as per Daniel Barlow's suggestion and Martin Atzmueller's patch + +changes in sbcl-0.6.12 relative to sbcl-0.6.11: +* incompatible change: The old SB-EXT:OPTIMIZE-INTERFACE declaration + is no longer recognized. I apologize for this, because it was + listed in SB-EXT as a supported extension, but I found that + its existing behavior was poorly specified, as well as incorrectly + specified, and it looked like too much of a mess to straighten it + out. I have enough on my hands trying to get ANSI stuff to work.. +* many patches ported from CMU CL by Martin Atzmueller, with + half a dozen bug fixes in pretty-printing and the debugger, and + half a dozen others elsewhere +* fixed bug 13: Floating point infinities are now supported again. +* fixed bug 45a: Various internal functions required to support + complex special functions have been merged from CMU CL sources. + (When I was first setting up SBCL, I misunderstood a compile-time + conditional #-OLD-SPECFUN, and so accidentally deleted them.) +* The --noprogrammer command line option is now supported. (Its + behavior is slightly different in detail from what the old man + page claimed it would do, but it's still appropriate under the + same circumstances that the man page talks about.) +* The :SB-PROPAGATE-FLOAT-TYPE and :SB-PROPAGATE-FUN-TYPE features + are now supported, and enabled by default. Thus, the compiler can + handle many floating point and complex operations much less + inefficiently. (Thus e.g. you can implement a complex FFT + without consing!) +* improved support for type intersection and union, fixing bug 12 + (e.g., now (SUBTYPEP 'KEYWORD 'SYMBOL)=>T,T) and some other + more obscure bugs as well +* various fixes to make the cross-compiler more portable to + ANSI-conforming-but-different cross-compilation hosts (notably + Lispworks for Windows, following bug reports from Arthur Lemmens) +* a new workaround to make the cross-compiler portable to CMU CL + again despite its non-ANSI EVAL-WHEN, thanks to Martin Atzmueller +* The compiler now detects type mismatches between DECLAIM FTYPE + and DEFUN better, thanks to patches from Martin Atzmueller. +* A bug in READ-SEQUENCE for CONCATENATED-STREAM has been fixed + thanks to Pierre Mai's CMU CL patch. +* new fasl file format version number (because of changes in byte + code opcodes and in internal representation of (OR ..) types) + 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 ILISP and SBCL got into arguments which left me deeply nested in the debugger.) +* When the profiling interface settles down, it might impact TRACE. + They both encapsulate functions, and it's not clear yet how + e.g. UNPROFILE will interact with TRACE and UNTRACE. (This shouldn't + matter, though, unless you are using profiling. If you never + profile anything, TRACE should continue to behave as before.) +* 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 + names: #\Nul, #\Soh, #\Stx, etc. +* INTERNAL-TIME-UNITS-PER-SECOND might increase, e.g. to 1000. +* MAYBE-INLINE will probably go away at some point, maybe 0.7.x, + maybe later, in favor of the ANSI-recommended idiom for making + a function optionally inline.
