(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. + +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.
