(There was a packaging bug in 0.7.0 which + left their definitions in SB-SYS::LOAD-FOREIGN and + SB-SYS::LOAD-1-FOREIGN. LOAD-FOREIGN and LOAD-1-FOREIGN are + vital for most things which interface to C-level interfaces, + like extensions working with sockets or databases or + Perl-compatible regexes or whatever, and the need to fix + this bug is the main reason that 0.7.1 was released so + soon after 0.7.0.) + ** DEFGENERIC is now choosier about the methods it redefines, so that + reLOADing a previously-LOADed file containing DEFGENERICs does + the right thing now. Thus, the Lispy edit/reLOAD-a-little/test + cycle now works as it should. (thanks to Alexey Dejneka) + ** Bug 106 (types (COMPLEX FOO) where FOO is an obscure type) was + fixed by Christophe Rhodes. (He actually submitted this patch + months ago, and I delayed until after 0.7.0.) + ** Bug 111 (internal compiler confusion about runtime checks on + FUNCTION types) was fixed by Alexey Dejneka. +* Some internal cleanups (getting rid of variables which aren't + needed now that the byte interpreter is gone) caused the fasl + file format number to change again. + +changes in sbcl-0.7.2 relative to sbcl-0.7.1: + * incompatible change: The compiler is now less aggressive about + tail call optimization, doing it only when (> SPACE DEBUG) or + (> SPEED DEBUG). (This is an incompatible change because there are + programs which relied on the old CMU-CL-style behavior to optimize + away their unbounded recursion which will now die of stack overflow.) + * minor incompatible change: The default BYTES-CONSED-BETWEEN-GCS + for non-GENCGC systems has been increased to 20M (since that + seems much closer to the likely performance optimum for modern + systems than the old 4M value was) + * minor incompatible change: new larger values for *DEBUG-PRINT-LENGTH* + and *DEBUG-PRINT-LEVEL* + * SBCL runs on SPARC systems now. (thanks to Christophe Rhodes' port + of CMU CL's support for SPARC, and various endianness and other + SBCL portability fixes due to Christophe Rhodes and Dan Barlow) + * new syntactic sugar for the Unix command line: --load foo.bar is now + an alternate notation for --eval '(load "foo.bar")'. + * bug fixes: + ** The system now detects stack overflow and handles it gracefully, + at least for (OR (> SAFETY (MAX SPEED SPACE)) (= SAFETY 3)) + optimization settings. (This is a good thing in general, and + its introduction in this version should be particularly timely + for anyone whose code fails because of suppression of tail + recursion!) + ** The system now hunts for the C variable "environ" in a more + devious way, to avoid segfaults when the C library version differs + between compile time and run time. (thanks to Christophe Rhodes) + ** INTEGER-valued CATCH tags now work. (thanks to Alexey Dejneka, + and also to Christophe Rhodes for porting the fix to non-X86 CPUs) + ** The compiler no longer issues bogus style warnings for undefined + classes in the same source file as the DEFCLASSes which defined + them. (thanks to Stig E Sandoe for reporting and Martin Atzmueller + for fixing this) + ** fixes in CONDITION class precedence list for undefined function + errors (thanks to Alexei Dejneka) + ** *DEFAULT-PATHNAME-DEFAULTS* is used more consistently and + correctly. (thanks to Dan Barlow) + ** portability fixes aiming at bootstrapping under CLISP (thanks + to Dave McDonald and Christophe Rhodes) + ** FORMAT fixes (thanks to Robert Strandh and Dan Barlow) + ** fixes in type translation and and type inference (thanks to + Christophe Rhodes) + ** fixes to optimizer internal errors (thanks to Alexei Dejneka) + ** various fixes in the new ports (thanks to Dan Barlow) + * several changes related to debugging: + ** suppression of tail recursion, as noted above + ** stack overflow detection, as noted above + ** The default implementation of TRACE has changed. :ENCAPSULATE T + is now the default. (For some time encapsulation has been more + reliable than the breakpoint-based :ENCAPSULATE NIL + implementation, at least on X86 systems; and I just noticed that + encapsulation also seems closer to the spirit of the ANSI + specification.) + +changes in sbcl-0.7.3 relative to sbcl-0.7.2: + * SBCL now runs on the PPC archtiecture under Linux. It actually did + this as of 0.7.1.45, but was left out of the previous news section + (thanks to Dan Barlow) + * SBCL now runs on the Solaris operating system on SPARC architectures + (thanks to Christophe Rhodes's port of the CMUCL runtime) + * cleanups to the runtime on SPARC, both Linux and Solaris, and for + gcc>=3 (thanks to Nathan Froyd and Ingvar Mattsson) + * ANSI's DEFINE-SYMBOL-MACRO is now supported. (thanks to Nathan + Froyd porting CMU CL code originally by Douglas Thomas Crosher) + * The fasl file format has changed again, to allow the compiler's + INFO database to support symbol macros. + * The user manual (in doc/) is formatted into HTML more nicely. + (thanks to coreythomas) + planned incompatible changes in 0.7.x: * When the profiling interface settles down, maybe in 0.7.x, maybe later, it might impact TRACE. They both encapsulate functions, and
