If I've done everything correctly, SBCL 1.0.28 should be available for
download from Sourceforge.
changes in sbcl-1.0.28 relative to 1.0.27:
* a number of bugs in cross-compilation have been fixed, with the ultimate
result that building under (at least) clisp should be much more reliable.
* minor incompatible changes: echo-streams now propagate unread-char to the
underlying input stream, and no longer permit unreading more than one
* improvement: on x86/x86-64 Lisp call frames now have the same layout as C
frames, allowing for instance more reliable backtraces.
* improvement: the debugger REPL can now reference lexical variables
by name directly for code compiled with (DEBUG 3).
* improvement: errors from malformed declarations now have better source
paths associated with them. (thanks to Tobias Rittweiler)
* optimization: faster local calls on x86/x86-64
* bug fix: some error messages for out-of-bound array indexes confused the
index and the bound. (thanks to Stas Boukarev)
* bug fix: pretty printing malformed DEFPACKAGE forms (thanks to Sidney
* bug fix: running regressions tests in shells without OSTYPE set now works.
(reported by Harald Hanche-Olsen)
* bug fix: more robust static space exhaustion signalling from
MAKE-STATIC-VECTOR (thanks to Daniel Lowe)
* bug fix: (SETF DOCUMENTATION) for anonymous function now throws the
docstring away instead of storing it under names such as (LAMBDA (X)).
(reported by Leslie Polzer)
* bug fix: timers could go off in the wrong order, be delayed indefinitely
(thanks to Ole Arndt for the patch)
* bug fix: RESTART-FRAME and RETURN-FROM-FRAME stack corruption
* bug fix: the discriminating function for PRINT-OBJECT no longer preserves
potentially-invalid effective methods in its cache.
* bug fix: SB-INTROSPECT:FIND-DEFINITION-SOURCE now works with funcallable
instances as well (thanks to Paul Khuong)
* bug fix: using RUN-PROGRAM does not interfere with SB-POSIX:WAIT,
SB-POSIX:WAITPID and their C equivalents.
* bug fix: RUN-PROGRAM does not crash on Darwin when stressed.
