+ the manual for details; for now, package locks can be disabled by
+ removing :SB-PACKAGE-LOCKS in customize-target-features.lisp, but
+ if no major problems are found then it is likely that they will be
+ compiled in unconditionally.
+ * major incompatible change: LOAD-FOREIGN and LOAD-1-FOREIGN are now
+ unsupported operators on all platforms. To load a shared library
+ into SBCL, use SB-ALIEN:LOAD-SHARED-OBJECT. To load a non-shared
+ object file, link it into a shared library outside of SBCL and
+ load it using SB-ALIEN:LOAD-SHARED-OBJECT. (incidentally fixes
+ bug #79)
+ * bug workaround: ROOM T and the GC were not working together
+ reliably, because invariants expected by the SB!VM:INSTANCE-USAGE
+ reporting facility aren't preserved. That reporting has been
+ disabled, so now until and unless someone figures out how to make it
+ work reliably with the current GC, (ROOM T) is equivalent to (ROOM).
