changes in sbcl-1.3.0 relative to sbcl-1.2.16:
* minor incompatible change: the environment passed to a macro/setf/deftype
expander is not always an object of type SB-KERNEL:LEXENV.
It can be nil, as is permissible by the standard.
* enhancement: ported to ARM64 Linux.
* enhancement: a new interpreter is included which has many benefits
over sb-eval. It is disabled by default. See src/interpreter/README
for instructions to enable it, and further details.
* bug fix: calling COMPILE when SB-EXT:*EVALUATOR-MODE* was :INTERPRET
would fail to perform "normal semantic processing such as macro expansion"
as stipulated by X3J13 issue LOAD-TIME-EVAL.
* bug fix: SB-UNICODE:CONFUSABLE-P no longer treats "<" and the empty
string as confusable. (lp#1504739)
* bug fix: (ASSERT (COMPUTE-IT ...)) would expand incorrectly
if COMPUTE-IT was a local macro that shadowed a global function.
* bug fix: SB-POSIX:CFSETISPEED and SB-POSIX:CFSETOSPEED now work properly
on platforms that use only the minimum specified set of fields in struct
termios (verified on Linux, still known not to work on FreeBSD and NetBSD,
very probably others). (partial fix for lp#1500951)
