Would someone please post some information with respect to how the revised
CLtL fits into the general Common Lisp scheme of things? E.g., does it reflect
the ANSI CL? Do any current CL implementations follow the revisions/clarifications
in the new CLtL? [, does MACL 1.3 follow this revision, or is that
going to wait for 2.0?]

The only changes to the original text in CLtL2 will be to fix typos, bad
grammar, and obvious technical errors. The work of the ANSI CL committee
is reflected in set-off sections that describe how a feature would be
changed by adoption of an X3J13 proposal. There are also new chapters
describing the new, large features being added to the language (the
condition system, full-featured LOOP, and a brief description of CLOS
(referring the reader to Sonya Keene's book for more info)). There will
also be an appendix about Dick Waters's Sequence Expression facility, which
is not being adopted at this time.

What is the condition system?
;full-featured LOOP,
Will this differ from the MIT Loop macro?

Macros and functions for signalling and handling errors and other
unexpected situations. It's patterned after the Symbolics condition
handling system, but the names and syntax of many operators and conditions
have been changed.

It's mostly the same. A few features have been added (such as the OF-TYPE
preposition for declaring types using Common Lisp type specificiers), some
descriptions have been clarified, and a few obscure features have not been
included. We also didn't include the facilities for writing user-defined
LOOP paths (DEFLOOP and DEFINE-LOOP-PATH). Most of the features that were
removed or clarified already differed between various LOOP implementations;
most portable uses of LOOP should port to the ANSI version.

Is the 2nd edition of CLtL available yet? Any idea when it will be?
Thanks.

It's at the publisher now. Probably available in a month or so.
