there is a tentative new distribution at http://www.vitanuova.com/inferno/net_download4T.html

i haven't yet had a chance to sort out the troubles with FreeBSD 5.3-CURRENT
just because when i reassembled bits from several old machines yesterday to
build a new one for 5.3, it stopped working (power supply i think).
i might get back to that tomorrow after some urgent work.

there are a few minor changes and additions.  many of those are
part of a preparation for changes to the security/auth implementation.
(those will appear in the next distribution, which might be as early
as next week, but i wanted to push out some of these first in the existing
structure.)

i've started revising the papers, and adding some that have
been hidden in electronic desk drawers but might be of interest.

the significant change this time is the addition of
function reference types and values to this Limbo implementation.

charon has started working again on some web sites such as gmail, the bank
and credit card sites i use [with one microsoft-obsessed exception],
and works for the first time on sites that use javascript with for(... in ...).
(there's an amazing grammatical hack in the Ecmascript standard to get that to work,
which we now do.)

the CHANGELOG follows.  it's apparently in random order because
of the way it was produced (even though it wasn't a random process
that generated it).  i'll collate things next time.
