What directory structure changed heavily between 1.1.1 and 1.1.2?  What
applications "refused to run"?  1.1.1 actually fixed a lot of problems
that were in 1.1.0.  The only problem with it, that I am aware of, was
the binmode/textmode stuff.

1.1.3 has Corinna's fixes to avoid accessing the network, which should
speed up things for some people.  That's why we're trying to get it
released.

The "binary incompatibility" that has been introduced is no different
than what we have done before.  Newer versions of cygwin1.dll will
still work with older binaries.

If it is a tremendously huge deal, I can "fix" the library code to make
it backwards compatible.  I usually tend to adopt a "wait and see" attitude
for this kind of thing, though.  It may be a big non-issue.

The older versions of packages are always available in the "old"
directory.

It is a colossal, large asteroid sized wish that there will be
volunteers available to do this.  We have only about four people
actively contributing anything to the cygwin DLL right now.  DJ,
Corinna, and I already have to worry about various Cygwin releases in
our full-time jobs.  I doubt that any of us wants to add something like
a "stable" branch to the mix.

If this change to libcygwin.a causes massive heartache on the cygwin
mailing list, I will fix it.

I don't want to muddy the waters with a "supported" and "experimental"
branch three months after the release of 1.1.x.  We're still fine tuning
how we are doing things.  I'm trying to make up for the time that we
lost during the relatively static B20.1 period.

Eventually things will either settle down or someone will implement the
site that you're talking about.  I doubt that DJ, Corinna, or I will
be the ones setting it up, though.
