I think the versioning thing also affects the eggs in svn too.  For
example, suppose right now you have egg foo at version 1.0.  When
CHICKEN 5 is released, foo will be ported to CHICKEN 5.  What version
will it be in CHICKEN 4 and 5?

After we have the egg for both CHICKEN 4 and 5, how to manage new
versions?

I'm quite sure we have a solution for this problem, which is basically
the same as we had in the CHICKEN 3->4 transition.  Unfortunately, since
I was the last person I know to switch to CHICKEN 4, I didn't actually
faced that problem with my eggs.  Since nobody else was using CHICKEN 3,
I just froze egg versions for that CHICKEN version and continued to
update eggs for CHICKEN 4 only.

Another alternative would be using another .release-info file.  That
approach wouldn't require changes in henrietta-cache.

For example, we'd have

  https://raw.github.com/mario-goulart/awful/master/awful.release-info

for CHICKEN 4, and

  https://raw.github.com/mario-goulart/awful/chicken-5/awful.release-info

or

  https://raw.github.com/mario-goulart/awful/master/awful.release-info.5

for CHICKEN 5.  Of course, other variations are possible.

It'd be just a matter of pointing to a CHICKEN 5-specific
.release-info.

Best wishes.
