Greetings, Jon,
* Add depends: to version descriptions
This is a version-specific list of required packages (as opposed to
requires:, which is per-package, and contains the union of the dependencies
for all versions).
I believe that historical setup versions will either ignore, or can handle
depends: (just containing package names, without version relations)
relatively sanely (see [1] et seq. for details).
As long as the behaviour you outline in [1] is consistent, then that means
I should be able to use older Setup with newer setup.ini, yes? That will
be useful for people who use the Time Machine. :)
* De-duplicate source archives
Source archives which are identical[2] between x86 and x86_64 will be moved
to paths starting src/ in the release area.
I'm not quite visualizing this, Do you mean there will be a new directory
name 'src' that will be on the same level as 'x86' and 'x86_64' or
will it be higher up the directory tree? It matters to me for the Time
Machine as I'll need to be able to re-create the same directory hierarchy
for each circa. It's a selectively automated process currently, but I
need to know what symlink to place where. :)
Doing post-hoc de-duplication is unfortunate, but worthwhile given the
potential size saving in mirrors (see [3] et seq.), until cygport can be
taught how to make suitable source packages (which has several unresolved
issues, also discussed at [3], [4] et seq.).
Will this be done en masse upon the next setup.ini build cycle, or over
time as each new package is updated? Having a massive amount of "new"
packages show up under a "new" directory named 'src' will be quite a lot
for the mirrors to absorb all at once. For the Time Machine it might
effectively be double as I have to maintain the old hierarchy as well as
the new one (under the assumption that you'd apply the de-duplication
retroactively).
* Migrate from setup.hint to pvr.hint in release area
I also plan to migrate all remaining setup.hints to pvr.hints in the release
area (setup.hint in uploads have been automatically migrated since [5]).
This should have no effect on the generated setup.ini, but enables some
complexity (some of which isn't implemented properly, see [6]) to be removed
from calm.

[2] my current implementation considers two archives identical if they have
an identical set of members, with identical contents. Permitted differences
include the mtime, mode or owner of members.
