Yes, I forgot to CC. Sorry.

Yes, I saw that but the announce was after the deletion. Thats is why I

The configuration relied on the versions on Magma, given that that is
the official repository for released configuration.

Yes, I do now, I found that the changes are in fact small but that was
too late in sunday and I had no more energy after creating the other
configurations and testing that loaded correctly.

Yes, nobody has said that they aren't going to be merged, it is just
that for Pharo 1.2 is frozen right now. So no new code can be added, it
will be added to 1.3 that recently opened to development. That is the
reason that I said that a little package with the changes will be
uploaded to some repository and used as a dependency for Magma on
Pharo1.2. For Pharo1.3 it won't be necessary.

Nothing to thank, I really want Magma on Pharo healthy, just that those
months I have had little time to maintain the configuration and the
weekend that I dedicated to it, it was too late when I discovered the
WeakOrderedCollection issue (especially because I had also to prepare
the fix to Pharo and report it. So I choose to sleep because next day is
I hope this weekend I will finally finish the work and report the
enhancement to Pharo to be applied to Pharo1.3.
