I see several comments bemoaning the lack of new features. This is actually not at all uncommon in Eudora betas and I've seen them add new features in blocks before release in the past.

As to the complaint that it's just bugfixes and shouldn't be 6.0, given the Eudora annual licensing model, this should not make a difference to any customers. It's not a paid upgrade in the traditional version-bump model.

Beta tests are done for the benefit of the developers. The junk filter is working well (for me, so far), which is what they probably wanted tested.

I read the readme where it said the it was very new, but I wish I had a better understanding of how content compression is supposed to work
