Richard Thomas has a suggestion for the Zend Framework development group - clean out the attic before you hit the 2.0 mark.
A big focus of 2.0 it seems is going to be performance and cleaning up the structure to make use of php 5.3 features which is great, I have been preaching the need for ZF to start taking performance as a real concern for a while now. On the other hand they have gotten to a certain point that they need to reflect on what they already have and not let the spiderwebs grow to large.
Richard points out that the Zend Framework, which has a focus on being a "business-class framework" and having the best to offer, has quite a few parts of it that are older and aren't well maintained. This sort of thing could cause some big problems down the line and could even cause some doubt over the developer's choice of frameworks.
