Because of the new features provided by MailChimp in their API announcements, some planned changes to the .NET wrapper were delayed until a future release.
I figured that that the new features would be more beneficial than some of the lower priority items on the to-do list. Those items will be included in the next release.
Segmentation options in MailChimp Api announcement 2009-10-02
MailChimp Api v1.2.3 functionality supported (ann. 2009-10-26)
MailChimp Api v1.2.4 functionality supported (ann. 2009-11-24)
Cleanup of PerceptiveMCAPI.Types.Internal namespace and more consistent approach to complex return values from the Api (phase 1)
1) Numerous improvements to the get & show user controls
2) Remove 'Reset apikey' button and provide a 'select' option on 'apikeys' method result set (active only) to choose a specific apikey. Default apikey (if defined) in .config file will still be used on page intialization.
