3.0 upgrading and custom fields?
What will the upgrade proccess be for 3.0 for custom fields? I'm looking at building a custom hack that lets users fill out pedigree data for their ad (for a horse website). Should I forego spending time & effort on working on it? Will all my custom fields' data upgrade nicely and be able to be displayed on the new system? Will 3.0 bring anything new to the custom fields area? Thanks!
