I’m just curious to hear from authors of older Wordpress themes (2.9 and before) on whether or not you guys/gals are going back and upgrading all of your older products to be compatible with the new 3.0 features. I know I am doing this on my themes, but it’s turning out to be quite a time consumer – anyone else experiencing the same? Anyone ignoring updates altogether?
For buyers: is a 3.0 update a make it or break it deal when you purchase themes nowadays?
Thanks in advance for any insights you guys might have
