Due to the number of changes in WordPress 2.7, it is likely that once it is released, a number of people will quickly upgrade only to find that there theme is now broken or some plugin they rely upon no longer works correctly.
Fortunately, thanks to the availability of WordPress 2.7 beta, many plugin authors have gotten a jump on making their popular plugins compatible (or were able to confirm their plugins work fine with WordPress 2.7), and have been compiling a huge list of WordPress plugins which have been confirmed to be compatible with WordPress 2.7. If you plan to upgrade around release time, you’ll first want to determine which plugins you can’t live without and verify they are all included on this list. If any aren’t on that list that you need, you’ll want to hold off on upgrading.
Note: You can now also confirm compatibility of some WordPress themes as well.
