We've done some fixing and balancing based on your feedback on 1.24 and are posting an update for you to try (no editor yet though)! Lots of cleanup on air combat, added (fixed?) the ability for subs to patrol a region and attack any enemies that enter, and balancing work on diplomatic relations, stability, and more. If you want to try it out just click "Pre-release Update" in the Options in the launcher and have a look at the release notes here. Feedback on the changes (and anything else) would be greatly appreciated!
UPDATE: New version posted 10/14/11, release notes updated.
UPDATE: New version posted 10/20/11, release notes update (an paratrooper exploit gone!).

UPDATE: New version posted 11/10/11. Fixed region improvements costs, removed obsolete (and broken) Client Process option from Mac version.
