WordPress just becomes more and more powerful, it’s very hard to keep up with new features. Thankfully there are several very active people behind great blogs, who write very well explained tutorials and premade code snippets to let you learn everything in very easy way. Today I made my exercise to find such sites and articles, which are very new and WordPress 2.8. compatible. There are really long list with new features, you can check them in first link from WordPress Codex, so make sure you can keep up!
