It's been a long time coming, but the final release of FeedDemon 3.0 is finally here. If you're using FeedDemon 2.x or a pre-release of FeedDemon 3.0, simply install the final release on top of the previous version. There's no need to uninstall first.
As most of you know, the biggest change in the new version is Google Reader synchronization, which replaces the now-defunct NewsGator synchronization that existed in previous releases. The first time you run FeedDemon 3.0, you'll be asked whether to convert your NewsGator subscriptions to Google Reader. The conversion may take a few minutes, but I think you'll like how much faster synchronization with Google Reader is once the conversion completes. If you tried an older pre-release of FeedDemon 3.0 and found sync to be slow, then you really should get the final release. Sync is much faster now.
FeedDemon 3.0's tagging goes a step further than you've probably seen in similar features, because it suggests tags based on the article's content and highlights tags you've used before if they seem appropriate for the article. Here's a screenshot which illustrates this feature in action:
FeedDemon 3.0 makes adding an article to your Google Reader shared items as simple as possible – a single click is all it takes. Plus, you can drag-and-drop hyperlinks and browser tabs into your shared items, so you can share almost anything you find on the web. You can also easily add a comment to your shared item.
In addition to Google Reader synchronization, FeedDemon 3.0 greatly improves the way Twitter feeds are handled. Author names, hashtags and @replies are automatically hyperlinked, and mousing over a short URL shows you where it really goes. You can also subscribe to password-protected Twitter feeds in FeedDemon, which is something you can't do in web-based RSS readers.
But my favorite new feature has to be the faster, sleeker, more informative user-interface. FeedDemon 3.0's new subscription home shows an overview of your feeds, and highlights popular articles and YouTube videos in the feeds you're subscribed to.
And FeedDemon's popular newspaper view has been simplified, so you can quickly see what you want to read without an overload of toolbuttons getting in the way.
One of the features in FeedDemon 3.0 I've seen highlighted in several blog posts (including this really well-done one by Amit Agarwal) is the ability to easily create keyword search feeds, which has actually existed for quite a while. Just enter a keyword and choose a search engine (Bing, Google, Techmeme, Twitter, YouTube, etc.), and FeedDemon will subscribe you to a feed containing the latest search results for that keyword.
There's a whole lot more I could talk about (such as FeedDemon 3.0's new SQLite backend, which makes everything much faster than before), but I figure if you made it this far, you've heard enough :) If you really want to know everything that's new, check the release notes for a detailed list of changes. Suffice to say, I consider FeedDemon 3.0 to be the most significant release since the very first version, and I hope you're as pleased with it as I am.
