Windows/Mac/Android/iPhone/Blackberry/Web: Trillian, the cross-platform, message-syncing IM client has made its service even better by releasing all their clients with Pro features for free with advertisements.

Windows only (for now): Instant messaging services often have clients for multiple platforms. But keeping them open across machines and portable devices can be a nightmare: lost chats, automatic "away" statuses, different histories and so on. The latest Trillian build fixes that with a "continuous" IM stream.

Android: Those of you waiting for a more stable client (or with phones that didn't allow sideloading) can finally test out Trillian for Android, on of our favourite (and your favourite) multi-protocol IM clients.

Mac only: Trillian's stepped up its multi-protocol game significantly on the Mac platform, fixing a whole bunch of items missing or jaggy in the alpha release, and adding Facebook and Twitter integration, Growl notifications, a better chat history layout and more.

Android: The desktop version of Trillian Astra is one of our favourite desktop IM clients, and now you can get the same polished, account-syncing, tabbed-messaging IM client on your Android phone.

Windows only: Trillian 5 Beta is a very slick-looking multi-chat client, and it makes being signed into 10 networks at once seem manageable. If you're one of Trillian's many fans, you owe yourself a test drive of this new version.

Windows: The extremely popular instant messaging application Trillian just released a new beta, adding direct replies to emails and tweets via notification popups, instant URL previews (you won't get duped by rickrolls or NSFW links) and more Wikipedia data for quick lookups.

Mac OS X: Trillian, the slick-looking multi-protocol IM client has launched an early alpha for Mac OS X. It's not close to feature-complete, but it does look like Trillian.

Windows: Trillian, a favourite instant messaging client with Lifehacker readers, is out with a 4.1 beta that ups its Twitter and Facebook functionality, integrates Windows 7 interface features, and smoothes out the already slick interface.

Windows only: If our recent coverage of the Digsby-debacle has you down in the dumps over the departure of Digsby from your hard disk, you might want to check out Triillian Astra—fresh from beta and ready to go.

Windows: Trillian Astra, the app that wants to manage all your social network updates, chat protocols and email notifications, has opened its beta to anyone who wants in.

We're not sure how permanent it is, but Trillian's apparently giving out invites for their Trillian Astra client—Windows version only—almost immediately after you apply.
