Ubuntu 10.04 LTS (Lucid Lynx) has arrived officialy, Ubuntu 10.04 is a long-term support (LTS) release. A Typical Ubuntu versions get 18 months of updates, but LTS releases are supported for 3 years on desktop computers and 5 years on servers. LTS are low on new Features.

Features of Ubuntu 10.04 LTS (Lucid Lynx)

1. Social Apps and the “Me” Menu

Lucid gets a nice social Networks Integration with ‘Social From The Start’ initiative powered by open source project Gwibber. Its a nice client, for social networks like Twitter, Facebook, Flickr, or FriendFeed, with desktop notifications of replies and messages, and a very elegant view of all your messages at once.

2. Cloud Sync and Ubuntu One

This time Ubuntu One brings a commercial cloud synchronization service to the Ubuntu desktop. Major parts being mobile synchronization (iPhone, Android, others) and a New Music store (iTunes Alternative) whih wors with popular Ubuntu player: Rythmbox.

Ubuntu One makes a lot more sense. When you buy music from the store, it’s automatically synced into your Ubuntu One space, and can then be downloaded onto at least three other computers that aren’t running Ubuntu One. Your contacts on mobile devices, and from email desktop clients, should theoretically be hooked together too, and Ubuntu One looks a lot more like a Dropbox clone that makes Ubuntu work better.

3. Start fast with Ubuntu

Ubuntu loads quickly on any computer, but it’s super-fast on newer machines. I didn’t notice it on the first, second, or maybe even third start-up of the Ubuntu daily build I’ve been using for the past week, but now Ubuntu 10.04 starts up at a pretty unbelievable pace.

4. Visual Improvements

Lucid Lynx dropped the human Gnome theme and adopts a new dark Ambiance theme, and
Redesigned Shut Down, Log Out and Restart dialogs, Ubuntu software Center now has a new design as well as a “Featured Applications” category as well as many other improvements!
