Ubuntu being an open source initiative is bound to be a constantly changing environment. There have been around 14 releases of Ubuntu so far and the 15th is all set to roll out in October of 2011. The upcoming entrant nicknamed the Oneiric Ocelot has been reviewed and previewed by many Linux geeks and has been found to be very efficient.
All its Alpha and Beta releases have ensured the fixing of majority of the bugs arising during user testing. We expect the final version to be released soon to incorporate a new look and feel in the Ubuntu Line-Up.
LTS is an abbreviation for “Long Term Support”.
We produce a new Ubuntu Desktop and Ubuntu Server release every six months [diagram below]. That means you'll always have the latest and greatest applications that the open source world has to offer. Ubuntu is designed with security in mind. You get free security updates for at least 18 months on the desktop and server.
A new LTS version is released every 2 years. In previous releases, a Long Term Support (LTS) version had 3 years support on Ubuntu (Desktop) and 5 years on Ubuntu Server. Starting with Ubuntu 12.04 LTS, both versions will receive 5 years support. There is no extra fee for the LTS version; we make our very best work available to everyone on the same free terms. Upgrades to new versions of Ubuntu are and always will be free of charge.
To support our goal of ensuring stability, we plan to make a small number of changes to the release schedule:
- Reduced Alpha Stage: Because we will have substantially less new code, we can reduce the number of Alpha releases, and extend the Beta stage to allow for more system testing.
- Two Beta Releases: We generally get more bugs filed in the Beta stage because of the increase in user base. In order to address more of these issues, we will provide an additional Beta release.
The schedule of the release of Ubuntu 12.04 with exact date is as follows.
- Alpha 1 release date: December 1st 2011
- Alpha 2 release date: February 2nd 2012
- Beta 1 release date: March 1st 2012
- Beta 2 release date: March 22nd 2012
- Release Candidate release date: April 19th 2012
- Ubuntu 12.04 Final release date: April 26th 2012
