Happy New Year to all Ubuntu fans! The year 2014 has just started, and we already have to say goodbye to the Ubuntu 13.04 (Raring Ringtail) Linux operating system, which reaches end of life on January 27.Adam Conrad has announced earlier today, January 7, that the Ubuntu 13.04 Linux operating system, also known as Raring Ringtail among its fans, will reach end of life (EOL) on Monday, January 27, 2014, as Canonical will no longer provide security/critical fixes and software updates for it.
“This was the first release with our new 9 month support cycle and, as such, the support period is now nearing its end and Ubuntu 13.04 will reach end of life on Monday, January 27th. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 13.04,” Adam Conrad said in the official announcement.
Announced 9 months ago, on Thursday, April 25, 2013, Ubuntu 13.04 (Raring Ringtail) was the first Ubuntu release to introduce an official GNOME flavor, which is powered entirely by the GNOME 3 desktop environment. In addition, Ubuntu 13.04 also introduced the first ever official Chinese flavor, called Ubuntu Kylin.
Ubuntu 13.04 was powered by Linux kernel 3.8, Unity 7, Upstart 1.8, X.Org 7.7, X.Org Server 1.13.3, Mesa 9.1.1, Python 3.3, Compiz Fusion 0.9.9, and the GCC 4.7.3 toolchain. It also included up-to-date applications (for that time), such as the Mozilla Firefox 20 web browser and the Mozilla Thunderbird 17.0.5 email/RSS client.
