Ubuntu celebrating it’s 10th birthday and in this occasion they codenamed their next Ubuntu development version after a monkey Vivid Vervet.
During the announcement Ubuntu Founder Mark Shuttleworth said in his blog post;
“Vexatious at times, volant and vogie at others, a vervet gets in anywhere and delights in teasing cats and dogs alike. As the upstart monkey in this business I can think of no better mascot. And so let’s launch our vicenary cycle, our verist varlet, the Vivid Vervet!”
As you know, Ubuntu 14.10 “Utopic Unicorn” due out later this month and Mark announced the code name for next development version of ubuntu, Keeping the project in time frame same as before.
I expect the official release of Ubuntu 15.04 Vivid Vervet will be in April 2015 but in mean time you can look for Ubuntu 14.10.
