Precise Pangolin is the Ubuntu codename for version 12.04 of the Ubuntu Linux-based operating system. Officially released in April 2012, Precise Pangolin follows the Natty Narwhal (v11.04) release and serves as a major update for Ubuntu, with new cloud computing storage features via the Ubuntu One service as well as long term support (LTS), Metal-as-a-Service (MaaS) support and a number of other enterprise-focused additions and enhancements.
Precise means “sharply defined or stated,” and the pangolin is a scaly anteater indigenous to tropical regions of Africa and Asia. The Precise Pangolin release of Ubuntu was succeeded by Quantal Quetzal in October 2012.
