Deepin 15.8, released last month, is loaded with more efficient layout tweaks that give the distribution greater functionality and maturity. Deepin, based in China, shed its Ubuntu base when with the 2015 release of version 15, which favored Debian Linux. That brought numerous subtle changes in the code base and software roots. Ubuntu Linux itself is based on Debian. The chief distinguishing factor that accounts for Deepin’s growing popularity is its homegrown Deepin Desktop Environment.
