Ubuntu 18.10 "Cosmic Cuttlefish" is now available. This release features a new shiny theme called "Yaru," originally intended for Ubuntu 18.04 LTS. The new GNOME 3.30 also improves desktop performance.
Most improvements in Cosmic Cuttlefish are low-level things you can not see. As usual, this means a lot of package upgrades. Ubuntu 1
There is a new one on the desktop Standard theme named "Yaru" which contains a new icon set called "Suru". This theme was created by the Ubuntu community and was known at one point as "Communitheme".
It already looks shiny new, and it should be nicely polished if it becomes the default theme for LTS users in Ubuntu 20.04.
The traditional Ubuntu theme, known as Ambiance GTK, is still available in the Ubuntu package repositories, if you want it. 19659002]
OMG! Ubuntu! reports that the Ubuntu 18.10 desktop feels much faster than Ubuntu 18.04 LTS. Not surprisingly, GNOME Shell developers have been working to improve performance and reduce resource consumption for GNOME 3.30. And since Ubuntu 18.10 now includes GNOME 3.30, the Ubuntu users now benefit from it all.
Like Joey Sneddon at OMG! Ubuntu! It puts in its review:
I have no hard values to back it up, and it's based solely on my own personal experience, but Ubuntu 18.10 feels much faster than 18.04.
For the average Ubuntu user, we recommend staying with Ubuntu 18.04 LTS. It's a long-term service release, meaning it's supported with updates for five years. This is the stable, stable version that does not let you upgrade too often.
Ubuntu releases new "stable" versions every six months, but new long-term service releases only every two years. These stable versions are only supported with updates for nine months. You need to upgrade to a new version of Ubuntu every six months with this release track.
