Canonical has finally made a public launch of Ubuntu 23.04, codenamed the Lunar Lobster, available for enterprises, work and play as it boasts improvements for enterprise developer desktops, gaming enhancements, a revamped installer, and an expanded focus on gaming.

The most unique feature to be boasted about with this launch is login management with Azure Active Directory. Ubuntu Desktop 23.04 is the first and only Linux distribution to provide native user authentication with Azure Active Directory (Azure AD) enabling users on Microsoft 365 (M365) Enterprise plans to authenticate Ubuntu Desktops with the same credentials they use for M365 or Azure.

“This Ubuntu milestone release demonstrates our progress in raising the bar for the enterprise developer desktops, thanks to our best-in-class Linux integration with Active Directory Domain Services and now Azure Active Directory”, said Mark Shuttleworth, CEO of Canonical. “Our expanded investment in Ubuntu gaming means your downtime is just as satisfying”.

Apart from teh Azure Active Directory support, the new release comes packed with many more new features and improvements. Some of the best new features include:

• New installer scales up desktop deployments
• Improved workflows for cross-platform development
• More controls for apps and snaps
• Levelling up the Ubuntu gaming experience
• Linux kernel 5.16
• GNOME 44
• Improved support for AMD and NVIDIA graphics cards

However, it is not a Long-Term Support version. Ubuntu 23.04 will be supported for nine months until January 2024. You can upgrade to Ubuntu 23.10 (upcoming version) if you want an up-to-date and secure system after its end of life.

Go ahead and download Ubuntu 23.04 to test it out on your machines.
