Tra le principali innovazioni presentate in Ubuntu 21.04 "Hirsute Hippo" possiamo vedere che il raffinato kernel Linux è stato aggiornato alla versione 5.11 , che include il supporto per l'enclave Intel SGX, un nuovo meccanismo per intercettare le chiamate di sistema, un bus di aiuto virtuale, un rapido filtraggio di chiamate di sistema in seccomp, cessazione del supporto per l'architettura ia64, trasferimento della tecnologia WiMAX al ramo di staging, capacità di incapsulare SCTP in UDP.
Mentre per la parte desktop, è inclusa la versione 3.38 di GNOME , ma con la caratteristica che contiene applicazioni GNOME sincronizzate con lo sviluppo di GNOME 40.
Questa decisione di non includere la versione 40 è stata dovuta agli sviluppatori Canonical che hanno affermato che il passaggio alla nuova versione è stato ancora troppo presto.

Ecco l'elenco di tutti i rilasci via Distrowatch.
Ubuntu 21.04 "Hirsute Hippo".
Canonical has released Ubuntu 21.04 which carries the code name "Hirsute Hippo". The distribution's new version ships with GNOME running on a Wayland session as the default desktop and includes the built-in ability to join Active Directory domains. "Ubuntu machines can join an Active Directory (AD) domain at installation for central configuration. AD administrators can now manage Ubuntu workstations, which simplifies compliance with company policies. Ubuntu 21.04 adds the ability to configure system settings from an AD domain controller. Using a Group Policy Client, system administrators can specify security policies on all connected clients, such as password policies and user access control, and Desktop environment settings, such as login screen, background and favourite apps. Ubuntu 21.04 uses Wayland by default, a significant leap forward in security. Firefox, OBS Studio and many applications built with Electron and Flutter take advantage of Wayland automatically, for smoother graphics and better fractional scaling." Additional details can be found in the distribution's release announcement and in the release notes.

It uses the Materia theme and the icons are Papirus icons. Studio Controls has seen further development as its own independent project and has been updated to version 2.1.4. Ardour 6.6+ (a future 6.7 snapshot). Ardour has been updated to version 6.6+, meaning this is a git snapshot of what will eventually be Ardour 6.7. This had to be done because Ardour 6.5 started to fail to build with a newer library introduced into the Ubuntu archives, and could only be resolved with this snapshot. We hope to have Ardour 6.7 in via official updates once released. Agordejo is new to Ubuntu Studio this release. It was brought-in for those unsatisfied with RaySession's audio session management but found New Session Manager's interface to be too old and clunky."
