In the past week Ubuntu 21.04 "Hirsute Hippo" release announced, which is classified as a provisional version, whose updates are formed in 9 months (support will be carried out until January 2022).

This new version of Ubuntu 21.04 includes a number of quite important changes which are beginning to set the course that is being taken towards the next LTS version of the system and it is that even though this version did not include GNOME 40 if we can find many new features.

Main new features of Ubuntu 21.04 "Hirsute Hippo"

This new version of Ubuntu arrives with GNOME Shell 3.38 using GTK3, But using GNOME 40 applications, besides whate Linux kernel has been updated to version 5.11, which includes support for Intel SGX enclaves, a new mechanism for intercepting system calls, a virtual helper bus, prohibiting compilation of modules without MODULE_LICENSE (), fast filtering of system calls in seccomp, termination of support for the ia64 architecture, transfer from WiMAX technology to "staging" branch, the ability to encapsulate SCTP in UDP.

On the appearance side, we can find that a new dark theme for Yaru has been proposedIn addition, the icons have been updated to identify the types of files.

As well the home directory access model has been changed of the users in the system; home directories are now created with 750 permissions (drwxr-x -), that grant access to the directory only to the owner and members of the group.

On the desktop, we can find the ability to move resources from applications using drag and drop method and in the settings, you can now change the energy consumption profile.

Active Directory integration improved and the ability to authenticate users to Active Directory with GPO (Group Policy Objects) support was provided immediately after installing Ubuntu.

Administrators can manage Ubuntu workstations by hosting settings on an Active Directory domain controller, including desktop settings and a set of suggested applications. The GPO can be used to define security policies for all connected clients, including configuring user access parameters and rules for registering passwords.

Another novelty that stands out is that it was added Pipewire Media Server support to enable screen recording, improve audio support in sandbox applications, provide professional audio processing capabilities, eliminate fragmentation, and unify the audio infrastructure for different applications.

The installer has added support for creating spare keys to restore access to encrypted partitions, which can be used to decrypt if the password is lost, plus improved support for UEFI SecureBoot on x86_64 (amd64) and AArch64 (arm64) systems is also highlighted.

The layer for organizing verified boot has been transferred to the use of the SBAT (UEFI Secure Boot Advanced Targeting) mechanism, which solves problems with certificate revocation. SBAT support has been added to the grub2, shim, and fwupd packages. SBAT involves adding new metadata, which is digitally signed and can also be included in the allowed or prohibited component lists for UEFI Secure Boot.

Regarding the compilations of Raspberry Pi, in this new version of Ubuntu 21.04, the support for Wayland is included. GPIO support added (via libgpiod and liblgpio). Compute Module 4 boards now support Wi-Fi and Bluetooth.

Also in this new version of Ubuntu 21.04 for desktop, by default, a session based on the Wayland protocol is enabled. When using proprietary NVIDIA drivers, by default, as before, an X server-based session is offered, but for other configurations this session is carried over to the options category.

It is noted that many of the limitations of the GNOME session on Wayland have recently been removed, which have been identified as issues blocking the transition to Wayland. For example, it is now possible to share a desktop using the Pipewire media server.
