As compared with The alpha release introduces the following changes:
- Support for verified boot (UEFI Secure Boot) is enabled for the amd64 architecture. To ensure the operation of Secure Boot, the Shim bootloader is used, certified by a digital signature from Microsoft (shim-signed), in combination with the certification of the kernel and the grub bootloader (grub-efi-amd64-signed) with the project's own certificate (shim acts as a layer for the distribution kit to use its own keys). Unlike previous builds, a certified working certificate was used, which can be used without manipulating the addition of a test certificate;

- Added support for Hedo MobiLine braille displays;
- cryptsetup switched to the LUKS2 disk encryption format (previously used LUKS);

- Stopped passing the BOOTIF kernel parameter for already installed systems;
- Added the ability to use several consoles at the same time during the installation process;
- For armhf/efi, GPT partitions are enabled by default;
- Added images for Novena and Banana Pi M2 Berry boards (armhf);
