testing the first alpha version of the installer for the next major Debian release, Bullseye. The release is expected in about a year and a half to two years.
Key changes in the installer:
- Changed references to CD and CD-ROM to "installation media";
- apt-setup reworked generation of strings in sources.list files for security updates. The {dist}-updates lines have been renamed to {dist}-security. Sources.list allows "[]" blocks to be separated by multiple spaces;
- Stopped installation of intermediate package apt-transport-https;
- Stopped creating the my-at-spi-dbus-bus.desktop file in the user profile (at-spi2-core now always starts the at-spi bus);
- The default host for native mirrors is "deb.debian.org";
- Provided setting gfxpayload=keep parameter in the bootloader submenu, which solves problems with unreadable fonts on HiDPI screens when loading images for network installation via EFI;
- Documentation converted to DocBook XML 4.5 format
- Added definition of modules for signed images for UEFI in grub2;
- Installed the cryptsetup-initramfs package instead of cryptsetup;
- Discontinued imaging for QNAP TS-11x/TS-21x/HS-21x, QNAP TS-41x/TS-42x, and HP Media Vault mv2120 cards;
- Added support for Olimex A20-OLinuXino-Lime2-eMMC ARM board;
- mini.iso provides network boot mode in EFI for the ARM platform;
- Provided installation of packages to support virtualization systems if a launch is detected in environments under their control;
- Added thermal_sys module to Linux kernel image;
- Added virtio-gpu package for graphical output in virtual machines;
- Backported DTB (Device Tree) support for Rasperry Pi Compute Module 3.
