removed an obsolete upgrade issue; partially adapted features, changes, and issues from the Bullseye release notes. Let me know if I've made a mistake.

What's new in the Bullseye release?
This page is still a work in progress.
For additional information see:
Bullseye is still in the testing stage. Any issues that appear here may be resolved before the release. As usual, any pre-release software is to be used at your own risk.
Printers connected over USB can be treated as network devices via the new ipp-usb package, extending driverless printing to include USB-connected printers.
A generic open command is provided as a convenience alias to either xdg-open (by default) or run-mailcap. This can be changed through the update-alternatives system.
- The Fcitx input method, often used for inputting CJK characters among others, has been upgraded from Fcitx 4 to Fcitx 5, enabling Wayland support.
Support for exFAT filesystems is now a part of the kernel, rather than requiring use of the separate FUSE driver. If you wish to continue using the older implementation, you must use mount.exfat-fuse instead of mount.exfat Tools provided as part of the kernel driver are in the exfatprogs package, conflicting with the older independent tools in exfat-utils.
The GNOME Flashback desktop environment can now be installed as part of the task-gnome-flashback-desktop package, and is newly available in the installer when selecting a desktop.
The win32-loader software, which enables Debian installation from Windows without use of separate installation media, now supports UEFI and Secure Boot.
The Panfrost and Lima drivers are now available, enabling free support for the GPUs present in many ARM devices.
The format of the /etc/apt/sources.list line for the security repository has changed. It should look something like this:
deb http://security.debian.org/debian-security bullseye-security main
- Note that the security repository has no packages while bullseye is still in the testing stage. Having the correct entry will prepare you for the release, though.
Debian 11 uses control groups v2 (cgroupsv2) by default, providing a unified resource-control hierarchy. Legacy cgroups can be re-enabled.
Intel GPUs based on the Broadwell architecture and newer will now default to the intel-media-va-driver driver for video decoding, if installed. This can be overridden with an environment variable to force the legacy driver on supported hardware. See the HardwareVideoAcceleration page for more information.
Password hashing for local system accounts now uses yescrypt by default instead of SHA-512. This provides improved security. Change passwords with the passwd command to take advantage of this.
If you previously ran bullseye during its time as "testing", you may see this error when you run apt-get update:
E: Repository 'http://deb.debian.org/debian bullseye InRelease' changed its 'Suite' value from 'testing' to 'stable' N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
In order to accept this change, you should run apt update instead, at least once. It will prompt you for confirmation, and then everything will proceed as normal.
Support for the barrier and nobarrier mount options has been removed from the XFS filesystem. It is recommended to check /etc/fstab for the presence of either keyword and remove it. Partitions using these options will fail to mount.
redmine is unavailable, as it did not migrate to the latest version of Ruby in time for Bullseye's release. It will be made available via Backports as soon as possible. Users of the package are advised to either delay the upgrade until this is done, or use a Buster VM/container to isolate the application.
Some options in rsync have been renamed. If you're using it to transfer files between Buster and Bullseye as part of your upgrade process, and you're making use of the --copy-devices (now --write-devices) or --noatime (now --open-noatime) flags, you're required to install rsync from buster-backports and use the newer options.
