16.1. Upcoming Developments
Now that Debian version 10 is out, the developers are already busy working on the next version, codenamed Bullseye…
There is no official list of planned changes, and Debian never makes promises relating to technical goals of the coming versions. However, a few development trends can already be noted, and we can try to guess what might happen (or not).
In order to improve security and trust, an increasing number of packages will be made to build reproducibly; that is to say, it will be possible to rebuild byte-for-byte identical binary packages from the source packages, thus allowing everyone to verify that no tampering has happened during the builds. This feature might even be required by the release managers for testing migration.
In a related theme, a lot of effort will have gone into improving security by default, with more packages shipping an AppArmor profile.
Of course, all the main software suites will have had a major release. The latest version of the various desktops will bring better usability and new features. Wayland, the new display server, will likely obsolete X11 entirely.
With the widespread use of continuous integration and the growth of the archive (and of the biggest packages!), the constraints on release architectures will be harder to meet and some architectures will be dropped (like mips, mipsel and maybe mips64el).
