Devuan release codenames are chosen from the Minor Planet Center Names List. The first Devuan stable release, Jessie, mirrors Debian’s Jessie (a Toy Story character). Future release names follow in alphabetical order starting with the letter A, then B etc. ASCII, Beowulf, Chimaera, Daedalus, and Excalibur have already been chosen.

An exception to this pattern is unstable, which always has the codename ceres - minor planet number 1 - which is an alias for Debian’s sid.

Devuan suites

Devuan development takes place in suites that indicate a level of stability:

When the current testing moves to stable, the previous stable transitions to oldstable and a snapshot of unstable becomes the new testing.

Codenames or suites?

The release codenames or suite designations in /etc/apt/sources.list indicate which release will be used when updating and upgrading packages. Note that the suite names stable and testing will refer to different releases over time.

As of this writing, stable refers to Devuan Chimaera (Debian Bullseye) and testing refers to Devuan Daedalus (Debian Bookworm). Once Daedalus is officially released, stable will refer to Daedalus and testing will refer to the next release in development, Bookworm (Debian Bookworm).

However, if your Chimaera sources.list refers to the release codename chimaera you will remain on Chimaera until you change your sources.list. That means that you will have more control over when the upgrade happens. And if you are using daedalus in your sources.list you will move seamlessly to the new stable version of Daedalus when it is released.

To avoid the possibility of mixing two potentially incompatible repositories, Devuan recommends using release codenames in sources.list.
