The Debian Project continues to work on the unstable
distribution (codenamed sid, after the evil and
"unstable" kid next door from the Toy Story 1 who
should never be let out into the world). Sid is the permanent name for the
unstable distribution and is always 'Still In Development'. Most new or
updated packages are uploaded into this distribution.
The testing release is intended to become the next
stable release and is currently (as of July 2024) codenamed
Trixie.
