I looked for any signs of life for the packaging of musescore 4 and couldn’t find any. For that one, you might have to file a Request For Package, which is outlined in the exact link you gave:
5 RFP This is a Request For Package. You have found an interesting piece
of software and would like someone else to maintain it for Debian.
Please submit a package description along with copyright and URL in
such a report.
To do that, file a bug report manually:
- Send to:
submit@bugs.debian.org with a plain-text body.
- Subject line: Clear and descriptive.
- Plain text only: The BTS only accepts plain text email
Use this template:

Description : {short description}
Longer description, lines indented by a single space. Can be multiple
paragraphs.
.
However, paragraphs must be indented by one space and spaces must include
a period as I just did above.
If they don’t get to it by the time 26.10 releases, I might just do it during the 27.04 cycle, but it all depends on how much time I have. Lately, I’ve had bigger fish to fry, and it’s offered as a snap and flatpak, so we do have workarounds if you must have Musescore 4.
As for Audacity, version 4 hasn’t released yet, and Debian will not package pre-released software. With that one, you’re going to have to be patient as it’s out of Debian and Ubuntu’s hands.
I will say, though, that this kind of thing requires patience. Ubuntu and Debian are not exactly in the pace of having the latest software. We want stability, and even if software seems outdated, most of the bugs are fixed by this time.
That said, you’ve only mentioned MuseScore and Audacity, so I have no idea what other software you have in mind that’s outdated as far as you’re concerned.
