I think the new one remains closed. Sadly, not locked away.

I guess how new are you talking? I think this said it was based on the 2019 release, but I haven’t heard much about recent releases. Winamp 2 was the classic one most people remember. Winamp 3 was a rewrite that was supposed to be better under the hood but a lot of people didn’t like it, mainly for the new interface it seemed. They jumped to Winamp 5 (2+3) to restore much of the old interface while keeping the capabilities of 3. I never had issues with 5 and continued to use it through Windows 7. Haven’t used Windows much since then so I don’t know how it runs now. There have been very rare point updates since AOL took over and later sold it, mostly bugfixes.
