I currently use rhythmbox as my default music player/manager in Ubuntu so it’s with great sadness to hear that there will be no more development on it after it’s 0.12 release.
From the rhythmbox development group came this statement though their mailing list: –
“I hope to be able to make a new release in the next month or so. This will probably be numbered 0.12.0. After that, I'm not planning to do much new development work on the rhythmbox project as it currently exists. I'll still fix (some) bugs and review patches, but it's too much of a dead end for me to do more than that.”
