Ghost codec news

When was the last news about the Ghost codec? https://people.xiph.org/~xiphmont/demo/ghost/demo.html
"First and foremost, Ghost is vaporware," Montgomery said. "At present it is merely a collection of ideas and some early-stage research. Eventually, it is intended to be a codec that improves upon and supersedes Vorbis in its current niche."

Interesting. I had a few ideas from these in my head for a while without reading about them (in particular, about trying to separate tonal signals and encoding them differently), it's kind of satisfying to see that someone else came up with them too.
But the page you linked seems to be last edited in 2011.

Most part of open source codec developers are involved into development of functional video AV1 encoders like  https://github.com/xiph/rav1e/graphs/contributors
There's work to be done at least for several years (5+ to 10 years) to develop optimized AV1 encoder, VR, 3D and 360ยบ  AV1, AV2 (?) extensions.  And new compression of neural networks and so on.

As for now  AAC family and Opus are considered as more than enough good formats.

This has been discussed here not too long ago. The one area which kinda got overlooked it low-bandwith speech codecs, however the use cases are very different. In particular, those are telephony applications, often use on very band limited cases, such as digital voice radio. Quality is a secondary concern there, the primary being legibility.
