Is the project dead and thus not to be relied on going forward?

The reason for the question is the absence of any updates in months and no releases despite some fixes were made since the last release.

Good question and I'm wondering the same thing.

I get the best results from guetzli, so I really hope the project is not dead.

well, at the moment it's only marginally better than mozjpeg (if at all), but orders of magnitude slower, and they both will likely become obsolete by the time an image format based on AV1 is ready (which is probably less than 1-2 years).
so if it was decided to abandon it, I could totally understand the decision.

We have been working mostly on pik -- to incorporate all experience from guetzli and our other efforts into a single algorithm and data format. Pik is similar (according to ssimulacra) or better (according to butteraugli) in compression density to photos with AV1, but simpler and a lot faster to decode.

For my work I have needed to recompres a lot of JPEGs, and I started supporting unofficial fork of guetzli here
