Is this repo active?

As part of Elon's "Full Transparency" thesis, he said that the X algorithm would be 100% open source.

The last commit to this repo is 2 years ago (which is basically when Twitter was purchased). Is it really the case that there has been zero change to the algorithm since Elon took over?

I highly doubt this, and it definitely concerns me given that "transparency" is like his whole MO. Where is the real algorithm code?
