It was mentioned when 4.23 came out explicity that you could achieve Chaos working as experimental if you compile from source. Later in 4.24 no mention and also it was not possible to make it work and it looks the same is going to happen with 4.25.
Could we have an explicit topic mentioning the condition of Chaos for the release at the Release Notes?
There are lots of developers getting frustrated with the engine because the lack of communication regarding this and several hours wasted trying to make it work and all points for it not being ready for public to try, so hardly can be called beta, otherwise it was not have skipped 4.24 already.
