Yes, that is the meaning of beta! 😆 We have to make a lot of changes for new features and all kinds of things can break. For constraint order, we did a lot of work on it, but missed that physics weren't sorted correctly (all other constraints are correct). Also we are now much more efficient when sliders have 0 mix (described here), but that change affected many things.
We'll release 4.3.26-beta now and hopefully most issues are fixed. The idea is that we fix things rapidly so fewer users suffer from a single issue. Compare to Adobe or other big companies, where if they have a bug it will be months (or never) that it is fixed, so eventually every user suffers every bug.
Your reports are extremely helpful in finding and fixing bugs quickly. We really appreciate your effort!
