GPT5 can write MOO code decently well, but it is usually broken if its asked something complex. The power of it at this point is being able to review code for things like typos, missed comments, or bugs. Super valuable, even if it's not writing whole features. And I wouldn't really want it to. I enjoy coding, and find it relaxing. Having it help with complex problems and maths though, via pseudo code and such, is nice.
Did a full overhaul of the webclient. See details here: Webclient 4.0
This likely is what caused svetlana's issue, and also caused me to be logged in without realizing it once when I woke up my PC from hibernation and it logged me in to the already running webclient instance while I walked away lol.
