hi gang, i know that the 4.0 preview build is available, but haven’t been able to find any documentation on changes before giving it a shot. is there any documentation/changelog or release timeline available on the new version so i can plan whether to early-adopt the preview build vs continuing with 3.3.0?

hmm. file reference gives a 404. could swear when i looked at this before it was still referencing 3.3.0, but thanks very much for the reference; i’ll track it down in the preview directory on github.
