I noticed for quite a while that the (DMD) compilers on run.dlang.io usually aren’t the latest compiler version, neither what’s listed as “dmd”, nor “dmd-beta”, nor “dmd-nightly”; especially the latter ones are really surprising.
Is there a good reason or is run.dlang.io just maintained with low-priority? As far as I know, compiler versions follow a fixed schedule, so updating to the latest main-line version when it comes out could be completely automatic. Nightly could (should?) be updated with every merged PR. I have no idea about dmd-beta, though.
Also, having read LiveView feels faster with a delayed loading indicator, I’d suggest not showing the “progress bar” (which isn’t a display of progress in any shape or form) only after a little while.
