There was a problem hiding this comment.
I think it's clear from the name of the config or this description what this feature did. It makes it sound like dev tools are not really supported at all without this feature. But that's not true. So I think, if this is to be included, we have to be more precise:

| <li><var>"DUNE_CONFIG__LOCK_DEV_TOOL"</var>" is not enabled anymore but can still be set in the environment. This features makes dev tools automatically installed when they are invoked. E.g., running "<code>dune fmt</code>` will automatically install `ocamlformat`. Without this feature, one simply has to run `dune tools install ocamlformat` first. To use and install dev tools run "<code>"dune tools"</code>" "</li> |

I think it might be nice for continuity to explain to people why, when they go to
preview.dune.buildthey get the nightly. So I added an entry to the FAQ.Feel free to close it if we decide to just drop the preview branding altogether, to avoid any possible confusion.
