Re: [MirageOS-devel] dns, conduit, cohttp: hit the release train

[Thomas Gazagnaire <thomas@xxxxxxxxxxxxxx>]

I am just cutting a new release of alcotest which will break some packages:

```

```

I haven't reported all the constraints upstream yet, so would make sense to 
double-check them. Also, that would be great to enable `install -t` in the CI 
(or just set OPAMBUILDTEST=1 in the environment) as I spent the week fixing 
test constraints which were pretty broken[1].
