Dear everyone,

as you may have seen I'm involved in a project to push opam packages out of the main opam-repository to improve the performance for everyone (read more at https://discuss.ocaml.org/t/proposed-package-archiving-policy-for-the-opam-repository/).

Now, we're getting closer to "Phase 3" - which means that packages marked by maintainers with "x-maintenance-intent: ..." can be archived. Since this is opt-in, I'm keen to have as many opam packages specify this extra field as possible.

Turning at the MirageOS GitHub organization and the mirage project itself, I'm curious whether anyone has reservations against stating "only the latest version is supported". So, is anyone keen to retain and maintain earlier versions (if yes, please indicate why and for which packages).

If there's no objection, I'll push forward with the above for the mirage-related packages (I won't touch those big packages used elsewhere, but only provide issues and/or pull requests for things like cohttp, irmin, uri, capnp-rpc, alcotest, cow, ..). I'm more into packages such as mirage, tcpip, mirage-net, mirage-net-xen, ... and put a 'x-maintenance-intent: [ "(latest)" ]' from next week on unless someone stops me.

Another related question is about packages that are no longer maintained, I already marked some of these with "flags: deprecated" in the main opam-repository.

It helps if everyone who authored and/or maintains packages to push these fields into the opam-repository and the opam files in the repositories.

Two notes about that: only the latest release of a package needs to have the "x-maintenance-intent" field. And, if there's a reverse dependency on an earlier version (that won't fall under the maintenance intent), this version will be kept. We don't want to introduce package installation failures due to missing dependencies.

If you're interested, take a look at the field specification https://github.com/ocaml/opam-repository/blob/master/governance/policies/archiving.md#specification-of-the-x--fields-used-in-the-archiving-process

And follow the opam-repository tag on discuss: https://discuss.ocaml.org/tag/opam-repository

As said above, I'll push forward with the mirage packages starting next week unless someone has objections.


Best,

Hannes
