Thanks @rjbou ! :slight_smile: For anyone on Ubuntu that wants a quick upgrade, the opam2 PPA has been updated with this release as well.

Thank you for setting up the ppa! It makes it much easier to keep opam updated.

Btw, the opam2 PPA has been advertised a bit here, but I’m not sure its existence is very well known. Would it make sense to advertise it on the opam install page ?

I’m currently having a bit of trouble updating MacPorts to provide opam 2.0.2: see https://github.com/ocaml/opam/issues/3700 If someone can help me figure out that error message, I can probably get MacPorts updated within a few hours.

I’ve made a pull-request https://github.com/ocaml/opam/pull/3701 to update the installation instructions for Ubuntu.

The brew version of 2.0.2 landed today-ish .

It doesn’t build for me with dune-1.6.2 and ocaml-4.07.1: opam-full-2.0.2$ make dune build --profile=release opam-installer.install opam.install File “src_ext/cppo/src/jbuild”, line 10, characters 10-50: 10 | (echo “let cppo_version = “${version:cppo}””))))) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^…

My build error seems to be a dune issue. I pinned/downgrade to dune-1.2.1, and opam-2.0.2 built. Where a package like opam uses dune/jbuilder as its build system and has a specific version dependency, I suggest that the opam release announcement, and preferably also the README, says what it is, so…

Sorry about that @cvine ; this is something we discovered post-release of opam 2.0.2 and is now fixed in Dune master by @rgrinberg and @jeremiedimino : https://github.com/ocaml/dune/pull/1648 The fix will be in the forthcoming dune 1.7.0, and only dune >= 1.5.0 & dune < 1.7.0 should be affected, and …
