opam 2.1.2 • OCaml Changelog

We are pleased to announce the minor release of opam 2.1.2.

This opam release consists of backported fixes, including:

Fallback on dnf if yum does not exist on RHEL-based systems (#4825)
Use --no-depexts in CLI 2.0 mode. This further improves the use of opam 2.1 as a drop-in replacement for opam 2.0 in CI, for example with setup-ocaml in GitHub Actions. (#4908)

Opam installation instructions (unchanged):

From binaries: run
```
bash -c "sh <(curl -fsSL https://opam.ocaml.org/install.sh) --version 2.1.2"
```
or download manually from the GitHub "Releases" page to your PATH. In this case, don't forget to run opam init --reinit -ni to enable sandboxing if you had version 2.0.0~rc manually installed or to update you sandbox script.
From source, using opam:
```
opam update; opam install opam-devel
```
(then copy the opam binary to your PATH as explained, and don't forget to run opam init --reinit -ni to enable sandboxing if you had version 2.0.0~rc manually installed or to update your sandbox script)
From source, manually: see the instructions in the README.

We hope you enjoy this new minor version, and remain open to bug reports and suggestions.
