opam 2.1.4

Feedback on this post is welcomed on Discuss!

We are pleased to announce the minor release of opam 2.1.4.

This opam release consists of backported fixes:

  • Make opam able to fully build with OCaml 5.0. dose3 >= 6.1 and base64 >= 3.1.0 are now required (#5357)
  • Fix a bug where opam would not output any explanation when a conflict arises when attempting to install a package (#5378)

Opam installation instructions (unchanged):

  1. From binaries: run

    bash -c "sh <(curl -fsSL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh) --version 2.1.4"

    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.

  2. 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)

  3. 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.
