We are pleased to announce the minor release of opam 2.0.5.

This new version contains build update and small fixes:

Note: To homogenise macOS name on system detection, we decided to keep macos, and convert darwin to macos in opam. For the moment, to not break jobs & CIs, we keep uploading darwin & macos binaries, but from the 2.1.0 release, only macos ones will be kept.

Installation instructions (unchanged):

  1. From binaries: run 
sh <(curl -sL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh)

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.

  1. 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 you sandbox script)

  1. 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.
