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

This new version contains build update and small fixes:

• Bump src_ext Dune to 1.6.3, allows compilation with OCaml 4.08.0. [#3887 @dra27]
• Support Dune 1.7.0 and later [#3888 @dra27 - fix #3870]
• Bump the ocaml_mccs lib-ext, to include latest changes [#3896 @AltGr]
• Fix cppo detection in configure [#3917 @dra27]
• Read jobs variable from OpamStateConfig [#3916 @dra27]
• Linting:
  • add check upstream option [#3758 @rjbou]
  • add warning for with-test in run-test field [#3765, #3860 @rjbou]
  • fix misleading doc filter warning [#3871 @rjbou]
• Fix typos [#3891 @dra27, @mehdid]

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://opam.ocaml.org/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.

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 you 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.
