Feedback on this post is welcomed on Discuss!

We are pleased to announce the patch release of opam 2.1.6.

This opam release consists of backported bug fixes and improvements:

  • Changes necessary for opam-repository (see ocaml/opam-repository#23789)
    • Warn if GNU patch is not detected when a patch is applied (#5893)
    • Use gpatch by default instead of patch on NetBSD and DragonFlyBSD (#5893)
    • Use gpatch if it exists and is detected as GNU patch when patch is not GNU patch (#5893)
  • Better recognize depexts on Gentoo, NetBSD, OpenBSD (#5065)
  • Upgrade the vendored dune to 3.14.0 (#5869)
  • Fix debug logs showing up regardless of verbosity on macOS 12.7.1 / 13.6.3 / 14.2 and FreeBSD (#5769)

Opam installation instructions (unchanged):

  1. From binaries: run

    bash -c "sh <(curl -fsSL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh) --version 2.1.6"

    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.
