We are pleased to announce the minor release of opam 2.1.4, opam-publish 2.2.0 and opam-file-format 2.1.5.

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)

The opam-publish release consists of the following breaking change:

• Shorten the generated branch name. This is breaking change for people who want to force-push changes on an already opened PR using a previous version of opam-publish as the branch name might not be the same (#141)

and the following fixes:

• Fix the github markdown syntax generated by opam-publish (#131)
• Disambiguate GitHub archive URL computed from repository and tag (#135)
• Upgrade to cmdliner >= 1.1.0 (#134)
• Support git remotes with multiple push targets (#137)
• Fix broken state if the initial opam-repository clone fails (#140)

The opam-file-format release consists of the following fixes:

• Fix extra lines on non empty headers (#49)
• Make the tests flambda2-ready (#52)
• Fix build failure on OCaml 5.0 when using the non-dune build mode (#50)

Opam installation instructions (unchanged):

1. From binaries: run

   bash -c "sh <(curl -fsSL https://opam.ocaml.org/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.
