We are pleased to announce the minor release of opam 2.0.6.

This new version contains some small backported fixes and build update:

• Don't remove git cache objects that may be used [#3831 @AltGr]
• Don't include .gitattributes in index.tar.gz [#3873 @dra27]
• Update FAQ uri [#3941 @dra27]
• Lock: add warning in case of missing locked file [#3939 @rjbou]
• Directory tracking: fix cached entries retrieving with precise tracking [#4038 @hannesm]
• Build:
  • Add sanity checks [#3934 @dra27]
  • Build man pages using dune [#3902 ]
  • Add patch and bunzip check for make cold [#4006 @rjbou - fix #3842]
• Shell:
  • fish: add colon for fish manpath [#3886 @rjbou - fix #3878]
• Sandbox:
  • Add dune cache as rw [#4019 @rjbou - fix #4012]
  • Do not fail if $HOME/.ccache is missing [#3957 @mseri]
• opam-devel file: avoid copying extraneous files in opam-devel example [#3999 @maroneze]

As sandbox scripts have been updated, don't forget to run opam init --reinit -ni to update yours.

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

   bash -c "sh <(curl -fsSL https://opam.ocaml.org/install.sh) --version 2.0.6"

   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 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.
