opam 2.0.7 release

We are pleased to announce the minor release of opam 2.0.7.

This new version contains backported small fixes:

– Escape Windows paths on manpages [#4129 @AltGr @rjbou]
– Fix opam installer opam file [#4058 @rjbou]
– Fix various warnings [#4132 @rjbou @AltGr – fix #4100]
– Fix dune 2.5.0 promote-install-files duplication [#4132 @rjbou]

Note: To homogenise macOS name on system detection, we decided to keep macos, and convert darwin to macos in opam. For the moment, in order to avoid breaking 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.
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.
