• Ubuntu LTS and current release is 22.04 (@dra27 #97)
• When compiling opam, build OCaml once using make compiler on the master
  branch of opam and then share this compiler with the release branches.
  Simultaneously circumvents the sigaltstack problems with OCaml < 4.13 on new
  releases, improves the build time of opam and reduces the carbon footprint of

• Ensure stray double-quotes don't end up in PATH on Windows images (@dra27 #62)

v7.1.0

CHANGES:

• Add ArchLinux support (@kit-ty-kate #23)
• Move Alpine 3.11 to deprecated (@kit-ty-kate #23).
• Add OracleLinux v8 (@kit-ty-kate #24)
• Add Ubuntu 20.10 and Fedora 33 (@avsm)

• Remove outdated bulk-build and archive functions from
  Dockerfile_opam (@avsm)
• Create a Tier 3 for distros for things we do not want
  to test in the opam repository (@avsm @kit-ty-kate)

v7.0.0

CHANGES:

• Do not install opam-installer in images any more. This turns
  out to be a largely optional component as the opam binary
  installer doesn't include it either. It will be made optional
  in the final opam 2.1 release. (@avsm)

• Build multiple versions of opam in the base images. This results
  in an opam-2.0 and opam-2.1 binary being installed, with
  a hardlink to opam <- opam.2.0 so the defaults are unchanged.
  This allows upstream CI images to switch the hardlink to make
  it easier to test newer releases of opam, and also upgrades.

v6.6.1

CHANGES:

• Ensure debconf remains non-interactive (@avsm)
• Do not build ppc64le on Debian:9 as upstream has stopped
  providing images. Debian 10 ppc64le remains unchanged. (@avsm).
