1.0.0

CHANGES:

New Features:

1. Support GitLab CI/CD
2. Support desktop testing on Windows
3. GitHub now uses a composite action rather than a child
   workflow, resulting in less artifact copying and
   quicker builds.

There are significant breaking changes. It will be far easier
to onboard with the new version v1 instructions
and then remove your v0 code, rather than try to do an in-place upgrade:

• Any custom build logic you have in your GitHub workflow should go into
  the new ci/build-test.sh. Alternatively, if you don't care about ever running troubleshooting
  CI on your desktop or GitLab, directly into your new .github/workflows/build-with-dkml.yml.

Breaking changes:

• The GitHub child workflow has been replaced by a GitHub composite action

• Input variables have been renamed to allow the same variable names between GitHub Actions and
  GitLab CI/CD (the latter does not support dashes in variable names).

  Old Name	New Name
  cache-prefix	CACHE_PREFIX
  ocaml-compiler	OCAML_COMPILER
  dkml-compiler	DKML_COMPILER
  conf-dkml-cross-toolchain	CONF_DKML_CROSS_TOOLCHAIN
  diskuv-opam-repository	DISKUV_OPAM_REPOSITORY
  ocaml-options	ocaml_options
  vsstudio-arch	vsstudio_arch
  vsstudio-hostarch	vsstudio_hostarch
  vsstudio-dir	vsstudio_dir
  vsstudio-vcvarsver	vsstudio_vcvarsver
  vsstudio-winsdkver	vsstudio_winsdkver
  vsstudio-msvspreference	vsstudio_msvspreference
  vsstudio-cmakegenerator	vsstudio_cmakegenerator

• Matrix variables have been renamed to allow the same variable names between GitHub Actions and
  GitLab CI/CD (the latter does not support dashes in variable names).

• The shell matrix variable default_shell has been renamed gh_unix_shell

• The operating system matrix variable has been reorganized to distingush GitHub
  from GitLab:

  • os is now gh_os and in use only for GitHub Actions
  • gl_tags and gl_image are the new GitLab CI/CD equivalents. GitLab CI/CD uses tags like
    [shared-windows, windows, windows-1809] to specify the type of runner machine to use,
    and for macOS image you can supply an XCode version like macos-11-xcode-12.
