There are various soft failures in the "GitHub Actions Workflows"

• release_linux.yml:
  • Artifacts are not being uploaded
    • It looks like the path just needs a minor adjustment
      • "No files were found with the provided path: build/linux-ci-release/mapnik-*.deb."
• build_and_test.yml:
  • Every job has failures running mapnik-test-visual
    • I.E.:
      • macOS: "Visual rendering: 109 failed / 4719 passed / 2 overwritten / 6 errors"
      • Windows: "Visual rendering: 116 failed / 4712 passed / 2 overwritten / 6 errors"
      • Ubuntu: "Visual rendering: 114 failed / 4714 passed / 2 overwritten / 6 errors"

Release Linux is not yet finished, I haven't had the time unfortunately.

The visual artifacts are to a degree expected to fail, as the result may differ between the versions of libraries you are using.
