Same 4.2.0 release as the last one but with some small fixes and changes:

• Dropped Python 2.7 support
  • Note that Python 3.5 will enter to EOL later this year, remember to keep your Python version up to date!
• Qt 5 fix for macOS: #293
• MSMF is now disabled in headless builds: #263
• Multibuild updated
• Readme updated

Experimental artifact upload to Azure Blob Storage for every Linux and macOS development build in this repository (Windows build artifacts are available in Appveyor). Uploads for pull requests are not supported. The storage is not free, I pay for it and therefore I might remove the feature or packages from the storage at any point.

To access the artifacts:

1. See the build log output in Travis, there should be something like this in the end:

[
  {
    "Blob": "https://[secure].blob.core.windows.net/2fd09dc0c3872f496d4c294b20de7c35ef75c39b/opencv_python-4.2.0+2fd09dc-cp35-cp35m-manylinux1_x86_64.whl",
    "Last Modified": "2020-03-21T15:39:55+00:00",
    "Type": null,
    "eTag": "\"0x8D7CDAE1AFDA647\""
  }
]

• you could also use the commit hash & other info to construct the download URL

2. Replace the [secure] part in the link with opencvpythonartifacts
   • the link structure is https://opencvpythonartifacts.blob.core.windows.net/[build_commit_hash]/wheel_file_name.whl
3. Download the artifact for example via a browser
