CI/CD Spam in Plugin Directory

[soup-bowl]

You may notice there's 3 unexpected new files in the wp-simple-smtp directory:

• DOCKER_ENV
• docker_tag
• output.log

These files were unfortunately introduced during the deployment pipeline, and have subsequently been packaged into the release file. I've since added these to the exclusion list, so in later deployments they won't be present.

Until next release, you can delete these files without detrimental effect. Next update should remove these anyway.

Now referenced in the readme.md.
