Summary

This release adds several new BiDi options and API enhancements, fixes numerous bugs, deprecates Java FtpProxy, and introduces a breaking namespace change in the .NET bindings.

⚠️ Breaking Changes

  • dotnet: Simplified modules namespace for end users, requiring updated import paths for Selenium .NET BiDi classes. Update your using statements to the new namespace.

Migration Steps

  1. Update .NET import statements to the new simplified namespace as per the breaking change.
  2. Replace any usage of the hard-coded capability string "se:downloadsEnabled" with CapabilityType.ENABLE_DOWNLOADS.
  3. Avoid using the deprecated java FtpProxy class; switch to the recommended proxy configuration.
  4. If using the removed stylecop files in .NET projects, delete them.
