We just released V13.3 of SEOChecker which we call the Improved Muti culture support release, It is now possible to create redirects that respect the culture.

Besides that we also made sure all pickers support the culture you are targeting in Umbraco

Umbraco allows you to configure domains in so many ways that sometimes the xml sitemaps gave issues in the past so in this release we improved the recognition of domains in a multi culture site to avoid this issue.

Besides all of this we also made sure our property editors return relevant data when used in the Content API and fixed a few bugs.
