ATBD for heterogeneity, bare soil and Land cover

Hello,

I was looking on the Sen4Cap web page for the ATBD ‘s of the new processors included in SEN4CAP 4.0.
• Bare soil detection
• Parcel heterogeneity
• Change of land cover category

Are they already available? If so, where could I find them?

Thank you very much in advance.

Best regards,

Marta
