#7828 – Unable to assign atom as a leaving group event if it is eligable
#7806 – Problematic points are not highlighted in red when validation is failed
#7877 – Ketcher losts attachment point name on loading s-group from mol v3000

#7813 – System should not allow to create monomer if atom with many R-groups in the selection
#7815 – System changes right connection point (R2) to left one (R1) if no R1 group defined
#7816 – System swaps left connection point (R2) and right connection point (R1) if R2 group was created early that R1
#7606 – Pasting text into Symbol or Name fields in Monomer Wizard triggers unrelated “Convert error”

Additional notes:¶

Ketcher 3.8.0 has been built and tested with Indigo version 1.36 (standalone and remote).
