  • #5187 – Introduce new amino-acid colors

  • #6174 – Update indigo to 1.26.0 in browser module

Bugfixes and improvements

  • #5370 – System should remember the canvas mode on Molecules/Macromolecules mode switch (do not switch to Sequernce by default)

  • #5372 – Toggling between Flex and Sequence modes causes loosing layout info

  • #5564 – Search of ambiguous monomers doesn’t work

  • #4475 – Numbers on top of letters are not centered

  • #4936 – Applying Enhanced Stereochemistry to monomers causes its disappear from the canvas (and exception in console)

  • #4941 – System shows Edit S-Group option for every bond of molecule if it has attachment point

  • #5181 – getKet duplicates items when macro molecules are use

  • #5398 – Elliptic arrow icons order is wrong at arrow toolbar

  • #5935 – Unable to establish hydrogen bond connection if monomer has no free attachment points

  • #5941 – Hydrogen bonds remain in place on monomer delete

  • #5940 – Copy/paste operation works wrong (copy only two hydrogen bonds and drops others)

  • #5933 – Error message is wrong if user tries to establish hydrogen bond if it is already exist

  • #5967 – System should not change monomer position after switching from Molecules to Macromolecules - Sequence

  • #5972 – Export to three letter amino acid codes cause convert error

  • #5969 – Load from file having only micro structures on macro canvas causes unnecessary zoom up to 200% and shift molecule to top left angle

  • #5970 – Unable to connect monomer to molecule in snake mode

  • #5949 – Delete of micro molecules bonds works wrong (or doesn’t work)

  • #5910 – Fix closest sgroup detection to allow focusing on entities within expanded monomer’s bounding box
