What's Changed
This release includes several bug fixes and new features. Please be aware Ketcher 2.27.0 has been tested with Indigo version 1.26.0 (standalone and remote).
New features
- #5354 – Apply new hash spacing setting to canvas
- #5579 – Introduce Hand tool for macromolecules mode
- #5590 – Zoom in macromolecules mode should be in relation to the top left corner of the structures
- #5403 – Introduce hydrogen bonds in macromolecules mode
- #5600 – Zoom in automatically upon import of small sequences
- #5637 – Display hydrogen in atom label for molecules in macromolecules mode
- #5556 – Allow import and export of sequences with three letter amino acid codes
- #5640 – Multiple monomers expansion in micro molecules mode
- #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
