- oxidation numbers can now be displayed automatically. Oxidation numbers are added as textfields and can be moved, formated and changed freely
- when changing the charge of an atom the number of free valences when showing hydrogene atoms should now be calculated correctly
- it should now be easier to edit text fields
- several bugs have been eliminated

several bugs have been eliminated
2.5
2022-08-18
- french translation has been added to MoleculeSketch
- stereochemical bonds improved
- drawing should be a bit more fluid
- other improvements
2.4
2022-01-05
- mol files (with sdf-, mol- and txt-extension) can now be imported. This feature is only available if you purchase the full version (see preferences / three dots).
- the algorithm to calculate free electron pairs and free valences has been should now take hypervaleces into account.
This may cause some changes, if you altered your structure to overcome wrong display of free electron pairs.
- bonds should not cross free electron pairs anymore.
- arrow-bonds should not be clipped anymore.
- under the hood improvements.

Thank you for your feedback, that leads to following changes:
- lone pairs, in conformance with IUPAC rules, can now be represented with dots instead of lines
- bonds are now correctly croped by functional group if the structure is copyed into another program
- new features are listed in the "What's new" section under Help/About
- various bug fixes

- bug fixes concerning the selection and modification of atoms
2.1
2020-04-05
- some functional groups (eg. COOH, Ph, Ts etc.) can now be expanded to full lewis formulas
- C atoms with hidden label are shown as dots when bonds are in line. This behaviour can be controlled in preferences
- various smaller bug fixes
