- new feature added (full version only): you can now mirror parts of a molecule in respect to a selected bond - enhanced compatibility with iPadOS 26 - a bug that prevented moving and editing of oxidation numbers has been fixed - bugs related to inserting atoms and while using a trackpad have been fixed - more shortcuts available when using an external keyboard (full version only) - different bug fixes

- the representation of double and triple bonds has been improved. Double bonds follow now the IUPAC recomondations 2008 for graphical representations of chemical structures - bond line insets can now be manually set in the bond section of the attributes popover (advanced settings) - the old drawing mode for double and triple bond can be switched on or off in preferences for compatibility reasons - a problem that made it impossible to format selected text in text fields when using an external trackpad or mouse has been solved - different bug fixes

- export errors which led to incorrectly croped bonds have been fixed - different bug fixes

- templates for six and five membered rings in Haworth projection have been added - the width of stereo bonds can now be adjusted. If you still wish to use the former style choose the option "calculated" in the attributes or preference panel - an incorretly named nucleic acid was renamed (thank you for pointing it out!) - several bug fixes

- you can now draw rectangles - you can now add a fill color to circles and rectangles - fixed an issue when drawing chains and changing atoms in the chain - small bug fixes

- problems which made it impossible to edit text field editing have been resolved - several bug fixes

- an issue that misplaced hydrogen atoms when exporting as SVG file has been removed - a new file extension type ".moleculesketch" was added for compatibility reasons

Are you using an external keyboard? You can now use keyboard shortcuts to operate MolekuleSketch (iPadOS 16 or above only). Hold the command (cmd) key down to get an overview More information in the what's new section. Otherwise several bug fixes and under the hood improvements

> the color of all selected objects can now be changed at once in the selection popover > the illustration of double bonds has been improved > problems with full version purchase solved > several bug fixes

- SVG export functionality added. Accuracy of exportet svg image may vary depending on the app used to view the exported svg file. - with iPadOS 16.1 or newer: new template gallery with more templates (amino acids, carbohydrates, nucleotides) - a problem, that could have resulted in the loss of added text fields, has been resolved - clipping of stereo bonds reduced - other improvements

- Hot fix for iPadOS versions 16.x: a problem, which made it impossible to open files, has been resolved - spacing between the lines of a double bond can now be changed while editing bonds or in preferences - more bugs have been fixed

- hot fix for iPadOS version prior to 16.1: a problem which made it impossible to open files more than once has been resolved ! -bug with atom symbol positioning has been removed

! The new MoleculeSketch for iPad is here ! - completely renewed user interface (for iPadOS 16.1 or later) - open multiple instances of MoleculeSketch and work with different documents simultaneously using Split Screen or Stage Manager (for iPadOS 16.1 or later) - improved representation of joined stereo bonds - mass calculation now works with deuterium and tritium - several bugs have been eliminated

- 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

- french translation has been added to MoleculeSketch - stereochemical bonds improved - drawing should be a bit more fluid - other improvements

- 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.

A problem that prevented the creation and opening of files has been addressed.

- under the hood improvements

- More option for the alignement of objects - other small improvements

- functional groups that start with a C-atom will not be affected when changing the visibility of CH-groups - free electron pairs now displayed correctly - other improvements

- bugs when copying were resolved

- bug fixes - improvements in drawing speed

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

- R group added to the element chooser - bug fixes concerning the selection and modification of atoms
