Additions

1. New advanced methods for creating, setting, and altering chemical document settings and formats. Bond preferences have been redone with many more options and are all 100% accurate. Preferences are now document dependent and will be retained when saved or when switching between tabs. Font and sheet size are now saved with preferences. To find out more, click here.
2. Added many chemical document formats including: ACS Document 1996, Helvetica Chimica Acta, RSC (1 and 2 Columns), and many others.
3. Doodle Sheets can now be resized.
4. Added more template packs: Cycloalkanes, Functional Groups, Hexoses, Polycycles, Stereocenters and more Ring Conformers. A separator now appears between official and unofficial template packs.
5. Drag and drop has now been implemented. To find out more, click here.
6. Radicals have been fixed, and are now separate from charge decorations. Radical properties can be changed in the Preferences menu, and radicals now automatically orient themselves according to the angle from the parent atom.
7. New advanced affine transforms have been included. The added arbitrary rotate and advanced scaling functions are precise and intuitive. To find out more, click here.
8. New menu items have been added including (not mentioned elsewhere): Clear, Purge History, Close and Close Others.
9. Dragging slightly outside of the Doodle Sheet will cause the scroll bars to scroll, if appropriate.
10. Added circular atom guides in the View menu that draw circular guides around atoms with a radius equal to the bond length.
11. Base64 encoding is now used to embed images in ChemDoodle Documents. This allows for larger files to be embedded, and therefore the size restriction has been removed.
12. Widget buttons now display tool tips.
13. Added a new Purchase menu for easy access to the Permanently Activate ChemDoodle menu item. This menu disappears after ChemDoodle is permanently activated.
14. Added a new filetype and icon for ChemDoodle Chemical Document Settings Files (.cds).

Fixes

1. Sliders in Preferences now contain a number field, and the units can be changed.
2. Fixed bug where scale edges in the Multiplet Widget were incorrectly calculated when a simulation was showing.
3. SMILES Widget now displays an appropriate message when empty content is input.
4. MolGrabber LITE Widget and SMILES Widget lists have been improved for easier reading.
5. Template Widget no longer loses focus when traversing template lists.
6. Symbols Widget now works with label objects.
7. Label objects can now be edited by double-clicking on them.
8. Shift now properly locks the aspect ratio for all shapes when resizing or placing, except for lines. Lines will align vertically or horizontally when shift is held. Shift now causes the screen to update for immediate feedback.
9. Fixed problem where rounding errors would occur when editing objects at scales other than 100%.
10. Fixed small bug where the cyclopropane button actually places cyclobutanes.
11. Cut/copy/paste and undo/redo buttons and menu items have been overhauled so that they remain consistent. Paste now always appears in the right-click menu if there is something to paste. Images can be directly copied to the clipboard. Undoing the "New Doodle Sheet" item in the History widget no longer removes it.
12. Radicals now appear properly.
13. Fixed problem where HTML areas were not being properly read from save files.
14. Fixed problem when saving transparent images, where the transparent property was not being set.
15. Fixed problem where documents beginning with "Untitled" could be duplicated in the system.
16. The appropriate tab will be selected when prompted to save a file that is not the currently selected tab.
17. Fixed problem where closing a tab also closed the tab to its right.
18. Fixed problem where Unacceptable Oxidation State warnings lingered even after they were addressed.
19. Fixed message that was displayed when checking for updates could not continue because ChemDoodle could not connect to the internet. Added a timeout to URL connections. Improved internet connection errors.

21. Splash screen now notes when OpenBabel is queried.
22. Template menu items no longer appear if shapes are selected.
