This is a bugfix update fixing some issues brought to our attention. This update introduces a much more powerful EXE build for Windows, and addresses stability issues related to using grouped objects.
- A new EXE is built for Windows. This EXE will now use either the 64 bit or 32 bit JRE if available. If both are available, the new executable defaults to the 64 bit JRE.
- iChemLabs Updater has been updated to work in mixed Java environments on Mac OS X. Those with both Java 1.7 and 1.6 installed on Mac OS X will notice that ChemDoodle will not automatically open after the update. Ignore this, as this new updater corrects this issue.
- Fixed IUPAC naming issue where locants were not correct in ring blocks for stereocenters.
- Fixed IUPAC naming where a double dash could occur.
- Fixed bug where groups would not always resize all their contents.
- Fixed crash if non-recognized colors were present in ChemDoodle Documents.
- Colors in groups and reaction area text are now stored correctly in ChemDoodle Documents.
- Limited the size of files previewed by the Quicklook plugin to 200MB.

- New arrow types:
- A new function to select by SMARTS. ChemDoodle now has a full implementation of the SMARTS matching protocol; further features that access this functionality will be provided as ChemDoodle evolves.
- A new SMILES option to preseve bond orders on output. In essense, aromaticity will not be output to SMILES.
- The ChemDoodle workspace now sizes appropriately. On smaller screens, ChemDoodle will still expand to the full view, but on larger devices, ChemDoodle will only take as much room as necessary. When resizing the workspace, the widgets will be appropriately placed to the right of the window. The workspace size and location are now preserved between sessions.
- A new Kekulize function that assigns double bonds to sets of bonds to maximize pi electron delocalization. If a structure consists of only single bonds, this function will affect the entire structure. If a structure has any resonance bonds assigned, only those bonds will be affected. SMILES input now automatically Kekulizes input.
- Text area font colors can now be changed.
- Designating all resonance bonds in a ring now forces that ring to be defined as aromatic.
- New keyboard shortcuts to add rings to bonds using the shift key. Alternate bond types are now assigned using the alt key.

July 30, 2010
ChemDoodle 3.2 is a significant update containing major new features and improvements. Notable features include orbital objects, the expansion of condensed formulas in atom labels (allowing for the automatic proper handling of condensed formulas by the Properties widget and other algorithms), a more robust abbreviations system (that can be used in atom labels for all atom models) and integration with the ChemSpider database. Notable improvements include an evolution of the ChemDoodle rendering engine for improved rendering and performance as well as full control over the low level graphics settings, a new table layout for the Properties widget that conveniently updates when drawing a single molecule, and full compatibility to directly paste scalable vector graphics into the entire Microsoft Office suite on Windows and Mac OS X.
- Orbitals can now be added to structures. These are 2D graphics that can be attached to atoms or bonds or can be standalone. A gradient is used to give them a 3D appeal. Supported are atomic orbitals (s, p, d, f), hybrid orbitals (sp lobe, sp3), and bonding orbitals (σ, π). Orbitals can also be read from and written to ChemDraw files. There are two visual specifications for orbitals in the Preferences window under the Visuals tab under the Shapes subtab: Length Multiplier – Sets the default size of orbitals relative to the current bond length; Stroke Shaded Lobes – Sets whether or not outlines are drawn around shaded orbital lobes.
- The graphics engine in ChemDoodle has seen a significant upgrade and graphics rendering has significantly improved. Performance has also been significantly improved. Graphics controls for low level rendering are now exposed in the Preferences window under the Advanced tab. Change these only if necessary to favor speed or to affect how graphics are rendered. These rendering options will only affect devices with resolutions, such as bitmap images and monitors; scalable vector graphics remain perfect and unchanged.
- Added a new option to simulate soft clipping for bitmap images in the Advanced tab of the Preferences window. This makes Recessed bonds look much nicer.
- A new system for expanding condensed formulas and abbreviations in atom labels to their all atom models. There are several features that benefit from this:
- All calculations based on structures (properties, NMR spectra, etc.) will first expand the molecule, so proper results will now be obtained when using condensed formulas.
- Atom label errors are improved. ChemDoodle will alert you of unknown tokens and will properly evaluate atom valencies. For instance, a terminal label of CH3 will be approved while a terminal label of CH4 will not.
- Abbreviations can now be expanded. So Ph, Et, COOH, etc. will be properly expanded to the corresponding all atom models and can be used in condensed formulas. You can add your own custom abbreviations.
- Atom label token stacking is more intelligent and will now stack based on token groups. For instance, the label CH2CH2COOCH2CN will stack as (CH2)(CH2)(COO)(CH2)(CN).
- Complex shorthand notations are also supported, so C(CH3)3 will be expanded as a t-butyl fragment and CPh3 will be expanded as a triphenylmethyl fragment.
- The ChemSpider database has been integrated into the MolGrabber widget.
- The Properties widget now has a second mode that will be automatically activated when a single molecule, and only a single molecule, is being edited in the current document. The display will change to a table that will list the most important properties and will automatically update if allowed. There is a new checkbox at the top of the widget to disable automatic updating of the data, which will be useful for less powerful computers.
- Scalable vector graphics can now be directly pasted into the entire Microsoft Office suite, including Powerpoint and Excel.
- Added a Save Selection as Image… menu item to the File menu to quickly save just the selected content to an image.
- Added a Copy As submenu to the Edit menu to quickly copy selected structures as various datatypes at maximum compatibility on the system clipboard.
- Added a new drag erase gesture when using the Eraser tool. Press and drag over any objects to be removed and they will be highlighted. Release the mouse to delete all highlighted objects. If you drag over a previously highlighted object, it will be unhighlighted.
- ChemDoodle Web Components v3.1 is now included. The ChemDoodle Web Component generator has been updated accordingly. New default sizes are provided for standard iOS device resolutions.
- Molar Refractivity can now be calculated for structures.
- Some widget settings are now saved in the workspace, including the last selected widget and the database choice in the MolGrabber widget.
- The MolGrabber widget now provides a direct link to the chosen database’s website for the selected molecule. Press the Show Associated Data button and the top item will show the database’s compound id. Click on the compound id to visit the webpage for that molecule.
- Menu items for unrepresented keyboard shortcuts have been added: Flip Bond, Align Bond and Add Attribute.
- A new keyboard shortcut for adding attributes to hovered objects, Shift-A.
- Added a new visual specification to set whether the second bond line in double lined bonds are shrunken when next to an atom label.
- Radial gradient rendering is greatly improved for shapes to better portray 3D appeal.
- Improved how the default style sheet is saved. The default style sheet will no longer be affected when ChemDoodle is closed. Both changing preferences and conforming a document will now ask if the new settings should be default. A new menu item, Save Document Settings…, is present in the Window menu for explicit saving the current document style sheet as the default settings.
- Fixed a bug where structures could not be dragged into the Line Notation Pad widget.
- Fixed bug where changing tabs when content was selected would change the colors of the selected content.
- Selected content is now properly remembered when switching between tabs.
- Fixed issue where a molecule still appeared selected if it was deselected using the alt+shift keyboard shortcut.

- Colored in ring guides no longer appear in output.
- Fixed bug where an infinite loop started when cleaning complex multi-ring-substituted ring systems.
- Fixed bug where some structures were not being cleaned.
- Improved the cleaning of complex ring systems.
- When cleaning structures, triple bonds are now aligned parallel to their substituents.
- Improved boundary conditions for token alignment to favor the horizontal alignments.
- Fixed bug where some counters were not being calculated in the Properties widget.
- The Calligraphy stroke skew angle has been offset by 15 degrees to avoid ghosting effects with vertical bonds.
- The arrow size for the ACS Document 1996 chemical document settings has been set to 8 pixels by default.
- Changing the arrow specifications now will apply to arrows without having to reselect an arrow tool.
- ISIS Sketch files that are missing the closing tag are now read properly.

December 19, 2008
This release contains full access to the PubChem database, stereochemistry functions, new identifier objects, 3D functions, an enhanced menu system, improved widget controls, new object properties, and much more. Please refer to the complete list below for details.
- The MolGrabber widget has been completely redone and now contains a full and direct connection to PubChem. You may now search through a database of over 20 million predrawn structures to use in your documents. The ability to handle large numbers of results has also been improved. Properties from PubChem can also be displayed with the new Show Associated Data button. All work is now multi-threaded for excellent performance while a spinner keeps you updated of the progress. You may read more about this feature here.
- Stereochemistry can now be discovered and assigned. These functions are accessable in the new Structure menu and in the right-click menu after lassoing structures. You may search structures for chiral carbons and assign CIP R/S identifiers to them. You may also search structures for asymmetrical double bonds and assign CIP E/Z or cis/trans identifiers to them. You can also force stereochemistry on potential and assigned stereocenters. You may read more about this feature here. All stereochemistry objects have been included in our CDX/CDXML interpreters.
- New objects called Identifiers can now be associated with objects. Identifiers are both logically and spatially associated to an object so that they can be moved only within a certain radius of the object they describe. You may add bulk identifiers with some of the chemical functions provided in ChemDoodle. You may also add individual identifiers by right-clicking on an object and selecting the Add Identifier menu item. Each identifier has display content and a name. A name should be unique to a group of identifiers so you may use more advanced queries and functions later. The identifier binding distance can be changed in the Preferences window under the Visuals tab. You may read more about this feature here.
- 3D coordinates for structures are now supported. There is a new button in the Functions toolbar for allowing you to rotate structures in three dimensions. ChemDoodle will read and write 3D coordinates to all chemical filetypes. You may read more about this feature here.
- Bond angles and bond lengths can now be separately locked. The shift key toggles bond length locking, while the alt key toggles bond angle locking. The Preferences window contains options for the default behavior for adding bonds. You may read more about this feature here.
- The alt key, when held, will allow you to select an entire molecule in select-one mode when a constituent atom is clicked. It can be used in conjunction with the shift key to add and remove entire molecules from the lasso.
- Menu System:
- The menu system has been dramatically improved. There are two new menus, Content and Structure. The Options menu has been removed and its functions redistributed. The Content menu contains functions for manipulating objects on the Doodle Sheet while the Structure menu contains chemical functions.
- A new Convert menu item has been included for converting chemical files between the formats recognized by ChemDoodle. (File)
- A new Actual Size function for negating zoom effects. (View)
- A new Current Selection function for centering the currently selected objects in the view of the Doodle Board. (View)
- Added a new Doodle Sheet guide to specify the boundaries of the page margins. (View)
- There are new functions for aligning and distributing objects on the page. The distribution functions can also be done with more precision by specifying certain parameters if you choose to supply them. (Content)
- There are new functions for selecting objects on the page. You may select the previously lassoed objects, the next molecule, or the inverse of the currently lassoed objects. (Content)
- New Deselect and Reselect menu items. (Content)
- A new Join function for combining two atoms into one. (Content)
- New Add Frame functions for surrounding the currently selected objects with various frames. (Content)
- The Add Hydrogens function can now be applied to specifically lassoed structures or to the entire contents of the Doodle Sheet. (Structure)
- The Generate SMILES String function of the right-click menu is now mirrored in the Structure menu. (Structure)
- The Add Abbreviation function of the right-click menu is now mirrored in the Structure menu. (Structure)
- Object Properties:
- Atoms, bonds and identifiers now have their own formatting window, just like shapes. You may access this window in the right-click menu or by double-clicking on the object.
- Atoms and bonds now contain their own set of properties, so they do not need to match the currently assigned chemical document settings. When an object is first placed, it will inherit all of the properties of the currently assigned chemical document settings. You may then alter the object’s properties by right-clicking on it and then selecting the Format Object menu item.
- There is a new button located in the Functions toolbar that will conform lassoed objects to the currently selected chemical document settings.
- There is now a new Atom Label Buffer property in the Preferences window under the Visuals tab. This buffer controls how closely bonds will draw to an atom’s text.
- There is now a new bond Overlap Buffer Space property in the Preferences window under the Visuals tab. This buffer controls how much whitespace will be “erased” from bonds located underneath other bonds. This property can also be disabled.
- Added a new Double Bond Asymmetry option to allow double bonds to be rendered off-center if that bond connects two Carbons.
- ChemDoodle Documents now save the Ignore Warnings property of atoms. Object warnings can be rechecked again if you select the new right-click menu item, Check for Warnings.
- All compatible properties have been included in our CDX/CDXML interpreters.
- The XYZ format can now be read and written. Several options are included for this format, such as which atom identifier to use and whether to buffer this identifier. These options can be specified in the Preferences window under the Saving tab.
- SVG and Adobe PDF graphics can now be displayed so you may add vector graphics to your figures.
- Added a new Snap to Grid option in the Preferences window. You can snap to either a 5 pixel or 10 pixel grid (or none, of course).
- Widgets are now resizable. The maximize button will now expand the widget to the largest practical size, or reduce it and replace it to its starting position and size. Windows and Linux frame icons have been changed to more naturally match their native look and feel.
- Specific image types can now be placed onto and retrieved from the System Clipboard in addition to the generic java image. These types include png, gif, jpg, ppm, tiff and bmp. The only ones pasted by default are the generic java image and bmp (for OpenOffice compatibility). You may change these options in the Preferences window under the Advanced tab.
- When conforming objects to chemical document settings, you will now be asked if you would like to change the fonts of the objects along with being asked if you would like to scale them.
- When zooming in and out, the currently lassoed objects will be centered in the view of the Doodle Board. If no objects are lassoed, all objects will be centered in the view of the Doodle Board.
- If either of the affine transformation tools or the lasso tools are selected, the last object or structure added to the Doodle Sheet will be selected. If you double-click on the Doodle Sheet in the 2D affine transformation mode, the lasso will now be emptied.
- Templates now auto-connect to nearby atoms just like rings do. Auto-connect can now be disabled in the Preferences window under the General tab.
- XML file parsing errors are now displayed in an error message pane when trying to load XML chemical filetypes.
- Added more greek symbols to the Symbols widget. Increased the size of the symbol preview box. Elements will now also display a preview.
