Set Plot Size Dialog
- Added Portrait and Landscape settings to this dialog to provide another location to change the orientation.

Formula Entry Window
- Now supports multiple lines in the main section of the window, using the same syntax as multi-line formulas in the Posted Note. Because of this change, the Enter key on the numeric keypad is now the only keyboard shortcut to execute the formula.
- It is now possible to run multi-line formulas and formula scripts without closing the Posted Note.
- If a syntax error is detected, the error dialog will display a portion of the function that caused the error.
- When Formula Entry is the active window, typing the F1-F9 function keys on the keyboard will activate the various function buttons. F9 activates the Posted Note window.
- The table() function can now be used on data columns that have masked or missing values.

Edit String Dialog
- The menus were replaced by graphical controls.
- Added support for overline and strikethrough font styles.
- Added the ability to resize the dialog.
- Editing functions are available via keyboard shortcuts and the shortcut menu.
- Added support for multiple undos, but not through the History window.

Interface Changes
- Changed the default data type from Float to Double.

- As you drag to make a selection in the data window, the coordinates in the lower-left corner update to show the current location as you drag.
- The Posted Note now appears as a panel in the data window instead of being displayed as a separate dialog. Printing and editing commands are available from the File and Edit menus when the Posted Note panel is the active section.
- The various text editors temporarily replace the original window instead of being displayed as an additional dialog. All of the editors contain Open and Save As buttons and an option to show the row numbers. The editors for the Posted Note and Edit Program support normal printing and editing commands via the File and Edit menus. The other editors provide a Print button while normal editing commands are supported via keyboard shortcuts and right-clicking within the dialog. The editors also support multiple undos, but not through the History window.
- If a file gets edited, it is noted by a black dot in the Close box (Mac) or a * behind the name (Windows).
- Due to adding support for Unicode, typing a Latin character in the Edit String dialog on the Mac and converting it to the Symbol font will not immediately display the Greek character. It will be displayed when you exit the dialog. It is possible to see the character immediately if you copy it from the Font Book application and paste it into the Edit String dialog.

- Added a Select All button to the Curve Fit Selections dialog.
- The plot tools are no longer on a floating palette and are now part of the plot and layout window.
- The total number of fill patterns available has increased to 24, which includes 8 gradient patterns, and are identical for both platforms. Because the fill patterns have changed, you may see some of the patterns change when opening older plots.
- Added more options for changing the magnification level for the plot and layout windows.
- Up and down arrow buttons were added to the Variable Selection dialog to change the order of selected plot groups.
- Names of hidden windows are no longer displayed in italic. Names of hidden windows now show two dashes before the name in the Show Data and Show Plot submenus.
