• Made some changes addressing a bug that occasionally caused the program to crash when editing a text label.

• The application is now much more responsive when dealing with complex graphs.
• Data importing now interprets parenthesized numbers like "(45.2)" as "-45.2". It also now handles negative currency values, such as "-$45.20".
• Points whose type is "none" (ø) are now never drawn. Standalone "none" points in older graphs will be converted to a "circle" shape to ensure that they look the same as they did before.
• Rectangular select mode now finds all graph elements that intersect with the selection rectangle. Hold down the option key to only select items that are fully enclosed by the selection rectangle.
• Point clusters now stay locked in place if any of the individual points in the cluster are locked.
• Improved the appearance of selected objects. The selection ring now uses the color specified in System Preferences.
• The OmniGraphSketcher help pages (accessible from the Help menu) are now complete.
• Status bar messages are more consistent and useful.
• Added tooltips to all of the inspector controls.
• Improved the positioning of application windows when OGS is launched for the first time.
• Fixed a bug that sometimes caused OGS to crash when drawing fills bounded by curved lines.
• Fixed a bug where deleting a line endpoint would occasionally cause additional lines to be deleted.
• Fixed a bug where grouped items would sometimes forget their group after undo-redo sequences.
• Fixed a bug that caused some legacy files from Robin Stewart Software Graph Sketcher to not be upgraded successfully.
• Adjusted the trial period to 14 days.
• Smaller fixes and improvements.

• Quick Look previews now work. (OGS files created before beta 5 need to be re-saved to get this feature.)
• Spotlight indexing now works, so you can find graph files whose text labels contain your search terms. (OGS files created before beta 4 need to be re-saved to get this feature.)
• Quick Look and Spotlight are also now enabled for ".graph" files created with Robin Stewart Software Graph Sketcher.
• Added a menu command called "Make Current Styles Default" which saves your current fonts and axis visibility settings as defaults for future graphs. We plan to replace this with full-featured graph templates in the future.
• Now the "Connect Points" button on the data inspector connects points in the order they appear in the list, rather than from left to right.
• Documents in progress now get autosaved and are reopened automatically after a crash.
• Smaller fixes and improvements.

• Objects snapped to an intersection now stay at the intersection even when its location changes.
• Added new toolbar buttons: Detach, Show/Hide Grid, and Scale to Fit.
• Improved point snapping and detaching. Now when you snap points together, they will always move around together until you use the "Detach" command (which now works reliably). Detach also applies to un-snapping points from lines and labels.
• Improved the way the graph scales to fit data. Now the axis ranges will only change if you import data that falls off the current graph, or if you click the "Scale to Fit" toolbar button or menu command.
• Improved data importing:
• Data import can now handle quoted values in comma or tab separated files.
• Data import can now ignore all currency symbols.
• When using the data inspector, new points don't get created until you enter a value for both x and y.
• Changed the behavior of the shift and command keys to be more consistent with other applications. With the shift key, you can now select a whole range of related objects, such as points on a line or tick labels on an axis. The command key lets you selectively add and remove objects from the selection.
• Points shaped as tick marks are now displayed at a jaunty angle when not attached to a line or axis.
• When you move the cursor close to an axis tick label, you can now select all tick labels on the axis.
• The color panel now works when opened from the toolbar as well as from the inspector.
• The "Revert" menu command now works as expected.
• Fixed several bugs related to copying and pasting connected lines, fills, tick-mark shaped points, and grouped objects.
• Fixed a bug where text pasted directly into a label could cause the label to behave strangely.
• Fixed a bug where axis tick labels could be temporarily dragged away from the axis.
• Fixed a bug where the left margin would not be wide enough under certain circumstances.
• Fixed a bug where occasionally a tick mark would be printed underneath the arrow at the end of an axis.
• Made the calculation of tick mark spacing more consistent.
• Improved undo/redo for text labels, bars, line segments, best-fit lines, axis components, and margins.
• Improved application performance and reduced memory footprint, especially while importing larger data sets.
• Files are now compressed when saved, using significantly less disk space.
• Many smaller fixes and improvements.

• Fixed a bug that gave error messages when filling in certain types of areas.
• Fixed a bug where a label attached to a point could act as though it was still attached even after the point was deleted.
• Gave best-fit lines the ability to be vertical (when all points have the same x-value).
• Improved ability to open invalid files.
• Adjusted all of the inspector layouts.

• See the OmniGraphSketcher product page for a new screencast on importing data.
• Improved the "Getting Started" graph that appears the first time you launch OmniGraphSketcher.
• Updated the colors used when importing data series.
• Fixed a bug that sometimes caused text labels to lose focus when typing with the text tool.
• Fixed a bug that caused some graphs with best-fit lines to crash when closing.
• Fixed a bug where very short lines with arrowheads could cause a hang.
• Changed the "line type" option on the inspector so that it no longer creates a line if there is nothing selected.
