1.2.0

• Improved progressive rendering logic, reducing wait before seeing first results in viewer
• Geometry cache is now limited to ~1GB per open document instead of being unbounded
• Cached geometry is now cleared when document is closed instead of persisting for app lifetime
• Invalid font names now produce an error instead of silently falling back to Helvetica
• Paths are now drawn in white when background is set to a dark color or texture
• Fixed an index out-of-bounds crash in the Levenshtein distance function
• Bumped Euclid to 0.5.8, which includes several bug fixes
• Renamed GeometryType.none to the more descriptive GeometryType.group
• Made Geometry.mesh and Geometry.associatedData properties thread-safe using NSLock
• Removed Scene.deepCopy() and Geometry.deepCopy() methods as instances are now thread-safe
• Moved selection logic out of ShapeScriptLib and into Viewer example application
• Fixed bug in Viewer where geometries would be deselected during progressive loading
• Added LRUCache dependency

1.1.6

• Paths are now drawn using polygons strips, which looks sharper and renders more consistently
• Made further improvements to cancelling in-progress rendering when reloading a file
• Bumped Euclid to 0.5.4, which includes several bug fixes and performance improvements
• Improved performance when rendering scenes with nested CSG operations or groups
• Fixed rendering and bounds calculation of non-planar extruded shapes

1.1.5

• Info window in ShapeScript Viewer no longer included imported models in texture count
• Fixed a regression in ShapeScript Viewer 1.1.4 where error message wouldn't refresh correctly on reload
• Improved error messaging for errors that occur in an imported file
• Reloading a partially-rendered scene should now terminate the rendering more quickly, freeing up CPU
• Rendering is now cancelled when document is closed (previously it continued in background)
• Improved responsiveness of incremental rendering for complex scenes
• Program source and statements properties are now public

1.1.4

• Increased time precision of document file monitoring in ShapeScript Viewer app
• Improved threading a progress logging in ShapeScript Viewer app

1.1.3

• Fixed assertion failure if a parsing error occurs at the last character in the .shape file
• Fixed bug in Path plane calculation that could result in corrupted extrusion shapes
• Fixed a tessellation bug affecting anti-clockwise polygons

1.1.2

• Fixed bug where CRLF was treated as two separate linebreaks, resulting in a crash
• Error column indicator is now better aligned when code contains wide characters (e.g. emoji)
• Fixed inverted black/white squares on chessboard example

1.1.1

• Fixed operator associativity (addition/subtraction were previously right-associative)
