## Enhancements

Codegen debugging. Codegen debugging utility is more reliable at producing output for “large” and “very large” execution paths.

Transparency rendering option. A new rendering option for transparency bias definition has been added. Two options are available: “normal” and “msaa”.

Custom vertex shaders. Specific behaviors such as custom colors and interpolation can be applied to lines and markers using custom vertex shaders.

## Functional Changes

.NET changes. Visual Studio 2019 libraries are now shipped in .NET Standard 2.0, allowing customers to run their applications from .NET 4.5 to .NET 6. Sample applications as delivered are set up to run using .NET 5.

Marker color. Marker custom glyph color is inherited from segment when using `SetNormalColor` on the glyph and `SetExplicitColor` on other glyphs.

Hardware accelerated text. Highlighted text now uses the hardware acceleration path for all types of text, resulting in improved rendering performance.

Postscript export. Memory usage reduced when saving PostScript files.

Include paths. Memory usage reduced when using include paths in the segment tree.

Text spacing. Text aspect ratio and spacing is now slightly different due to a correction in the way FreeType fonts are handled.
