PSPDFKit 2.13.0 - Add support for 'Widget', 'File' and 'Sound' annotation types. New supported actions are 'Rendition' and 'RichMediaExecute'. Ink/Circle/Ellipse etc annotations now save their last used color independently. Improve selection knob handling, adds several translation strings, tweaks the text parser glyph separation code to cope with non-default separator characters, cleans up delegate handling in PSPDFSearchViewController, handles edge cases with several UIWindows and fixes a bunch of other issues.
