This is major development update including a lot of bug fixes (no? really?), changes, improvements and extensions. **wxRuby3/Shapes** (Wx::SF) is a pure Ruby 2D shapes and diagramming software library/framework based on wxRuby3 which allows easy development of software applications manipulating graphical objects (shapes) like various CASE tools, technological process modeling tools, etc. ## What's changed * refactor the serialization code into a separate gem [FIRM](https://github.com/mcorino/firm) with it's own improvements, optimizations and extensions (like XML serialization) * add many new arrow types (square, prong, cross-bar, etc. and combinations) * add BoxShape (incl. VBoxShape and HBoxShape) shapes with similar child management as wxRuby's BoxSizers * major changes and extensions of the 'demo' sample * lots of other changes, bug-fixes and optimizations Github: https://github.com/mcorino/wxRuby3-shapes Github-pages: https://mcorino.github.io/wxRuby3-shapes Rubygems: https://rubygems.org/gems/wxruby3-shapes
