18.11.xx.yyyy ()

New features

  • library (wel): Added features to draw multiple lines and polygons, to fill polygons, and to enable anti-aliasing when using GDI+. Added features to set dash styles and line joins for a pen when using DGI+.


  • library (uuid): Marked {UUID_GENERATOR}.generate_uuid as a class feature and made the code of the class SCOOP-compatible.
  • library (base): Updated CHARACTER_PROPERTIES to use Unicode 11.0.0 instead of 10.0.0.
  • compiler: Implemented direct code generation for {CHARACTER_8}.minus and {CHARACTER_32}.minus.

Bug fixes

  • code analyzer: test#codeanalysis031 - Fixed a bug when a previously assigned variable was reported as unread (CA020) when it was both a target of a creation instruction and an argument to the corresponding creation procedure.
  • compiler: bug#19449 (test#final120, test#final126, test#runtime001) - Fixed a C code generation bug that could lead to wrong results of an equality test for references in particular cases in finalized mode when the right-hand side expression triggers GC.
  • runtime: bug#19242 (test#runtime022, test#runtime023) - Fixed a bug that could lead to object heap corruption when an argument or a local of an expanded type with (recursively nested) reference attributes is passed to a feature that triggers GC.
  • EiffelStudio: Fixed a bug that caused creation of generated files at a higher level than requested and using wrong names (such as Documentationtest.xml instead of Documentation/test.xml) when exporting to XMI.
  • EiffelStudio: Fixed a bug that might cause an exception when performing multiple switching from an item with an existing diagram to another one in a diagram tool or when switching between BON and UML views multiple times.
