[Pharo-users] Spec2 Pharo8/9; icons

[Tomaž Turk]

Dear all,

What would be the best Pharo version to start building a Spec2 GUI for 
an app - Pharo 9 which is under development but with novelties in Spec2, 
or Pharo 8?

What's the best (easiest ...) way to import new icons into Smalltalk ui 
icons? Is there any special bitmap format to be considered?

Thanks and best wishes,
Tomaz
