• Glk features

  • Changed glk feature support to a definition (I have not updated the WWI docs yet, because I wasn't sure how definitions are typically documented)
  • Added "feature" to the end of each
  • Added the various specific-kind-of-window features as features rather than phrases

• Windows

  • Renamed the "type" property to "window type"
  • Renamed the "reference number" to "glk window handle"
  • Added "window type" to end of each enum variant
  • Added window subkinds
  • Made the window functions safe or RTP raising
  • Fully track the opening/closing of the quote window
  • Exposed VM_StatusLineHeight
  • Added "say current line input of window" phrase (from Hyperlink framework #162)

• Events

  • Stop exposing Glk_Event_Struct_type - it now should be read just as the rulebook basis
  • Changed how the text input status is reset, to ensure it won't be inaccurate if someone adds their own "first glk event handling rule"
  • Made "set the glk event type" stop the rulebook, and then rerun the glk event handling rules again

• Misc

  • Made ShowRTP safe while input is pending, by calling SuspendTextInput/ResumeTextInput
  • Specified the before starting the virtual machine rules as first rules (and therefore had to reorder them too)

• To do:

  • Remove statuswin_cursize?
