Changelog for "Universal Enigma"
================================

Version 2.0 (January 2016)
-----------
- Changed preset configurations: Enigma N (has plugboard); G-111 (no plugboard)

Version 2.0 (October 2011)
-----------
* 12 Enigma models (I, M3, M4, D, K, N, R, T, A-865, G-111, G-260, G-312)
* Free combination of all features and components (model "Custom")
* Enigma-Uhr (stecker rotation)
* altogether 42 rotors, 10 UKW, 2 Greek wheels, 3 ETW, 2 wheel stepping modes
- Monitor 2.0: 
  - complete redesign
  - physically correct signal path, incl. Enigma-Uhr
  - dto. for rotated inner wheel wirings (ringsetting) 
  - dramatic speed-up in textfield-input mode (processes only last character)
  - display of coding rate (characters per second)
  - detailed model configuration info
- Plugs and Uhr can be de-/reactivated
- improved usability* by excluding some tab indices ("-1" for increment/decrement keys
  and QWERTZU keys) and changing tr/td-alignment for wheel selection menus
  (*navigate input fields using the Tab key)
- reformulated wheel/notch variables (closer to literature standard); adapted stepping
- significantly improved browser compatibility; keyboard now IE-compatible
- QWERTZU keyboard, plugboard, selection menus and +/- buttons are dynamically generated
- fixed memory/sync issue in Firefox with large input in QWERTZU text field
