Version 3.9
• If "Enhancements" are set to "Off", loading an empty card will blink "0.00" and program memory will be cleared to NOPs, like on a real HP-65.

Version 3.7.6
• Backstepping from step 001 to 000 in modes UI and Plus is now supported. In addition, step 000 is labeled as "[TOP]".
• In vintage mode, typing "GTO.digit" and "LBL.digit" would not start a number entry.
• Also in vintage mode, single-stepping an instruction like LBL 5 would not be executed as on a real HP-65 when the mode switch was flipped to W/PRGM and back to RUN between steps "LBL" and "5".
[Thanks, Vincent]

• Long-press the circled info button to call up the "What's New" screen.
Bug fixes:
• [Vintage mode] Entering a merged code instruction (e.g. g NOP) at step 100 now works correctly.
• [Vintage mode] Single-stepping (SST) from step 100 in W/PRGM mode now shows 00 00, not step 01.
