Revision History

• Version 1.0.5 - Fixed bug that caused splash screen to appear every launch.

• Version 1.0.4 - Updated to work with firmware 1.1.3. Updated pop-up menu accessed by clicking the HP logo.

• Version 1.0.3 - Adds Preferences menu with the ability to customize keyclicks and automatic checking for updates. Tap on the HP logo to the right of the display to access the new features.

• Version 1.0.2 - Fixes bugs in the keypad and display. Multi-key presses should now work. For example, the "ON" & "." sequence for changing the digit separators now works. Also, the "f", "PREFIX" function now properly displays the mantissa while "PREFIX" is held down. Also fixes the display of digit separators which was broken in the last version and slightly enlarged the valid "hit" area for keys.

• Version 1.0.1 - Adds persistent memory. When you exit HP-16C and return to the springboard, the calculator will remember its program memory and registers when it is next launched.

• Version 1.0 - Initial public release.
