• Improved compatibility with real HP-45 when using D.MS conversions: – With "Extras" set to off (yellow key, then "+" key to toggle): same results as real HP-45 – With "Extras" set to on: improved results (no digits dropped by conversion) EXAMPLE Convert 12.345612: – "Extras" off: D.MS-> 12.58225556, then ->D.MS back to 12.34560000 – "Extras" on: D.MS-> 12.58225556, then ->D.MS back to 12.34561200

• Localized decimal point and separator appear only when “Extras” is activated. • Improved compatibility with iPhone Air and iOS 26.

When “Extras” are turned on ("Gold"-"+"), stack and registers are non-volatile.

When “Extras” are turned on, you can switch between grams/ounce and grams/troy ounce using gold-“x”.

• Faster startup – no delay until the first button press is recognized after switching on.

If "Extras" are turned on ("gold-key", then "+"): • A number like 9.9e99 will show up as 1.e100 when the format SCI 0 is selected. • Calling up the stopwatch (RCL ENTER) initially shows a running clock in 12-hour format. Store up to 10 time values by pressing any key from 0 to 9.

• Visual adjustments to iPhone 16 Pro and iPhone 16 Pro Max

• Corrects rounding errors of the 1/x function with large numbers in FIX format. • Vintage-45 now requires iOS 12 or higher.

• Storing 19390101 in R1 toggles key-flashing on and off. • Recalling 19390100 from R1 turns key-flashing off; recalling 19390101 turns it on. • Fixed a problem related to the STO and RCL instructions.

• Control haptic feedback (iPhones only): Store 1939010x in R0 to set the level to x (1..3, 0 for off). Recall R0 to see current level. „Sounds & Haptics“ / „System Haptics“ must be on in the iPhone's Settings. • Store 19390101 in R1 to toggle key-flashing on or off. (Note: Hewlett-Packard Company was founded on 1939-01-01)

Turn thousands separators on and off by pressing FIX followed by the decimal point.

• Results are now rounded to 12 digits internally digits, for better handling of chain calculations, e.g. 98.6, °F￫°C, n! doesn't produce an error anymore (thanks, Chris!)

• Corrects the behavior of the stack when using the additional unit conversions

• Fixes display issues when DISPLAY ZOOM is turned on

Compatibility with iPhone 12

• Key flashing may be turned off and on: - Store 19390101 in R1 to turn off - Recall 19390101 from R1 to turn on (Hewlett-Packard Company was founded an Jan 1, 1939)

Bug fix: • Using scientific notation could crash the app in some regions, i.e. Australia, Sweden.

• iOS 13 compatibility • Dismiss register view by dragging view down (iOS 13) Vintage-45 now requires iOS 11 or later.

• New conversion factors: m/ft and g/oz (tap gold-plus to show) • Changed "Undo digit" sound to same as other CuVee calculators • Single-tap on display now shows registers, double-tap shows app info • Improved trig functions for extremely small angles • Many under-the-hood refinements • Support of late 2018 iPhones

This update requires iOS 8 or later. • Calculator sounds mix with background audio and have their own volume control Bug fix: • Copy/pasting of time values in timer mode

• Non-standard functions may be toggled on and off (tap gold key, then plus key)

• Improved results for SIN, COS, TAN with very large arguments • Decimal addition/subtraction for higher precision

• If audio is playing on start-up, Vintage-45 will not produce any sounds

• HP-45 low-battery warning (all decimal points lit) if iPhone's battery drops below 5% • Supports 64-bit architecture Bug fixes: • Calculator didn't turn itself on (iOS 8) • LastX didn't work if RCL / n produced an error

iOS 8 users: If the calculator fails to turn itself on, tap the display once. • Full-screen display • Compatible with iOS 7 • Requires iOS 5.1 or later Bug fixes: • Register arithmetic now handles under- and overflow correctly • Fixed pasting values dropping decimal point in certain regions
