• Improved compatibility with iPhone Air and iOS 26.

Non-volatile stack: when reloading the app, the stack is now restored along with all registers.

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

• Added warning when attempting to replace a Sample Program. • Increased pause length to 2 seconds • Visual adjustments to iPhone 16 Pro and iPhone 16 Pro Max

• Clarified program example on info screen by adding an instruction. • Internal optimizations and cleanups. • Modified info screen to avoid clipping by the Dynamic Island.

• Runs on Apple Silicon Macs (see notes on homepage cuveesoft.ch) • RPN-32 CE requires iOS 12.0 or later

• Haptics Set the haptic feedback level in the calculator's settings. „Sounds & Haptics“ / „System Haptics“ must be on in the iPhone's settings. • Program list view can be dragged down to dismiss it.

• Change the program listing font with a simple tap on the new button "F" • Apply a filter to quickly find any program. • Sample Programs may be hidden in the list of programs.

• New sample program "TVM - Time Value of Money" Run financial calculations involving payments, interest rate, present and future values, and periods or number of payments.

• When executed interactively, ISG and DSE do not change the program counter Bug fixes: • Deleting a block of program steps could result in wrongly adjusted branch targets in some cases • ISG/DSE commands were susceptible to internal rounding effects • RCi did not lift the stack when executed by a program

• Print (or mail as PDF) the program or its description • A program running longer than one minute will emit a short beep when executing the final GTO 00 command • Tap f or g, then P/R to see a 12- or 24-hour clock. • Improved accuracy in extreme cases of y^x with positive, integer x. For example, 1.0000001^(2^27) = 674530.4707, not 674530.4760 • Call up "What's New" anytime from Info screen • Compatibility with iPhone 12 Bug fixes: • Fixed display issues when using the iPhone in "Zoomed" mode • The RND function didn't work correctly in regions using a comma as decimal point • Double- or triple-tapping the empty program listing could cause a crash. • Setting the haptic feedback level didn't check sufficiently for the correct code

• Some programs have been added or updated. Be sure to execute "Reload Sample Programs" to refresh the list. Bug fix: • Instructions involving register arithmetic with extended registers were not correctly encoded

• NOP instructions targeted by GTO or GSB are automatically changed into LBL instructions • Operations and decimal point following STO or RCL may now be added or removed in any order • New instructions: exchange X directly or indirectly with any register, swap primary and secondary registers, and more (see website) • Improved import of HP-25 programs created by the GO-25 simulator. ("Share PRGM" to "Pasteboard" on GO-25, then long-press display of RPN-32 CE in program mode and paste.) • Haptic feedback may be turned off and on: – Store 1939010X in R0 to set amount of feedback (where X = 0: no feedback, X = 3: maximum feedback) (Hewlett-Packard Company was founded on Jan 1, 1939) Bug fixes: • Deleting a range of steps (DLx,y) did not correctly adjust targets of GTO and GSB in all cases • Wrong translation of instruction RND imported from GO-25 • Angular mode didn't get exported when sharing in calculator view

• Register view shows localized formatted value while number is being entered Bug fix: • Using scientific notation could crash the app in some regions, i.e. Australia, Sweden, Slovenia.

• Support for iOS 13: Dark Mode, file sharing • Email programs directly from the program list • Replacing registers by pasting a program into the display is now optional • Many under-the-hood optimizations Check out the new Download walk-through on the website (under "Sharing".) Bug fixes: • The keys GTO, STO, and RCL didn't cancel a pending flag command • Executing the summation command ∑ with a very large argument would cause a crash RPN-32 CE now requires iOS 11 or later.

New features: • New editing commands in programming mode: – DELx,y: delete range of program steps – DELEnd: delete steps from current position to end of program Bug fix: • The instruction GSB 90 could not be entered

New features: • Long-press program listing to change font of description from proportional to non-proportional and vice versa. • New program "Curve Fitting" added

Fixed crash on double-tapping GTO nn in program listing when step nn didn't exist

• Register R.9 is now formatted in Register View for easy interpreting in ISG/DSE commands Bug fix: • Commands STi and RCi were not correctly assigned to key codes

• Optional stack display (swipe display right/left) • Indirect addressing of all 20 registers via the R.9 register (on f and g keys) • Set flags are shown as highlighted register number in Register View • Flags are now saved and loaded along with programs • Warning on deleting program memory or program files • On-screen error descriptions • Improved reliability of comparisons • New programs: Gamma Function (Spouge), Incomplete Gamma

• New sample programs: – "Solve for f(x)=0 Newton" – "Simult. Equations in 3 Unknowns" – "LogFactorial" • Improved programs: – "Simult. Equations in 2 Unknowns" – "Fibonacci Numbers" • Improved Program Listing (tap "?" in listing screen) • New buttons at top to select TOP, MID or END of program • Built-in descriptions of top functions (see Settings) • Except on step 00, pressing R/S shows next command to be executed; releasing R/S starts executing • Renamed button "Load" to "Save" • Changed "Undo digit" sound to same as with other CuVee calculators • Support for late 2018 iPhones Bug fixes: • Improved reliability of DSE and ISG commands • Digit separators were not cleared when starting number entry with EEX

• Improved compatibility with iPhone X Bug fixes: • Incorrect app icon shown when installed on iPad • Number format issues and possible crash when using the EEX key

New sample program added: • Progressions (arithmetic, geometric, harmonic) • Improved trig functions for extremely small angles • Support for iOS 11 Bug fixes: • Separators didn't always disappear when changing display mode to SCI or ENG • Copied display values with exponent could be improperly formatted

New sample programs added: • First Order Differential Equations • GCD and LCM (Greatest Common Divisor and Least Common Multiple) • Rectangular / Hyperbolic Polar Coordinates Conversion • Rectangular / Spherical Coordinates Conversion • Sum of Digits Game

• New program "Numerical Integration" (tap "Reload Sample Programs" to see it) Bug fixes: • RND didn't work correctly on certain values • Deleting steps caused wrong address corrections in some cases
