• 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.

• The setting "Registers" is now part of a saved program. • Improved compatibility with a real HP-34 when recalling statistics registers • Visual adjustments for iPhone 16 Pro and iPhone 16 Pro Max

• Added warning when attempting to replace a Sample Program. • Added "GTO + +" (supplementing "GTO . ." and "g END") to address the last step of a program in both RUN and PRGM modes. • Optimized SOLVE function. • Added Example 2 to sample program "[A38]-Disc. Cash Flow Analysis".

• After computing an integral, the "uncertainty" stack register Y contains the current "Integration Accuracy" setting (0 = Best, 1 = High, 2 = Norm). • The "Integration Accuracy" setting is now stored along with the program. • Added "-" following the step number in PRGM mode, as on a real HP-34. • The display now may show dashes on lengthy calculations. • Verified and cleaned up descriptions of many sample programs. • New sample programs added: "Double Integrals" and "Memory Game and Trainer". • Bug Fixes: - The previous version 2.5 didn't drop the stack on y^x. - Suppressed illegal key sequences, like "LBL CHS" or "LBL +" etc. – "SOLVE lbl" is now correctly listed as "14 73 lbl", not "14 .lbl" (where lbl = 0..9, 11, 12). - In PRGM mode, two consecutive RTN steps could show up at the end of a program.

• Unicode blanks are converted to regular blanks when pasting program text. • Added sample program "Grazing Goat" • Runs on Apple Silicon Macs (see notes on homepage cuveesoft.ch) • RPN-34 CE requires iOS 12.0 or later. • Bug Fixes: – Applying the integrate function to very large numbers could cause a crash. – The "What's New" would reappear even when told not to.

Fixed an issue where program lines cut using "g PCut" would not always get pasted correctly.

• Haptics Set the haptic feedback level in the calculator's settings. „Sounds & Haptics“ / „System Haptics“ must be on in the iPhone's settings. • Improved Indirect Branching Labels .0 and .1 may now be targets of indirect branching via the I-register if extended registers 0..99 are enabled. • 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.

• Minor improvements Bug Fix: • ISG/DSE commands were susceptible to internal rounding effects

• Print (or mail as PDF) the program or its description • Improved accuracy in extreme cases of y^x with positive, integer x. For example, 1.0000001^(2^27) = 674530.4707, not 674530.4760 • Stack shows localized formatted value while number is being entered • 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.

• Improved LN(x!) function: - Higher accuracy - Now returns y and z such that x! = y * 10^z (where z is an integer) • If SOLVER is called from a program, and a root is not found, the program doesn't stop anymore. Instead, the next step is skipped. This allows iterative searching for roots under program control. • Improved stack display (swipe display right to show): - Doesn't cover top bar functions anymore. - Shows unformatted values of x and Last x. - Long-press to directly call up the register view. - Correct digit entries by swiping left. • Email programs directly from the program list • Replacing registers by pasting a program into the display is now optional • Support for iOS 13: Dark Mode, file sharing Check out the new Download walk-through on the website (under "Sharing".) Bug fix: • Executing the summation command ∑ with a very large argument would cause a crash RPN-34 CE now requires iOS 11 or later.

Fixed an oversight that caused the low-battery warning to come up much too early. Sorry for any inconvenience!

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

• Register I is now formatted in Register View for easy interpreting in ISG/DSE commands • New program added: "Locating the Moon"

• Optional stack display (swipe display right/left) • Cut and paste any number of program steps, even between programs! • Set flags are shown as highlighted register number in Register View • Flags are now saved and loaded along with programs • Select integration precision in Settings (Norm/High/Best) • Added two program pacs ("Student Engineering Applications" and "Surveying Applications") • Improved reliability of comparisons Bug fix: • In rare situations, executing Integrate or Solve from the keyboard would not stop correctly after the calculation
