2024-01-17: release 1.1.3

* Added C.LN1+X and C.E^X-1 functions. These are complex-capable versions of
LN1+X and E^X-1.
* Binary version: When converting binary to decimal, only use 17 digits when
actually needed. This prevents 0.1 from turning into 1.0000000000000001e-1,
for example.
* iOS version: Support for external keyboards.

2023-12-21: release 1.1.2c (Android only)

* Export State used f42 file extension instead of p42. Fixed.

2023-12-18: release 1.1.2b (Android only)

* Fixed file access for Android >= 11.

2023-12-12: release 1.1.2a (iOS and MacOS)

* Fixed startup crash, caused by a bug in Apple's latest compiler.

2023-12-06: release 1.1.2

* Fixed a bug that could cause a crash on startup.

2023-12-01: release 1.1.1

* CSLD? did not handle intervening XEQ/RTN. Fixed.
* FUNC did not detect previous FUNC/LNSTK/L4STK. Fixed.

2023-11-29: release 1.1

* Full-screen matrix and list editing (EDIT & EDITN)
* Added option to show LASTX at the top of the stack display area: DISP→LTOP
* Added option to show ALPHA at the top of the stack display area: DISP→ATOP
* Added option to show the state of flags 0-10 in the header: DISP→HFLAGS
* Added option to show an indicator for POLAR mode in the header: DISP→HPOLAR
* EDIT, EDITN, and INDEX now support editing lists, nested lists, empty lists,
and matrices within lists. See the Free42 web site for details.
* FUNC now hides the caller's RPN stack, so user-defined functions can use
functions like CLST and R↓ without causing side effects.
* User-defined functions can now be made to support 'stack lift disable'
properly. For functions using FUNC, this happens automatically, and other
functions can use the new CSLD? function (Caller's Stack Lift Disabled?).
* FNRM and UVEC, when called with very large parameters, could get incorrect
results due to overflows in intermediaries. Fixed.
* Fixed parameter bounds check in PIXEL.
* Windows, MacOS, and Linux versions: Keyboard maps now support separate
mappings for unshifted and shifted numeric keypad keys, and unshifted and
shifted Space.
