Ready for iOS 26!

Version 2.0.0 includes styling adaptions for iOS/iPadOS 26 and some accessibility improvements, along with other small corrections and enhancements. The changes in detail:

• Styling adaptions for iOS/iPadOS 26 have been applied throughout the app. In particular, buttons and backgrounds have a more rounded appearance and glass effect is used in some places. Buttons that are used in the headers of pages are now represented by symbols, instead of descriptive labels. Some content animations also work differently, such as when the explanation for help is revealed.
• More improvements to accessibility, including better support for very large text sizes.
• More refinements to the way the difficulty of a puzzle is estimated for new puzzles that are generated by the built-in puzzle generator.
• When the option to select the size of the next puzzle is enabled for the puzzle generator, a new settings option makes it possible to select the puzzle difficulty too. This replaces the option that previously existed, which allowed the skill level to be selected. If the target difficulty is outside the range that is normally supported by the current play mode, the puzzle generator switches to a suitable alternative mode automatically.
• On the settings page for layout & appearance, new screen layout options are available for iPhone. When the device orientation changes, players can choose to have the screen orientation switch back to the preferred orientation automatically. This may be a more convenient option than setting the orientation lock on the device. Players who like to play while lying down might find this feature particularly practical.
• The settings page now includes an option to cancel all changes, in addition to the option to apply the changes.
• When the setting “show if numbers add up correctly to the clue values” is enabled, an error is indicated if the number of squares between the blocks does not fit any valid combination for the clue value (in other words, if the wrong number of squares are sandwiched between the blocks).
• In the performance analysis, the use of help that is described in the summary section at the top of the page is now based on the percentage of puzzles for which help was used. Previously, it described the extent to which the help was used when averaged over all puzzles. This could mean it described the use of help as being frequent, even when it was only used for one puzzle.
• A fix to the progress reporting that is shown in the Challenge Trail. This was not informing of a promotion when a level was completed.
• A fix for an issue with the Puzzle Generator Preview, where a change to the play mode was not actually taking effect.

The styling changes are seen when running with iOS/iPadOS 26. When running with older versions of iOS or iPadOS, the styling is still the same as before.
