0.50.0

Changed

• Split between a 'nishio solution' (using nishio or other probing techniques) and a general solution where one can fill all remaining cells via some simple logic. The further solution may be converted into an opt-in preference in the future.

Fixed

• Fixes a crash at start up if the current save game file was corrupt. (reported by @HeikoxE)
• Use multi line titles of preferences, avoids long titles to be cut of. (reported by @Mixaz017)
• Initial pencil marks and filling single cases did not work if a game was restarted. (reported by @Mixaz017)

0.49.1

Fixed

• Fixes the feature "Nishio solution" to treat a solution as valid if it contains errors. (reported by @dansan984fit and @keiligch)
• The preference dealing with broader cage frames does not change the inner cage drawing. (reported by @Cqoicebordel)

0.49.0

Added

• Added a new preference to draw broader grid cages, to enhance readability and accessibility. (Reported by @Cqoicebordel)

Changed

• The display of cells whose possible values got changed by filling another cell changed from using a frame around these cells to using a slightly highlighted cell background. This should help to detect the grid cages without distraction. (Reported by @Cqoicebordel)

0.48.3

Fixed

• Fixed inconsistent Java version of toolchain to always use Java 21 to make F-Droid builds work again.

0.48.2

Added

• Adds challenges as new feature (available in debug variant only). Enables the user to play
  pre-calculated grids which are either very easy "zen" grids or the most hard grids which could be
  calculated, but still being solved via the upcoming Human Solver difficulty rating.

Changed

• Changes internal game lifecycle logic.
• Bump Java version of toolchain from 17 to 21 to make F-Droid builds work again.

0.48.1

Fixed

• Version 0.48.0 APK was not in sync with git, so here comes version 0.48.1

0.48.0

Added

• The detection of a possible solution to show a button to check this solution was enhanced: It
  supports cells without a possible filled in if this cell is in a row or column which was already
  filled out completely except this single cell. Then, the remaining value of the row or column will
  be checked. (Reported by @spanezz)
• The upcoming Human difficulty algorithm now detects more variants of nishio (that is solving by
  propagating possible values) when calculating the difficulty of a grid. Currently only available
  in debug builds.

Changed

• At app start, all saved grids are tested if they need a migration to a newer save game format
  until now. This gets executed in the background to speed up app startup.

0.47.0

Added

• Add a preview when choosing numbers in new game dialog.
• Detect if all remaining unfilled cells contain exactly one possible number and show a button
  to solve the grid if the given values are correct.
• The upcoming Human difficulty algorithm now detects a simple variant of nishio (that is solving by
  propagating possible values) when calculating the difficulty of a grid. Currently only available
  in debug builds.

Fixed

• Removes unwanted calculation of the upcoming Human Solver when calculating a new grid.

0.46.1

Added

• All diagrams of the statistic screen now feature maximizing them to a full screen view.

Changed

• Various optimizations of layout of main screen.
• Upcoming difficulty algorithm got performance speed ups.

Fixed

• The main screen on large displays may not show all cells of the current grid.
• Loading state aka Ferris wheel animation was distorted at small sizes and has been fixed.
• Loading state aka Ferris wheel animation has been optimized for large size displays.
• The preview in new grid screen gets calculated faster.
• Version number in menu was missing.

0.45.0

Added

• Adds a confirmation dialog if a user requests help by e.g. revealing cells. This should avoid an unwanted reset of the current streak. The dialog only gets shown if the action would actually break a streak. (reported by @Mixaz017)

Fixed

• Fixes statistics screen for >999 games played: Avoids unwanted line breaks by using auto size texts. This optimizes screen layout for small devices like old phones. (reported by @Mixaz017)
