0.23.0

Added

• Translation into Simplified Chinese. (Thanks to @2013ZRZ, it's the first community translation of Gauguin!)
• Switch to compact key pad buttons and alter the layout automatically if a grid with size greater
  than 9 gets played and the display dimensions are phone wise limited. (Thanks to @mccartney for the idea!)
• New option the allow grids with size greater than 9 to obtain most of the screen, which means
  getting a rectangular (that is a non-square) grid layout. This may look a bit less elegant than
  the usual one, but features more space to display readable pencil marks and so on. (Thanks to @mccartney for the idea!)

Fixed

• The info box shown when finishing a game gets no longer squeezed if there is not enough space left
  for it. Instead of, the box may overlap the grid.
  This is not pretty, but a kind of workaround especially when using a rectangular grid shape,
  minimizing the space left to be used by e.g. this info box.

0.22.1

Fixed

• Fixed popup showing difficulty ratings in colors missing necessary contrast to be readable. (reported by mccartney)
• Fixed hint popup not showing when using landscape orientation on a phone.

0.22.0

Added

• Added all difficulty levels of 7x7 and 8x8 grids.

Removed

• Removed migration of old save file format. The new format has been introduced in version 0.18.0
  in January 2024. Every version from 0.18.0 until including 0.21.1 migrates all saved games at app
  start automatically.
  If you update from <= 0.18.0 to >= 0.22.0, all games will be deleted.

Fixed

• Fixed restarting a solved game. (reported by MageDelfador)
• Fixed display of the chosen numeral system in new game screen.
• Fixed minor layout issues.

0.21.1

Fixed

• Fixed the hint popup blocking the following tap in the way that the game seems to not respond.

0.21.0

Added

• Added all difficulty levels of 6x6 grids.
• Adds a icon on the main screen to indicate if the current game values are not calculated via the
  usual decimal numeral system. The icon will show the larger digit of that numeral system, that is
  2, 4, 8 or F (indicating the hexadecimal system). (reported by sideria)

Changed

• Re-implements the hint popup: It got more colorful and should indicate at first sight if there are
  any errors by different background color and icon. The popup is disposable via a single tap at
  any place on the screen. (idea by tuxiqae)
• A long tap on a empty cell now copies common pencil marks of the cells in the same cage.
  Works on an empty cell (no value set and no pencil marks) if all non-empty pencil marks of the
  other cells of the cage contain the same or a similar set of pencil marks.

Fixed

• A solved game could not be restarted. (reported by MageDelfador)
• Avoids statistics diagrams to show only a part of the data. (reported by mccartney)

0.20.0

Added

• When solving a game, the keypad gets swapped by a card view which states the win of a game. It
  also shows if it was the first game solved ever, or the first kind been solved, or a best time
  which could be made.
• Added more detailed statistics. After solving at least one game, three diagrams visualize
  • The difficulty of the games solved.
  • The play time of the games solved.
  • The streak history of all games.
    There is currently no statistics by game variant. Feedback warmly welcome.

Changed

• Move the popup messages of the main screen to the absolute bottom of the screen, now covering the
  bottom app bar. Avoids covering the bottom row of number buttons when checking if there are errors.
• Mark 'Fast Finishing Mode' as stable.
• Show hours of play time only if the game lasts longer than one hour.

Removed

• Removed message when cheating/revealing cells. It seemed to be not motivating at all.
• Removed the possibility to shift the keypad from center to the left and right.

0.19.1

Fixed

• Avoid static color at main top frame when using dynamic colors. (reported by mueller-ma)
• Fix pencils marks of new games when auto filling single cell cages. (reported by mueller-ma)
• Fix restarted games to show recently modified cells of the previous game. (reported by s0lst1ce)

0.19.0

Added

• Added all difficulty levels of 4x4 and 5x5 grids.
• Added support of dynamic colors. (reported by mueller-ma)
• Added new preference to set the maximum size of a grid cell, from 24 dp to 96 dp.

Changed

• Converted images from PNG to WebP to reduce download and app size.

0.18.0

Added

• Added all difficulty levels of 3x3 grids.
• Added new preference to automatically fill single cages when starting a grid. (requested by mccartney)

Changed

• Limit maximum size of a grid cell to 96dp. Avoids overly huge cells.
• Grids now get saved via Yaml files. A migration of the old XML files will be triggered
  automatically when starting the app.
  This enables further development of grid types, removes a lot of legacy code, a relevant technical
  dept and makes the main developer sleep better.

Removed

• Removed grid size 2. From now on, the minimum size of a grid is 3. This is due to three facts:
  • Not all variants of 2x2 grid could be calculated successfully.
  • The difficulty values of 2x2 grids were nearly all < 1.0 which would turn into misleading
    difficulty levels reaching from 0 to 0 or such things.
  • I think nobody actually plays such small grids.
    If you had faith in 2x2 grid, give me a ping and thus motivation to include such grids.

Fixed

• Fixed load screen loading the wrong grid when clicking directly on the card surrounding the grid.
• When saving a grid and loading it, the current options where not saved until now. From now on, you
  can save a grid, go to the new game screen and alter any option you like. If you load your saved
  grid, all options where taken from that saved game. Previously, you could be stuck with e.g. a 6x6
  grid with the values 1..6, but altering the values between saving and loading to values 0..5 lead
  to a loaded grid, demanding values 1..6, but showing the key pad values 0..5.
• Loading a saved game via directly clicking on the grid area loaded the wrong game.
• Fixed Fast Finishing Mode to display the value of the selected cell.
• Fixed grids showing binary, negative numbers to display proper values.
• Fixed old grid flashing when a new grid was started. (reported by avipars)

0.17.0

Added

• Added a popup displaying the difficulty levels and their respective boundaries. May be reached by
  • Tapping at the difficulty info at the top bar on the main screen.
  • Using the info icon near the difficulty choice in the new game screen.

Changed

• Changed appearance of cells dealing with cheating and errors:
  • Revealed cells appear in gray scale.
  • If a cage a filled but does not match its math result, all cells get an red background and the cage gets a red outline.
  • If two cells in a row or column get filled with the same value, both cells get a red background.
  • When using the menu item 'Show errors', all wrongly filled cells get a red background and the value is displayed in a red color, too.
    This should clarify if a cell was revealed (grayscale), if there is an error regarding the cell (red background) or if the value itself is wrong (red value).

Fixed

• Fixed 'Show errors' which did not work at all.
• The popup to inform that a game was won gets dismissed as soon as the user starts another game. (reported by isHiteshBehera)
• Fixed deactivated number button colors in light theme which used the same colors as active ones.
• Fixed inconsistent appearance of the hint button of the main screen.
