Hello everyone, I'm the developer of Bactron Studio. As the title suggests, the game has been updated to version 1.4. Here, we'll summarize the features iterated in the previous 1.3 version:

1. Steam Workshop has been deeply integrated into Sudoku Bactron, allowing players and the community to build a harmonious ecosystem together.

We've also prevented [unsolvable]/[incorrect] Sudoku puzzles from being uploaded to the Steam Workshop. So you can confidently take on community-created Sudoku levels.

2. Added Note feature and Pencil toggle to the main Sudoku game (toggle with Q key)

A Sudoku game can't go without scratch notes! We know some players wanted this feature. So here it is!

3. Added Auto Notes Hint — when enabled, the game will automatically suggest possible numbers as notes in empty cells. This is a hint tool, not a cheat, and is completely optional.

4. Completely redesigned the Level Editor UI — a cleaner toolbar layout with Validate, Solve, Test, and Generate buttons in a dedicated sidebar, plus grid size options ready for future expansion.

5. Revamped the Tutorial experience — fixed layout issues where UI elements would shift, merged chapter info into a single clean display, and overall improved the flow for new players.

6. Full support for 4x4 and 6x6 boards — experience Sudoku in a different way. You can select the board size you want to generate in the settings page.

7. Completely redesigned the Workshop interface. Now supports tags for 4x4 and 6x6 boards.

8. Optimized Sudoku generation. Also fixed the issue where 4x4 and 6x6 boards would generate incorrect or unsolvable puzzles in minimal cases.

9. Refactored the settings page and options state.
