# Release Notes

## May 12 2026, Monday

1. Added **Grid Start** dev panel card with a dropdown for preset board distributions and five percentage input fields (Base, Level 1, Level 2, Level 3, Level 4)
2. Presets: **Standard** (existing random initialization), **Level 1 and 2 Full**, **Level 2 and 3 Full**, **Chunky** (0 / 10 / 60 / 25 / 5), **Fluffy** (0 / 5 / 40 / 15 / 40)
3. Selecting Standard blanks and disables the percentage fields; selecting any other preset populates them
4. **Init Grid** button applies the distribution and restarts the board; if percentages don't sum to 100 they are normalized automatically before applying
5. Initial board auto-merge on startup is now gated on the **Hyper Merge** setting — the board no longer auto-merges at load unless Hyper Merge is enabled

## May 3 2026, Sunday

1. Added **Hyper Merge** checkbox to the Grid Hint dev panel card
2. When enabled, a cell auto-merges as soon as its four smaller dots are filled — no need to drop on top
3. Merges cascade upward: if the auto-merge completes a parent cell, that merges too
4. Base_Level → A_Level (16px → 32px) merges are excluded from auto-merge
5. The initial board now auto-merges any cells that start in a complete state (B_Level and above)

## April 28 2026, Tuesday

1. Changed default **Grid Hint** to **Level Up**
2. Changed default **Drop Tolerance** to **1 unit from dropzone**

## April 27 2026, Monday

1. Added **Level Up** grid hint mode to the dev panel
2. No grid lines are shown by default during piece drag
3. Grid lines appear only when the drop target would cause a merge at B_Level (64px) or higher
