# Changelog

<!--
  Shown to players as a "What's new" popup. Add a new `## ` section at the TOP
  whenever you ship something worth announcing (new books, new features).

  - Each `## ` heading must be unique -- the browser remembers which headings
    it has already shown, so a heading is the ID of an entry. A date works
    ("## 2026-10-06"), or add a title ("## 2026-10-06 — New books") if you
    post twice in a day.
  - Editing the body of an entry that's already shipped does NOT re-show it;
    only a new heading does.
  - Supported markdown: bullets (- ), paragraphs, **bold**, *italic*, `code`,
    and [links](https://example.com). Anything above the first `## ` (this
    comment, the title) is ignored.

## 2026-10-23 — Two-board giants and button placement

- **Two-board Giants** books: 17x17 (four stars), 21x21 (five stars) and 25x25 (six stars), each with two boards sharing one solution. They sit alongside the existing 1-Board books in Giants.
- New setting, **Button placement**, replaces "Buttons also on bottom". Choose **Top** (the default), **Top & bottom**, or **Floating**, which keeps the undo/redo/reset/hint buttons pinned to the top of the screen as you scroll. If you use Cell colors, its palette follows the same choice. If you'd turned on "Buttons also on bottom", you're now on Top & bottom.

## 2026-10-21 — New books

- **3-Boards** books in Two Star (9x9, 10x10, 14x14) and Three Star (13x13, 14x14): three boards share one solution, and you need all three to find it. Any single board, or any two together, still leave more than one answer.
- **9x9 Symmetric** (two stars) and **10x10 Symmetric Twin** (two stars) in Symmetry.
- **Venn** now has a two-star book (10x10) in Rectangles.
- **13x13 Square Free** (three stars) in Playground.

## 2026-10-13 — Cell colors

- Added a new setting, **Cell colors**, that lets you color in cells while solving. It's off by default; turn it on in Settings.

## 2026-10-12 — Puzzles refreshed

- Most puzzle books were regenerated for consistency and quality, so many puzzles have changed.
