## Version history (last 5 releases)

### 2.3.2 — 2026-08-15

Version 2.3.2

• Fixed lowercase word lookup: searching "be" or "nice" now opens the regular
  entry (the verb/adjective) instead of the capitalized one such as "NICE"
  (an abbreviation). Thanks for reporting this!
• New default look: a brighter yellow theme.
• Home header text and camera/mic icons recolored for readability on yellow.
• "Related words" now shows as wrapping chips instead of one long line.
• Removed the pointless "1." on sections that only have a single entry
  (Origin, Usage…).

### 2.2.9 — 2026-07-28

A whole new Dunno.

We rebuilt the look and feel of the app from the ground up
— everything is cleaner, faster, and easier on the eyes.

- Fresh, consistent design that looks great in both light and dark mode
- Search, notebooks, and mock tests are simpler and more intuitive
- Smoother scrolling and quicker lookups
- Improved stability, plus dozens of small fixes

Open the app and see the difference.

### 2.2.8 — 2025-09-15

Fixed audio playback issue
