What is new in Lunar 6.11.0

6.11.0

## Fixes

- The Lunar window no longer opens by itself when a Shortcut runs a Lunar action or activates Lunar
- macOS 27 crash fix

## Breaking changes

- Lunar now requires macOS 12 or newer

**Note:** this will most likely be the last v6 release. **Lunar v7** is a rewrite of the whole brightness control engine and UI that will be released in September-October, dropping support for Intel and macOS versions older than 14.0 to get rid of legacy workarounds and hacks that accumulated over the past 7 years.
