Full Release Notes

## What's Changed
This is a security release. Please upgrade as soon as possible using `Tools > Upgrade/Downgrade`.

Anki's local media server did not sufficiently validate requests, which could allow a malicious website to read local files while Anki was running. This had the potential to affect mostly Firefox and Safari users. Chrome already restricts local network access. Thanks to the great Tavis Ormandy (@taviso) for the report.

All other fixes and new features since 25.09.2 will follow in a separate beta release.

## Installing

- If you're a new user, please grab the latest launcher from https://apps.ankiweb.net
- If you already have the 25.09 launcher, you can use Tools>Upgrade/Downgrade inside Anki.
- If you have an older launcher/Anki, please grab the latest launcher first, as the older one may or may not work.
