What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **security** — Fix insufficient validation of requests in local media server that could allow malicious websites to read local files while Anki was running

##### 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.
