## 2.9.1
* Bump vendored SQLite library to [3.26.0](https://www.sqlite.org/releaselog/3_26_0.html) to address [RCE bug: `magellan`](https://blade.tencent.com/magellan/index_en.html).

* Add flag to enable full-text search extensions (enabled by default)

It would definitely be tricky though because sqlite does not really have this
feature.
