I can't remember the last time a new HTML element came along. Yesterday, <search> shipped in Safari 17.0 (the first browser with support).

You can start using it to build websites TODAY, even when most of your users still don't have support. We explain why & how at the beginning of this article: https://webkit.org/blog/14445/webkit-features-in-safari-17-0/
```
<search>
<form action="/search">
<p><input type="search" name="q"> <input type="submit" value="Search!"></p>
</form>
</search>

In the world of images & video, Safari 17.0 includes:
- the `image-set()` arguments `resolution` and `type`.
- JPEG XL
- HEIC
- AV1 on devices with hardware support
- Managed Media Source API (better MSE)
- an overlay for `<video>` that shows media player stats (for developers)

If you have a pet, please get pet insurance if you don't have lots of disposable cash in case of an emergency. I pay $63 a month for Truth (5 y/o), and $155 a month for strange (12 y/o). Truth had a medical emergency last night, and Trupanion covered 17k without fuss. Absolutely worth it. Happy to answer any questions. https://refer.trupanion.com/cameow-2
