As well as some changes to the page meta, the refreshed article contains an FAQ section dedicated to HTTP/2 version support, with the key takeway being:
If you use HTTP/2, the Yandex robot indexes your site using the HTTP/1.1 protocol. However, there will be no conflicts with your server settings. The HTTP/2 version doesn’t affect the speed of crawling and doesn’t change the site’s position in Yandex search results.
HTTP/2 was not previously documented in the Yandex Webmaster help guides.
