I don't use the package but recently there's been some commits related to HTTP 1.1 which is possibly related.

Thanks @jamesmacwhite. The most recent commit is for version 2021-06-03-1: https://github.com/openwrt/packages/pull/15779

I started to get a lot of errors and DNS resolving stops working after a while.

daemon.info https-dns-proxy[1406]: [E] 1627803675.493089 https_client.c:205 No response

Probably this issue https://github.com/openwrt/packages/issues/16058

Why there is no package update for this?

Same log message very frequently (every few seconds/minutes as long as there is DNS request) as OP in 21.02.0 release, but no error message or any noticeable impact (so far). I can provide more information if needed for debugging.
