CodeIgniter v4.5.0 Released!

I'm using CI 4.4.4 and was about to update to 4.5.1

i'm use to duckduckGo -> codeigniter 4 and in results use https://codeigniter.com/user_guide/insta...ading.html
but did not found 4.5.1 in the list.
The codeigniter.com site is not in sync with https://codeigniter4.github.io/userguide...ading.html ?

if this is a known probleme please forgive me
