Q4 Core Release for 2.4.4 release line?

Hi all,

We’ve just updated our Magento site to Magento 2.4.4-p1 and PHP 8.1.

Looking ahead to Q4 there is no planned 2.4.4-p2 but there is a security update planned for the 2.4.5 release line?

Does this mean we need to update to Magento 2.4.5-p2 to stay up to date on security patches?

Why did Q3 cover 2.4.5, 2.4.3 and 2.3.7 and then q4 only covers 2.4.5?
