Monterey 12.7.5 OCLP version 1.5.0 - Updates

Hi, Guys How do I know when I get updates on Monterey 12.7.5 OCLP version 1.5.0, on my iMac (21.5-inch, Mid 2011) - Model : A1311.

Because it's not showing updates, other thing I don't want to upgrade to Sonoma, I am fine with Monterey,,have no problems at all.

Thanks

Kind Regards
