Is cakephp 4.3.8 support over?

Hello,

Is cakephp 4.3.8 patch release support over?

I searched for an article about this, but couldn’t find it.

If possible, please let me know.

thanks

There is no such support.
Support is given on major and minor timelines (only).
So check 4.3 for example, which yes, with 4.4 out is now in security maintenance only.

As you should always upgrade to latest minor of a major right away, to be able to take further improvements and bugfixes without issues.
