Upgrade/Patch MySQL 5.5.42-37.1 Percona Server to 37.3

Hi,
I am new to MySQL world. We have MySQL 5.5.42-37.1 Percona Server. Does Percona releases Critical Patch Update ( Security related) very similar to Oracle database ( Critical Patch Update) ?
If not what is process to go from MySQL 5.5.42-37.1 to 37.3 ? Does process include installing new binaries, running some database patch script etc ? Can some one point to correct documentation ?

You can install Percona’s APT or YUM repo on the server and do an update/upgrade:

sudo apt-get update or sudo yum makecache

then:

sudo apt-get install percona-server-server-5.6 percona-server-client-5.6 or sudo yum install Percona-Server-server-56 Percona-Server-client-56

That should upgrade your mysql instance to the latest package from Percona repository.

You can also download a binary package from our website and install it accordingly to you server (varies for RHEL/CentOS and Debian/Ubuntu)

I see following guide to upgrade from 5.5. to 5.6 but in my case I just want me to go minor version upgrade. Do I need to follow same process ?
