Upgrading 3.0 to 3.0.3 ?

Hi guys

Is it fine if I will upgrade version 3.0 to 3.0.3 and skip the instruction in 3.0.1 and 3.0.2?

Thanks in advance.

The answer is always no.
If you skip a version, something is probably missing.

But in your case, it is not crucial.
But if 3.0.4 is released and you skip 3.0.3, then it might be crucial.

The upgrade instructions for each version from 3.0 to 3.0.3 have one or two minor things that need to be updated in your application directory. While you don't have to manually apply each version, you will have to check the upgrade instructions for each version and make sure you get everything updated properly.
