Patchset installs RMS 13.2

Hi Community

I have downloaded and installed RMS 13.2 from the edelivery.oracle.com site and I am now attempting to bring this up to the latest patchset - 13.2.6

As per the release notes and installation guide, I am downloading (and will then install) the 13.2.1, 13.2.2, 13.2.3, 13.2.4, 13.2.5 and then 13.2.6 patchsets.

I also notice a series of other intermediate patches - e.g. when I search for 13.2.3, I also find patchsets for 13.2.3.1, 13.2.3.2, 13.2.3.2.1, 13.2.3.3

Do I need to download and install these intermediate patchsets, or do the intermediate patchsets get rolled up in to the next patchset (in the above example - 13.2.4).

In other words does the code delivered in 13.2.3.x get included in 13.2.4 ?
