I have read on Surachart Opun’s blog that 188.8.131.52 is available, but also that the patchset is now a full installation.
In the past, if you wanted to have 184.108.40.206 or 10.2.0.5, you needed to install both the base version, 220.127.116.11 or 10.2.0.1 and the patchset, 18.104.22.168 or 10.2.0.5. Very often the patchset itself was bigger and took more time than the base database installation.
According to Note 1189783.1, it is now possible to install 22.214.171.124 without having to install both 126.96.36.199 + a patchset.
if you are installing Oracle Database on a system without an existing Oracle Database installation, then you can simply install the release 188.8.131.52 patch set
