10.5.3 update? Follow

Hi list,

today i downloaded and installed version 10.5.3 of intellij idea
UltimateEdition. I wondered why i was not asked to update my current
10.5.2 to this version. Now it seems that the version number was not
updated or that i got a wrong version from download.

So my question is, is it advisable to use this 10.5.3 version or does
another update for this update is in line?

regards,
tilman
