Python 2.3.3 requirement for Plone (CMS)

[ronfar]

Has anyone successfully installed Python 2.3.3 and/or Plone (CMS)? The latter seems to require Python 2.3.3 but currently, with PLesk 7.5.2, version 2.2.3 seems to be installed.

I just want to know if it is safe to install Python 2.3.3 and what the consequences could be for PLesk if I do...
