 How did you manage to get your 3.3 with a newer GEOS or did you compile
 that GEOS yourself?

 something like that ?

 I don't think we can do that with GEOS, because people are allowed to run
 any GEOS that is supported for that version of PostGIS.

 Also GEOS tends to be a system library shipped with the OS, so it's hard
 for a user to upgrade it short of not using the distro and compiling their
 own GEOS.

 Also it's hard to know what the latest (even micro version) is of GEOS
 since PostGIS and GEOS have slightly different release cycles. GEOS we try
 to release a new minor version about a month before the PostGIS that
 exposes features of that version comes out, but the micro releases of each
 are detached and happen whenever a sufficient number of bugs or serious
 bugs piles up for the respective software.

 The best we can maybe put in that note, is "You are using a GEOS version
 that does not support all the functions of this release.  As such several
 functions will be disabled"

 But none of that is going to help with this ticket since your issue is you
 are running an out of date geos for your micros
