 Multicorn Python3 Foreign Data Wrapper (FDW) for Postgresql.  Tested on Linux w/ Python 3.9-3.13 & Postgres 14-18.
 
-Testing is underway for supporting Python 3.13 and is expected in v3.1.  v3.1 is also expected to support pg18.  
-Newest versions of major linux distro's (Ubuntu 24.04 & EL10) are all still using Python 3.12 so sticking with using 3.12 is advised in the short run.  
-It's also advised that if you are still using EL9, and it's default Python 3.9, upgrade to using Python 3.12 in a venv because Python 3.9 is already deprecated and will soon be unsupported by this extension.
+Our latest release, v3.1, supports thru pg18 (and has some testing against Python 3.13).
+Newest versions of major linux distro's (Ubuntu 24.04 & EL10) ship with Python 3.12 so sticking with using 3.12 (instead of 3.13) is advised in the short run.  
+Python 3.9 is already deprecated by the CPython community and will soon be unsupported by this extension; use 3.10 thru 3.12 instead.
 
 The Multicorn Foreign Data Wrapper allows you to fetch foreign data in Python in your PostgreSQL server.
