As per Odoo documentation Odoo Support last 3 version ....
after release of Odoo 13 EE Odoo Support v11 EE,v12 EE & v13 EE .....
so what will do Odoo with Odoo 10 EE & Odoo 9 EE ?
its still need to pay for Odoo 10 EE and Odoo 9 EE ?
if user pay for that then why ?
or it's become open source ?
can we use odoo 10 & 9 EE Source Odoo for commercial use ?
Definitely the unsupported version not become open source.
so whats the logic behind remaining close source even not support by Odoo, strange ....
