The supported Python versions are based on the [trytond Changlog](https://foss.heptapod.net/tryton/tryton/-/blob/branch/default/trytond/CHANGELOG). The release dates are from the [respective announcements](https://discuss.tryton.org/search?q=%22Tryton%20release%22%20%23news%20order%3Alatest) and the end-of-life data according to [Clarification of the release schedule](https://discuss.tryton.org/t/clarification-of-the-release-schedule/6716).

Good job. Thank you.
Does anybody know if postgresql versions are also critical for some trytond versions ?

There was an [issue with sequences on PostgreSQL 10](https://foss.heptapod.net/tryton/tryton/-/issues/6789) which had been fixed 5 years ago and it was already fixed.
From my experience all supported series should support all supported PostgresSQL versions. (Take that statement with no warranty).

So all unsupported series should support PostgresSQL versions supported at its end of life date ?
That’s a good starting point to reinstall old versions.
Today I use the lattest Ubuntu LTS distribution at tryton release date as the per default OS context.
For example, I plan to distribute Tryton 7.0 on Ubuntu 22.04

Each series support PostgreSQL versions that was supported by PostgreSQL at the time the first release in the series has been published.

Hi,
I am curious about those numbers. Increasing up to 3.8 minimal python version on Tryton 6.8:
- technical decision as some code needs language syntax only available on python3.8
- just a random political decision. To support only 3 versions of python language.
Is not a big deal, but [Debian 10 LTS](https://wiki.debian.org/LTS) still on python 3.7, so this change force to use Tryton 6.6
