@kdambekalns or @robertlemke it would be great to get this in.

If you see a way to make this compatible with oder version i will adjust the pr.

We have another asset source that can be installed on Neos 7 and before, I'll check what I did (or did not) do there…

[mficzel]

@kdambekalns the description is corrected, the major problem for compatibility with older neos versions is the change of the doctrine migration base-class. The asset-source api itself only adds two methods that will not do harm in an older Neos.

the major problem for compatibility with older neos versions is the change of the doctrine migration base-class.

@mficzel I checked, and the Canto asset source works with Neos 4.3+ even though the DB migration looks "fresh": https://github.com/flownative/neos-canto/blob/main/Migrations/Mysql/Version20210701152625.php

Granted, Pixxio uses Doctrine\DBAL\Migrations\AbstractMigration – but that is available even in a Neos 4.3 setup for me. And could be changed to Doctrine\Migrations\AbstractMigration just fine.

I think it's more the PHP version that plays a role here? This is what I checked the Canto asset source against:

@kdambekalns if the migrations are fine it should work in older Neos versions. I relaxed the composer constraint accordingly.
