composer require slim

[ChrisChristou]

There is a 2.6.2 release of slim/slim but espocrm requires 2.4.2 is there a reason for that or can i update ?
There is even a version 3 what about that?

Any reason to upgrade? New version is not backward compatible.

security concerns mostly thanks.

Maybe we need to apply those security fixes manually if they exist.
