I have a web site in 2.3.6-p2 which does not give problems.
Is it worth upgrading to 2.3.7? I don't see that there are many new features and code improvements, rather, quite the opposite, imposing php 7.4 and more updated versions of redis, mysql, elasticsearch etc.
Opinions please.
I think if you want to use php 7.4 then 2.3.7 was released for that, I have tried using php 7.4 with 2.3.6 got bunch of errors
I think upgrading the version to 2.3.7 is nothing to worry about. The php7.4 version will have some minor bugs related to custom code but I think it is very rare.
