Looks good. However, I don't have any php tools anymore on my pc (since I'm not developing in php anymore). I asked in issue #28 if someone could lcheck this. 👍

Otherwise I will get some php tools on my pc, however, could take a week or two.

Are the namespace changes really compatible back to Symfony 2.8? I would imagine they are not and a new major library release is necessary at which point now incompatible Symfony versions need to be dropped.

Unfortunately, my PR is wrong and it is no longer compatible with old version of Symfony - latest supported version may be 4.2 but I didn't verify it very carefully.

ATM we are using it with Symfony 5.0 and it works OK (we are using fork), so I don't have much time for testing - I will try to fix this on weekend, but I can't promise anything ;)

@advancingu We at least have an open issue to remove support for <= 3.2.

@mleczakm What does your fork look like? In the linked issue they said they just added |~5.0 to the composer stuff, is that all that is required?

[mleczakm]

@kobelobster there are more changes required (all of them are provided in current PR) to get it working

Okay, what I could imagine would be this.

The currently maintained Symfony versions are 3.4, 4.4 and 5.0 https://symfony.com/releases

3.4 will be in security mode starting near end of 2020 and only receive security fixes.

Although, a few questions, maybe you could answer them 😊👍 ?

• In your PR you removed symfony/monolog-bundle for 4.0. Intentional? Shouldn't this be re-added for 4 AND 5 as well?
• Like @advancingu said: Do the namespaces alsoo work in Symfony 4.4?

So, this would leave us with this

• Add support for Symfony 5
• Verify the bundle works for Symfony 4 and 5
• Remove support for Symfony 3 (in master, so upcoming releases only)
• Bump version to 3.0.0
• Refer in README.md that we still support 3.4, however no new features are developed and people should use the 2.3.0 version

Note: If the interfaces don't work on 4.4 I would say we create 3.0.0 with 4.4 support (without the adjusted namespaces) and then create a new branch 5.0 for symfony 5.0 support.

Thoughts?
