#2784 fixed compatibility for Symfony 4.3 in master / 2.5. This is basically the same but without bumping the dependencies.

Together with #2920 (and maybe more to do in #2911) this should allow full Symfony 4.3 compatibility in 2.4.

Okay, this needs more work. 😆 Fixed.

[teohhanhui]

We will need to be careful when merging this into master. Haha...

[dunglas]

I'll let you do :p

Since symfony/messenger v4.3 introduces BC, is v4.2 still supported?

[teohhanhui]

@karser Both are supported. As always, if we broke anything, please let us know.

Hi, it seems to be related. During my composer req messenger (project based on api-pack), I get this error so I. can't install messenger component.

 Problem 1
    - Conclusion: don't install symfony/messenger v4.3.2
    - Conclusion: don't install symfony/messenger v4.3.1
    - symfony/messenger v4.3.0 conflicts with api-platform/core[v2.4.5].
    - symfony/messenger v4.3.0 conflicts with api-platform/core[v2.4.5].
    - symfony/messenger v4.3.0 conflicts with api-platform/core[v2.4.5].
    - Installation request for symfony/messenger 4.3.* -> satisfiable by symfony/messenger[v4.3.0, v4.3.1, v4.3.2].
    - Installation request for api-platform/core (locked at v2.4.5) -> satisfiable by api-platform/core[v2.4.5].

@teqno this PR is not released yet. api-platform v2.4.5 conflicts with symfony/messenger: >=4.3.

Is there a workaround for installing symfony/messenger ?

[soyuka]

Force core to use our 2.4 branch directly? Or else you could stay with <4.3 everywhere and it should work!

[fri0z]

If I understand correctly the fix in the 2.4 branch no. https://github.com/api-platform/core/blob/2.4/composer.json#L76

[teohhanhui]

@fri0z Use "api-platform/core": "2.4.x-dev" in your composer.json

[fri0z]

@teohhanhui Thanks, but i solved, downgrading symfony to 4.2

@teohhanhui Thanks!
I removed "api-platform/api-pack" from my composer.json then I add "api-platform/core": "2.4.x-dev" and there is no more conflict.
I manually add the packages which have been removed because of api-pack:

        "phpdocumentor/reflection-common": "^1.0.1",
        "phpdocumentor/reflection-docblock": "^4.3.1",
        "phpdocumentor/type-resolver": "^0.4.0",
        "symfony/asset": "^4.3",
        "symfony/expression-language": "^4.3",
        "symfony/validator": "^4.3",
        "webmozart/assert": "^1.4.0"

Thanks for your help and this awesome api-platform.
