Hello 👋

With symfony 3.4 no longer maintained, has there been any work towards symfony 4 ?

I found this subject about it, though I can't find anything about it afterwards.

Hello @PieterjanMontens,

An upgrade to SF4 is planned for the end of the first quarter.

Thanks for the update.

I opted for a progressive migration towards SF4 on the fork I'm working on ( https://github.com/betagouv/itou-cocorico/ ) while trying to document changes as I go.

In short:

• switched assetic for webpack (config file)
• some minor refactoring (deprecated php code)
• JS refactoring (because webpack / encore)
• Some JS libraries provided by node instead of composer
• Managed to make it work with mostly unpinned (and up to date) dependencies : https://github.com/betagouv/itou-cocorico/blob/master/composer.json

Switch to 4.0 is close (not looking forward to switching to Flex) and most depreciation alerts are from dependencies, not from the application code.
