[gassan]

Symfony rewritten configs for all own packages to php. it is done here for hwi-oauth too.

PS: Old files not yet removed so that you can compare them before merge.

I think the last commit must be reverted. phpstan moans about security_v5.php (SecurityConfig not exists), old yaml testapp configs are more cleaner.

[gassan]

Cleaned.
I promise to switch tests/App configs to php as soon as symfony delivers its own app config recipes in php. :)
Let's leave the tests/App config files as yaml for now.

Personally I would leave yaml files and recommend php ones, IMHO change is not really significant to force people to change ie routing files etc

Also there is needed change in documentation to recommend php ones as there is either xml or yaml.

[stloyd]

As said, IMHO we should revert yaml routing removal, other are not affecting end users.

After that we can reword changelog cause it will be no more BC break but deprecation.

[gassan]

I wrote whole time about yaml files, but there was no yaml configs in the bundle, all are xml :)

[stloyd]

Merged, thanks @gassan !
