Why

How

[ostrolucky]

doctrine/orm, symfony/doctrine-bridge needs to support it first

[greg0ire]

For ORM it's done but not released yet.

[kaskader201]

ORM 3.3.1 has been released and there is support for doctrine/persistence ^4.0

[ostrolucky]

Ok. Now symfony/doctrine-bridge

[greg0ire]

@kaskader201 that's cause it was contributed to 3.4.x, cause this is not a bugfix.

[greg0ire]

Misread as "and there is no support"… there is support indeed, I accidentally released this as 3.3.1, so yeah, this blocker is removed 🤦

[greg0ire]

My attempt: symfony/symfony#59575

[ajgarlag]

New symfony/doctrine-bridge versions compatible with doctrine/persistence 4 have been released
