Migration v2 → v3

Version 3.x has few changes compared to previous version.

Breaking changes

setLogger

Client->setLogger(LoggerInterface $logger): void
Server->setLogger(LoggerInterface $logger): void
MiddlewareHandler->setLogger(LoggerInterface $logger): void

These methods now return void instead of self. This means method return can not be chained.

The change makes v3 compliant with psr/log v3.

receive

Client->receive(): Message

The method no longer has Message|null as return type. It never returned null before, so only the method profile has changed.

Extending

When extending classes in this repo, you might need to implement typed properties in child class.
