What problem are you trying to solve?

Is Erlang 28.x compatible with RabbitMQ version 4.1.1? Or, should we upgrade to 27.x?

I read that and the reason I am asking is the site says:
RabbitMQ supports up to two most recent Erlang release series.

Now, it would be version 28 and 27. I just wanted to see if 28 has been evaluated and maybe the site hasn't been updated.

@MarkHackenbergNJR the site is up-to-date. Erlang 28 is not supported by RabbitMQ. It has been evaluated and we have reported a lot of serious breaking changes (namely around TLS, PKI) during the RC stages.

Time will tell if 4.1.x will support Erlang 28, right now all the necessary changes target 4.2.0 #14114 .

Use Erlang 27.x until the site tells you otherwise and never assume that "the site wasn't updated". It is updated nearly every day.

rabbitmq/rabbitmq-website@6b287c4 adds an explicit note to the Erlang version compatibility guide.

The change is already live. Thank you for bringing this up, @MarkHackenbergNJR.
