The Daml version stated in the `daml.yaml` file is strangely overridden - why?

What does this warning mean? How can I go back to normal behavior?

Warning: Using SDK version 2.3.4 from DAML_SDK_VERSION enviroment variable instead of SDK version 2.4.0 from daml.yaml config file.

Needless to say that when I try to print out $DAML_SDK_VERSION I get nothing.

@gyorgybalazsi Exactly what kind of operation are you performing when you receive this message?

Building a package with ‘daml build’.

I’ve found out the reason for this, I’ve specified a nonexistent SDK version in the daml.yaml file.

Indeed, 2.4.0 is not out yet.

For the record, 2.4.0 is out now.

Yes, thank you!
