With Spring '19 around the corner, I decided to set up a pre-release org and upgraded my client to 45.x. After playing around a bit, I then went back to work on my actual work projects, and came across an error:
ERROR: The configured apiVersion 45.0 is not supported for this org. The max apiVersion is 44.0.
Now, I'm not able to do any work in my sandbox! Is there a way I can use the correct API version in each project? For now, I have to switch between installing salesforcedx@latest and salesforcedx@pre-release each time I want to switch modes.
