v1.2.2
Adds miniwdl run --env X to pass through environment variable X to the environment of all tasks, or --env X=foo to set X outright. (Can be supplied multiple times for different variables)
This is a non-standard side channel likely to cause portability problems for WDL tasks relying on it. It should be used only in certain circumstances where portability isn't a priority, for example passing through auth credentials for platform-specific APIs. Otherwise, it's usually better to pass explicit WDL inputs (and if necessary, set environment variables in the command script).
