wq.build 1.3.0b1 is the beta of the upcoming 1.3 version of wq.build (formerly wq.core). The new module combines the wq core command as well as the (non-deprecated) commands from wq.app.build into a single module. See the release notes for wq.app 1.3 beta for more details.

In general it makes sense to just install the latest wq package, which specifies wq.build as a dependency. The upgrade from wq 1.2 to 1.3 will generally just work, though the old wq.core package will remain installed. This is generally harmless, but if you uninstall wq.core after upgrading, you may experience issues with the wq command. If this happens, try uninstalling then reinstalling with these commands:

python3 -m pip uninstall wq.core wq.start
python3 -m pip uninstall wq.build
python3 -m pip install wq==1.3.0b1
