+Bug fixes in 23.0.1
+~~~~~~~~~~~~~~~~~~~
+- The pypi release now uses the labgrid pyserial fork in the form of the 
+  pyserial-labgrid package. This fixes installation with newer versions
+  of pip.
+- Several tests have gained an importorskip() call to skip them if the
+  module is not available.
+- The build-and-release workflow supports building wheels.
+- The markers now are restricted to patterns which won't match WARN,
+  ERROR, INFO and similar log notifiers.
