+  In June 2025, Plotly made significant updates to the kaleido package with the 1.0.0
+  release by removing Google Chrome code.  Now, users will need to have Google Chrome
+  installed in directories specified in this Plotly documentation (based on operating
+  system):
+
+https://plotly.com/python/static-image-export/
+
+The METplotpy code downloads Chrome at runtime by invoking the kaleido.get_chrome_sync()
+method call.
+
+If users do not wish to have Chrome downloaded at run time and already have Chrome installed
+in one of the expected locations (specified in the Plotly link above), then the PRE_LOAD_CHROME environment variable
+will need to be set to 'True' (case insensitive string).

+Refer to the Kaleido  README for more information on the changes:
