Updating supported browser versions
The list of supported web browser versions was known and tested at the time of release. However, new web browser versions may have been released since that time that are also supported but have not been subjected to testing. As a result, the Classic client may display a 'browser version not supported' warning contrary to this list, or it may display no warning even though the browser version you use is not listed.
