General question about supporting new browser versions
One answer
For Chrome
Chrome does not provide an ESR release - they typically provide a new release every 6 weeks. To support this, CLM will regularly support the current release of Chrome and the two prior versions. The versions supported for any particular CLM release are based on the Chrome versions available at the time of the CLM GAFor Firefox (ESR), I believe that's the latest two versions, and the same goes to IE.
