Hi,

Generally we only offer full support for the current version. This is because EO.WebBrowser is based on Google's Chromium engine which is extremely large and very fast evolving. So for example if you see a problem in version 2019 that is rooted in the browser engine and it has already been fixed by the Chromium team in 2020 and the fix is included in our 2020 version, then we won't be able to back port that fix into version 2019. This is because there are numerous changes and fixes (10s of thousands) that are being submitted to Chromium projects between the versions and not only it is not possible for us to back port each one of them, but even if we did manage to do that, it would effectively become the current version. As such all supports/changes are based on the current version.

Thanks!
