We have a development partner that create a custom component for us. It is using an older version of Telerik. What would be the recommended version to use now. We are looking to move to an Azure environment using containers. Below is the version information of the DLL.
Thanks!
Version information
Product Name - Telerik.Web.UIProduct Version - 2015.1.401.45
Original filename - Telerik.Web.UI.dll
We always recommend using the latest version since it is the only one to support the latest browser versions, it includes the latest fixes, security and accessibility improvements.
On a side note, 2015.1.401.45 is vulnerable to CVE-2019-18935) and you must upgrade to at least version 2020.1.114 to prevent the vulnerability. More information is available at https://docs.telerik.com/devtools/aspnet-ajax/knowledge-base/common-allows-javascriptserializer-deserialization.
