As our customers know, all our components are designed and built to support SharePoint versions going back to SharePoint 2013.

The minimal .Net Framework requirement for this SharePoint version was 4.5, so this is the framework we had used to build all of our on-premises components.

.Net Framework 4.5 had reached end-of-life more than six years ago, and so most of the 4.6.x versions, so we had decided to upgrade the framework on which our components are built to version 4.8.

This will provide our components with official framework support, more secure libraries, and more programmatic capabilities to build our features on.

So, starting June 1st, 2022 every new release of our components will be built on Microsoft .Net Framework 4.8, it will also be mentioned in each component version history, here on our web site.

By now most of the SP farm servers should've received this framework update by windows updates or installed manually by their farm administrators, but just in case before installing the new component versions, you will need to ensure that .Net framework 4.8 is installed on your farm servers: Determine which framework versions are installed.
