Major changes

• Migration to System.Text.Json
• More extensible GridViewDataSet
  • the refactoring should be mostly compatible, if you didn't write your own DataPager and encounter issues, please get in touch with us
  • it is now possible to use GridView and DataPager which load data using staticCommands
  • it is now possible to use token-based paging instead of just page index
  • it is now possible to use custom sorting options which limit what columns can be used for sorting
• DataContext and DataSource properties support resource binding
  • it makes it possible to show server-rendered collections without also sending all of the data in JSON, and without including any knockout data-bind attributes in the HTML

We'll have more polished release notes with the 5.0.0 stable version
