Hi Lazar Atanasov,
Community edition does not support versionning - you do not have history and page versions. The only solution in this case that I could suggest is using standard edition or upgrading your project to it. Telerik.Versioning and Telerik.Workflow and two class libraries with a quite complex logic in them and some external code could not mimic easily this behavior.

Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
