You can use all the ONLYOFFICE Development Server and On-Premise Server features available at the moment of the purchase for an unlimited period of time, but one year after the purchase date you will no longer be able to get free updates. If you want to update your ONLYOFFICE Development Server or On-Premise Server version later, you will need to purchase a new license key. SaaS Server license must be prolonged each year. What does the 'simultaneous connections' mean? We specified the maximum number of documents that can be edited at the same time.
