You can use all the ONLYOFFICE Developer Edition 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 Developer Edition version later, you will need to purchase a new license key. What does the 'simultaneous connections' mean? We specified the maximum number of documents that can be edited at the same time. When the maximum value is reached, each next document will open in read-only mode.
