Report Builder 2016
By the end of 2016 Microsoft rebranded Report Builder 3.0 as Microsoft SQL Server 2016 Report Builder. It can freely downloaded from the following link https://www.microsoft.com/en-us/download/details.aspx?id=53613
Note: on version v17.4 the Paperless was upgraded to handle SSRS reports created with Report Builder 2016.
A new set of report templates with names ending in "SQL2016.rdl" will be automatically added to the RDF folder the first time the app runs.
Note: the references to each individual report file will need to be manually adjusted of each module.
