[Compile with older JasperReports version from Jaspersoft Studio]

The above instructions are not current. I installed latest Studio (6.15) on my new dev laptop and need to compile reports to version 6.6.0 for compatibility with prior reports and website. However, the interface for this is different in 6.15. I can get to the 'Manage JasperReports Versions' link but the dialog window asks for a URL or Path to the version I wish to use, rather than choosing from a list of versions. Is there a repository of past versions I can get links to, and what file exactly am I linking to?

Thanks in advance for the support.

[Math Calculation in Variable expression]

Is there a reference document that lists available math expressions and their usage?
