15.2.0 supports a wide array of newer browsers that your users may run to access your iMIS websites. iMIS iParts support Firefox 6 and Internet Explorer 8 and 9 (IE8 compatibility mode for non-iPart web views). In addition, iMIS iParts work with Chrome and Safari (for MacOS).

Microsoft Framework 4.0
15.2.0 uses Microsoft Framework 4.0, which is the latest full release of ASP.NET technology. Its benefits include improvements to stability, performance, and usability.
The new framework supports recovery from pages with malfunctioning iParts. For example, if someone accidentally deleted the content item for an iPart, the page can now load with a placeholder (“The iPart cannot be loaded”), which lets you edit the page to delete the offending iPart reference.
SQL Server 2008 R2
15.2.0 supports Microsoft SQL Server and Express Edition 2008 SP2 and now 2008 R2 (both 32-bit and 64-bit). Note that 2008 R2 is not backwards compatible. SQL Server 2005 SP3 remains supported for upgrades only.
