Three new visualizations
The new gauge types are the circular gauge, the multi-level gauge, and the arc gauge. These gauges have formatting properties to set minimum and maximum values, colors for value ranges, whether the value is displayed, and if so the number of decimal places and a suffix string such as the % sign.
Ad Hoc visualization selector
This UI element has been updated to choose or switch between visualizations more easily. The visualization selector now lets you choose crosstab or table, and the chart selection includes a sidebar for chart categories. In addition, the visualization mode toolbar drop-list is replaced with a visualization selector button.
New color picker dialog
The Ad Hoc Designer and Dashboard Designer have a new color picker interface for specifying colors to match any palette where visualizations are embedded. The default color selections are expanded, and custom colors may be specified precisely with HEX or RGB entry options.
Colors in Ad Hoc charts
There are several new features in the Ad Hoc Designer that allow greater customization of chart colors. New UI properties allow the user to set the series color, the plot color, and the background color in charts that allow it.
Distinct values in Ad Hoc tables
Tables often contain columns that have duplicate values in many rows, making it difficult to find relevant data. The new distinct values selector in the Ad Hoc Designer hides the duplicate rows and makes tables shorter and easier to read. Note that tables with a totals row will not recalculate the total values when duplicate rows are hidden.
Referential Integrity for Domains
New configuration settings let you adjust how strictly Ad Hoc views and reports are checked against their underlying Domain. By default, fields and measures in a view or report that do not exist in the Domain will cause an error upon opening. Administrators can adjust the level of referential integrity to allow opening views and reports when Domain security causes missing items.
This release of JasperReports Server updates its use of cryptographic keys, for example to encrypt user passwords internally. All keys are now generated and managed in a single keystore for consistency. Keys used for encrypting export catalogs from older versions of the server have new procedures and user interface for importing into this version of the server. For more details, see the JasperReports Server Security Guide.
Update to Log4j 2
The logging service now relies on the updated Apache Log4j 2. This upgrade provides higher performance of the loggers and thus less overhead for JasperReports Server. If you have custom loggers, you will need to update their definitions using the new syntax.
JasperReports Server runs with Java 8 and Java 11 for certain platforms, see the Platform Support document for more details.
