Nevron Vision for SharePoint 2011 Vol. 1 introduces:

• Parameters and drill down reports - this exciting new feature allows for the development of interactive dashboards and drill down reports. Parameters can be consumed from any expression (see Variables). Parameters can be passed as arguments to the newly added JumpToReport action (see Actions and Drill Down reports). Parameters can also be directly integrated into any SharePoint page (see Custom Parameters with Nevron JavaScript API).
• Ability to connect to SP List and WebPartTable data sources that reside in a StaticSite (fixed site), CurrentSite (dynamic site) and CurrentWeb (dynamic web). The site resolution mode allows you to develop web parts templates that can be directly deployed to production environments without the need to refactor the data source connection.
• Ability to globally (per site-server) configure some user interface elements visibility and some aspects of the web parts behavior through a configuration file. This allows you to fine tune the web parts to perform better and more reliably in the context of your SharePoint environment. See The WebParts Config File  for more info.
• Both Charts and Gauges are now using deferred rendering. This allows for the instant showing of very complex SharePoint pages as the Nevron Web Parts will defer the data aggregation and rendering tasks in separate AJAX requests to the server. This allows for faster data processing that fully utilizes your server capabilities, as separate AJAX requests can be handled by different threads of your server. It also helps the user actually see what is currently being processed, opposed to the immediate rendering mode in which the SharePoint page gets served to the client after all web parts have aggregated the data and rendered the respective visual representation.
• Both Charts and Gauges can now be instructed to automatically refresh themselves at the client side, at user specified intervals of time. This allows for the development of real time dashboards that automatically update themselves at the client side through AJAX, and eliminates the need for manual web page refresh. See Chart Rendering Options  and Gauge Rendering Options for more info.
• Both the Chart and Gauge designers now show the current user, site and web and other info about the context of which they are performing the web part editing.
• A new Image Fill Style has been added to all Fill Style editors. This feature allows you to display image based textures on all charts and gauge elements that have an associated fill style. See Fill Style Editor for more info.
• Ability to connect the Chart and Gauge web parts to other web parts that implement the IWebPartTable interface. This allows you to develop custom web parts that surface any type of data, that cannot be accessed by the currently available data source connections. See Connecting to a Web Part Table for more info.

• The Charts and Gauge control document building and rendering has been completely revised. As a result you should see significant speed improvement.

• All charting types now support automatic data label layout. The data label layout prevents labels from overlapping in both ordinal and scatter charts and works in 2D and 3D appearance modes.

• The axes have been extended to support const lines with texts as well as const ranges.

• All Cartesian axes now support the axis orientation feature.

• The XML formatted text feature is extended to support additional XML tags that allows you to specify the text background and border.

• The Line and Point charting types support options for automatic data resampling. This allows for the visualization of very large datasets.

• The Area, Line, Pie, Error Bar, Step Line, Point and Surface charting types have additional features.

• Legends have additional layout options - added are the Horizontal and Vertical wrap options that allow the legend to automatically wrap the items when the horizontal or vertical space allocated for it is exceeded.

• Chart areas have additional options that allow finer control over the chart aspect in 2D.

Nevron Vision for SharePoint 2011 Vol. 1 fixed the following problems:

• You no longer need to be the site administrator to visually browse the sites, webs, lists and views.
• The web parts are now using only FIPS (stands for "U.S. Government Federal Information Processing Standards") compliant cryptography algorithms. This allows for the safe deployment of Nevron Web Parts to FIPS enabled SharePoint servers.
• The absence of the SPLIT function from the formula engine has been fixed.
