Apache Tomcat was upgraded to 7.0.75. This upgrade fixes a potential vulnerability in Tomcat: CVE-2016-8745
When you used a published data source that was connected live to an underlying table, and additional columns were added to that underlying table, refreshing the data source in Tableau Desktop would not update the data pane with the new columns for an extended period of time. Due to potential performance trade-offs of extra queries for column metadata, the fix is hidden behind a Tableau Server configuration setting that must be toggled on.
In some cases, when you interacted with a small multiples view containing pie charts in Tableau Server, visual artifacts would appear in the browser.
When viewing an embedded view, or using the share link, and downloading the view to PDF from Tableau Server, the Download PDF dialog sometimes did not appear, or was cut off, unless you zoomed out in the browser.
In some cases, workbooks connected to a Microsoft Excel data source would fail to load with an internal error.
When you had a stepped color legend in a published Tableau Server view, zooming out in a browser would introduce an additional color step in the legend (usually white or black).
In Tableau Server, the 'Live/Last extract' column in a workbook's data sources page failed to update when you refreshed the workbook's extracts in Tableau Desktop and republished the workbook.
When switching between custom views in Tableau Server, incorrect data would sometimes be returned if the views only differed by parameter selection and the parameter was being referenced in a calculated field used as a data source filter.
In some cases, when you published a small multiples view with pie marks to Tableau Server, the marks became unclickable in a browser. The result, most of the time, was that tooltips could not be exposed.
In a small number of scenarios, sometimes involving level of detail calculations, extract query performance became significantly worse after upgrading to Tableau 9.3 or higher.
In Tableau Server, when you loaded a view using a URL parameter, and the same parameter was also used in custom SQL for the workbook's data source, the view would sometimes fail to show the correct data for the specified parameter value unless ':refresh=yes' was also appended to the URL.
In Tableau Server, adjusting a range of dates filter using the date picker would reset any previous time selection if there was a time part associated with the dates.
