In some cases, when connected to a Tableau Server data source that contains averaged calculated fields, the averaged values would not match what they were in earlier versions of Tableau. This issue was because Tableau 8.0 included null values that were not previously included in the average calculation. The null values are no longer included in this type of calculation.
Annotations placed on top of marks would no longer trigger hover actions as they did in earlier versions.
String columns with UTF-8 encoding in Vertica databases were being interpreted as ANSI/MBCS character strings and were not displaying correctly.
Some bitmap images on dashboards would cause the application to exit with a Runtime Error because Tableau would not recognize if the image did not resize correctly.
Adding very large background images could cause the application to exit. If the background image cannot be rendered, a message now displays indicating that the image is too large.
Opening a workbook that uses an SSL Generic ODBC connection to a PostgreSQL database would fail with a no password supplied error instead of prompting for credentials.
Added support for connecting to Sybase Adaptive Server Enterprise (ASE).
It was possible for an extract refresh to succeed even though the refresh query failed. This resulted in an empty extract (zero records). An error message has been added to indicate that the refresh didn't succeed and the original extract was not refreshed.
Added support for connecting to the Amazon Redshift database.
The data source connection list at the top of the Data window would not show a scroll bar when there were more than 30 connections in the workbook.
Added support for the POWER (float, integer) function when connecting using the Generic ODBC connector
Font styles (bold, italic, etc.) for mark labels were not preserved when exporting an image to Enhanced Metafile (.emf) format.
Copying and pasting images or exporting an image as an Enhanced Metafile (.emf) would sometimes clip mark labels or axis labels at the end of the image.
Editing a Tableau Server data source in a workbook that has one or more User Filters would fail with the error Commit called on a nested editor.
Computing totals on calculated fields that included columns from a blended data source would cause and error or cause the application to exit.
Loading views that connect to Oracle could sometimes result in an Identifier too long error. Connections to Oracle databases were sometimes creating temporary tables and indexes to help with filtering and the index names could incorrectly exceed the 30 character limit Oracle has for names.
An out of memory error message was incorrectly displaying when creating an extract with large data sets.
Copying and pasting data into Tableau (clipboard data source) would not work properly if the data includes an extra empty row at the top of the table.
