In the Tableau 9.3.10, 10.0.4, and 10.1.2 updates, data from Excel connections are inadvertently being treated as case-sensitive, causing many existing views to return incorrectly sorted data. 9.3.10 is removed from the download site. This change will be reverted and thus repaired in 9.3.11, 10.0.5, and 10.1.3.
Release Notes for Tableau 9.3.10 Note: Tableau Desktop customers in environments with Product Updates enabled will be prompted to upgrade a few days after a maintenance release is made available. For more information, see the Tableau Knowledge Base.
