Tableau Server Upgrades
Windows versions of Tableau Server starting with 2018.2 come with a new web-based server configuration utility called Tableau Services Manager (TSM). Upgrading from 2018.1 or earlier to a newer version will require special steps in order to upgrade successfully. Please see this article for instructions on what has changed to ensure your upgrade experience goes well. The latest releases of Tableau Server 2018.2 and Tableau Server 2018.3 can be found on the Tableau Server release page.
This release contains a critical security update that addresses the Heartbleed security issue.
Heartbleed is a critical security vulnerability in the OpenSSL library (version 1.0.1). OpenSSL is an open source software that is used by many websites and software products, including some Tableau products. The Heartbleed vulnerability allows a remote attacker to read client or server application memory. This can allow for encryption keys to be read, which can enable the decrypting of data obtained by intercepting traffic. For more details on Tableau’s updates for this issue, the Tableau products that are affected, and how to upgrade Tableau, see the Heartbleed Issue Knowledge Base article.
