EPM 188.8.131.52 is out and includes installers for Linux as well as MS Windows. This is the one many organizations have been waiting for.
Time to spin up a new sandbox and take it for a test drive!
Edit: As of this writing, the 11.2.x documentation portal was last updated in May 2020. While it is still 11.2.1-centric, there is a comment within the Installation Readme stating that Microsoft IE11 will not be supported in 11.2.2. So we'll want to carefully review the 11.2.2 certification matrix once it is published. The path forward looks to be MS Edge, Google Chrome and Firefox. I'll publish a separate post on this topic once Oracle has updated their documentation.
