Oracle released the new Version of exachk. The version is shown as 18.2.0_2018052018 so far so good. The next sentence in the Note is: „What’s new in exachk 220.127.116.11.4 may be found in the „What’s New in 18.104.22.168.4″ section of the User’s Guide available here..“
The new Release model from Oracle is really confusing. From my point of view it makes no sense that you download a Version as 18.2.0 and then the Documentation has a Version 22.214.171.124.4.
