We are currently on version 184.108.40.206 and were told that an issue we reported to Oracle is being fixed in version 220.127.116.11. I was told that currently only 18.104.22.168 is available to install. When is the 22.214.171.124 release date or where can I find the RUP schedule for future releases?
126.96.36.199 was released in mid of Oct, 2019. if you have trouble to download, please ask support.
as for 188.8.131.52, the estimated release time is mid of Jan, 2020 (one RUP release usually comes out after three sprints), however, the date may change due to different circumstance. we will announce in ARU (Automated Release Updates) when the release is available.
Let us know if you have further questions.
