Thanks to everybody who helped testing all release candidates in the past months - it has been a long time!
Since we added so many features we decided to bump the minor version of the calendar.
1.6.0 will come soon!
Here is the most likely last release candidate: https://github.com/owncloud/calendar/pull/921#issuecomment-421909435
We plan to announce the final version during the ownCloud Conference 2018 this week!
Happy to meet you there the next days!
