Hello, I would like to propose a better implementation for the profile properties: lastVisit, firstVisit and previousVisit.
Here is the pull request: https://github.com/apache/unomi/pull/329 Details about the implem are available in the PR description. It's addressing this Unomi tickets: https://issues.apache.org/jira/browse/UNOMI-338 https://issues.apache.org/jira/browse/UNOMI-482 Basically it better handle returning visitor and provide a better handling to respect the events chronology. It also improve the handling in the system of events using date from the past. I know that some peoples are already using such kind of events, so I want to make sure it's suitable for them. Do not hesitate to comment/review/question directly in the pull request thread. Best regards, Kevan.
