Are events now stored in wp_posts instead of wp_event_list?

This is largely correct with 2 exceptions / additions:

1) It wasn’t the last update, but update 0.8.0 from 2018-01-27, and

2) There is a migration script that is supposed to work, but doesn’t always work.

The log from version 0.8.0 says:

“Attention:
The modifications in this versions are huge. This modifications will bring some huge improvements and is a good basis for future improvements (e.g. permalinks).
But inspite of a lot testing it doesn’t eliminate any possibility for some regressions or problems during update process to the new data structure.

Due to this there are some steps you should consider before and after this upgrade:

* have a look at the support forum if there are issues reported with the new version, and wait with the upgrade until these are solved
* if you have a big productive site probably do not upgrade in the first days
* have a look at the PHP error file after upgrade, the upgrade function will write some informations regarding the upgrade process to this file
* check your shortcodes and widget and do the required manual changes provided below
* check your events, the event categories and the event output on the frontpage after the upgrade
* please report problems with the upgrade or issues/regressions after the upgrade in the support forum or on github”
