Version 3.6 of amr-events is available for download.
It should be used with the free listing part: amr-ical-events-list version 4.30. Several improvements have been made in the way that event meta data, taxonomies etc were being retrieved. This has reduced the database queries made when producing an event list from events in wordpress.
If you have a fairly recent version, and your access to the automated updates from icalevents is still current, then it should appear in the normal wordpress plugin updates.
