Added next option to the show_recurrences parameter, allowing you to display only the next available occurrence that falls within the date range, rather than all available recurrences of that event.
Added support for MySQL 5.7 ONLY_FULL_GROUP_BY mode.
Added 'calendar:event_ampm_match' conditional to Calendar:Events tag and custom field display in Channel:Entries. Helps you display event dates/times like '4:00 - 6:30pm' rather than '4:00pm - 6:30pm'.
Fixed a bug where ICS Location and Description fields would not export correctly if you only had them assigned to a field group and not each directly assigned to the channel.
Fixed a bug where if a multi-day event started before the beginning of a week, the Calendar:Week tag would not include its occurrence in the total events count.
