I have just upgrade to Calendar 2.0.5 and I used to have a template that generated a list of events sorted by month using the {display_each_month} loop within {exp:calendar:cal} tag. Now that the cal tag no longer exists I can't figure out how to do this...
<ul>
{exp:calendar:cal sort="asc" dynamic="no" calendar_name="events" date_range_start="today" show_months="3" pad_short_weeks="n"}
{display_each_month} <br/>
<p><strong>{date format="%F"}</strong></p>
{if month_event_total == "0"}<li>There are no events scheduled for {date format="%F"}.</li>{/if}
{events}
<li><strong>{event_start_date format="%d"}</strong> - {event_title}</li>
{/events}
{/display_each_month}
{/exp:calendar:cal}
