<li>Clarified that <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> does <em>not</em> have to be invoked on startup for all channels, as it will be automatically triggered (only for channels that need catching up) by a set of <a href="/constructor/updateChannelTooLong">updateChannelTooLong</a> updates that will be returned by <a href="/method/updates.getDifference">updates.getDifference</a> (that <em>does</em> need to be called on startup). </li>
