Blog list moved to a standalone skin module + it is disabled by default in the conf. Too many people seem to be confused about having this on their blog template. Enabling is a easy as setting $display_blog_list = 1; at any time (main switch in b2evo_conf.php).
New front page for ‘my blogs’ explaining a little more what’s going on there ;)
Cross posting among multiple blogs has been disabled by default. Again too many people seem to be confused about this. Enabling is as easy as setting $allow_cross_posting = 2; in b2evo_conf.php.
