Change menu block name "Account menu" to user's realname

Actually it is possible.

If someone is interested, add this code to your custom theme's template.php:

<?php
function MYTHEMENAME_preprocess_block(&$vars) {
  if ($vars['block']->delta == 'accountmenu') {
    $user = $vars['user'];
    if ($user->uid) {
      $name = function_exists('realname_user_page_title') ? realname_user_page_title($user) : $user->name;
      $vars['block']->subject = check_plain($name);
    }
  }
}
?>

@maintainer: why not adding a default version of this function (accountmenu_preprocess_block) to the module?

Sorry for the late feedback.
It works, thanks!

Can we expect a new official release soon?

This is committed, isn't it? Shouldn't it be marked as fixed then?

Waiting for a new official release, please!

Great, thanks!
