Following up to the post in the General Discussion about seeing versions/issues in both the change log and road map (http://www.mantisbt.org/forums/viewtopic.php?f=2&t=6968), below is an easy solution that adds "Release Pending" to versions in the change log that are not yet released. These modifications are made to the function print_version_header( $p_version_id ) in mantis/changelog_page.php Of course, "Release Pending" should be made language-specific using lang_get().
// Get the release status of each version
$my_released = version_get_field( $p_version_id, 'released' );
//existing code (1.1.4)
$t_release_title = string_display( $t_project_name ) . ' - ' . string_display( $t_version_name );
// If version is not released, append "Release Pending" to the title
if (!$my_released) {
$t_release_title .= " (Release Pending)";
}
