I have the stable channel 11.02 upgrade but BxTimelineTemplate.php file is not exactly same as I see.

this part does not exist in my file if I also put this part as a whole it breaks the site, may be there is another beta version of the file??:

'more' => $iAttachmentsTotal - $iAttachmentsShow
                ));
        }
        return array(
            'style_prefix' => $sStylePrefix,
            'bx_if:show_title' => array(
                'condition' => !empty($sTitle),
                'content' => array(
                    'style_prefix' => $sStylePrefix,
                    'title' => $sTitle,
                )
            ),
            'bx_if:show_content' => array(
                'condition' => !empty($sText),
                'content' => array(
                    'style_prefix' => $sStylePrefix,
                    'item_content' => $sText
                )
