Also found that colon ended description and summary. Found a solution for that so now you can use a colon in a description or a summay. Tested with iCloud Apple Calendar, timezones seem to be Iana. Issue with url starting with webcal protocol in stead of http or https, work around is substituting webcal with https:, but solved by change in url check and stricter validation Google Id. * 1.3.0 made time formats of appointment/event times configurable in response to a comment of carolynclarkdfw (@carolynclarkdfw) on the plugin page. Tested with wordpress 5.7 * 1.2.2 added a checkbox to clear cache before expiration in response to a comment of TrojanObelix. * 1.2.1 handle not available DTEND => !isset($e->end) in response to a comment of lillyberger (@lillyberger) on the plugin page, by defaulting $e->end to DTSTART value. tested with https://p24-calendars.icloud.com/holiday/NL_nl.ics * 1.2.0 adjustment not to display time on events that have DTSTART in DATE format instead of DATETIME format after a comment of TrojanObelix. found that date_i18n($format, $timestamp) formats according to the locale, but not the timezone so times and sometimes also dates went wrong, but the newer function wp_date() does, so date_i18n() replaced bij wp_date() (that means wp 5.3.0 is now required). adjusted use of ID's for the events also to work when lineseperator is \n in stead of \r\n after seeing example by of TrojanObelix. Tested with WP 5.5.3. * 1.1.0 parse EXDATE to exclude events from repeat * 1.0.3 trim only "\n\r\0" and first space but keep last space in Description Summary and Location lines. adjustments to correct timezone that is ignored in new datetime when the $time parameter is a UNIX timestamp (e.g. @946684800) * 1.0.2 Adjustments for multiline Description, summary or location. Tested with wp 5.2.1. * 1.0.1 PHP 7.2 deprecated create_function changed in anonymous function in widget_init. Tested with wp 5.0.3 * 1.0.0 first version in WP plugin directory, directory and start php renamed after slug simple-google-icalendar-widget * 0.7.0 BYDAY with DAILY frequency tested. Test code deleted. Present as RC to wordpress. * 0.6.0 BYDAY and BYMONTHDAY work with complete sorting and unifying in MONTH frequency adding class suffixes from setting. * 0.5.0 BYDAY complete first try with sort tested with wordpress 4.8.3 php 7 * 0.3.5 discard non existent days like 31th november first try with byday works als with complete url to ical .ics file. renamed plugin to simple-google-i-calendar-widget and renamed references gcal to ical * 0.3.3 simple repeating events (only full periods) works* 0.7.0 BYDAY with DAILY frequency tested. Test code deleted. Present as RC to wordpress. * 0.2.0 starting work on repeating events * 0.1.0 Added support for start and end time with timezone Changed lay-out of output of teh widget so that is more in line with bootstrap 4 and with the iframe-widget of google a lot of small changes eg: better support for events in a timezone and events that last a whole day. Replace escaped chars for summary, description and location. Refinements in output HTML. renamed starting .php file to simple-google-calendar-widget.php * 0.0 imported V0.7 of NBoehr
