I use rev 1.0.1 for my site and edited the date format shown in the header.
In the original the format is US and I want to use localized format (dd month jjjj).
Is the date format in rev 1.2.0 now taken from the localization from WP? This is the only thin form me hesitating to update.
Thank you for your query. If you are in doubt about the setting you can check by downloading the latest version and check it before the update. But in the latest version, we added new features to manage the date format based on the WordPress Settings. So, we think that will not cause the problem for you. Check this screenshot.
You can update theme and check the setting for the date format.
