How do I update to the newest version of Pirate Quester?

It is stored in the cache of the session in your browser. You need to close all browser windows and go to the site again and it should fetch and cache the new version. It might not work if your browser didn't have time to download the new version before you close the browser. Another option is to force update by hard refreshing on the base address https://piratequester.com/ You hard refresh by pressing Control + F5 at the same time.

That clears the cached version and fetches the new version immediately but if you refresh again it could load the old version from cache still until you reopen the browser.
