### Notes

- Panopticon now uses whatever version of Google Chrome you have installed, rather than including its own version, meaning that you benefit from any security updates as soon as they are installed through Google's automatic updates. This means that in order to continue decrypting PDF files, you must have Chrome installed at the default location.
