 	<li><strong>Compress files</strong>: By default, ZeeCrypt uses a zip file with no compression to quickly merge files together when encrypting multiple files. If you would like to compress these files, however, simply check this box and the standard Deflate compression algorithm will be applied during encryption.</li>
 	<li><strong>Deniability</strong>: ZeeCrypt volumes typically follow an easily recognizable header format. However, if you want to hide the fact that you are encrypting your files, enabling this option will provide you with plausible deniability. The output volume will be indistinguishable from a stream of random bytes, and no one can prove it is a volume without the correct password. This can be useful in an authoritarian country where the only way to transport your files safely is if they don't "exist" in the first place. Keep in mind that this mode slows down encryption and decryption speeds, requires you to manually rename the volume afterward, renders comments useless, and also voids the extra security precautions of the paranoid mode, so you should only use it if absolutely necessary. <strong>If you've never heard of plausible deniability, this feature is not for you.</strong></li>
 	<li><strong>Recursively</strong>: If you want to encrypt and/or decrypt a large set of files individually, this option will tell ZeeCrypt to go through every recursive file that you drop in and encrypt/decrypt it separately. This is useful, for example, if you are encrypting thousands of large documents and want to be able to decrypt any one of them in particular without having to download and decrypt the entire set of documents. <strong>Keep in mind that this is a very complex feature that should only be used if you know what you are doing.</strong></li>
+	<li><strong>Explorer integration</strong>: If you installed ZeeCrypt with the MSI installer, right-clicking a file or folder shows an "Open with ZeeCrypt" entry. ZeeCrypt automatically detects whether to encrypt or decrypt based on what you open, so there's no separate Encrypt/Decrypt option to pick - just right-click and go. Selecting multiple files or folders and right-clicking opens them all in one window.</li>
+	<li><strong>Update checker</strong>: Click the version number at the bottom-right of the window to check for a new release. Nothing happens automatically - checking only happens when you click, and if an update is found, you'll see the release notes with an "Update Now" button rather than anything downloading or installing on its own. The downloaded update is verified against its published checksum before it replaces the running executable.</li>
