From the FAQ:
The Patreon version of Sileo receives new content a month in advance of the Public release. Otherwise, both versions are typically exactly the same and usually receive new features, bug fixes and other improvements at the same time. The free Public Version is completely unrestricted and being updated every single month with great new content to enjoy!
