The documentation has received a massive update (as the title would imply) with the most changes happening in the functions and signals section. Though there were improvements all over the place.
Functions and signals both now have direct links to their official Steamworks SDK documentation counter-parts; so you can click the link and see Valve's examples as well as further information about each function or callback / call result. Each also has a toggle for GDscript and C#. C# users can now see the specific integer types used for arguments and return values.
The whole documentation site has been mirrored on CoaguCo's site and is also now exported from that copy due to Github only allowing static pages.
Next up is a big update to the module itself!
