  1. It’s not just new features being added, but some old ones dropped as well. The one that comes to mind for me is the X font server capability. Nowadays all GUI apps do their font handling client side (e.g. using FreeType and Fontconfig). There is still the concept of “X fonts”, and the display server still supports text-drawing calls. But I suspect these don’t get a lot of use these days.

  2. 1:56 Best to distinguish between the X protocol (or perhaps “protocol family”) versus XLib, which is just one implementation. Remember there is at least one other popular implementation, XCB, which gets rid of various responsiveness/performance bottlenecks in XLib, while still implementing exactly the same protocol.
