From my experience for the most part it what you see is what your getting. Things are almost never added last minute with zero testing. Sometimes something might get removed last min after testing the "live patch" on CTE.

This is likely true of the content itself, but these particular CTE patchnotes are a bit rough, to say the least. Typos, repeated sections, and I either know of directly, or have heard solid rumours of things that will also be in the patch that aren't listed there.
