Opening a project that previously compiled in 2.2 in the new 3.0 release.
Clean and build project yeilds a bunch of errors, namely typedefs for uint8 etc. not found in cytypes.h.
device.h header file has an include for <project.h> where all of the other includes are called, including cytypes.
Right clicking on the #include <project.h> and selecting "Go To Implementation" gives the following cosole message:
"Unable to find implementation for . It may be in a library for which no source is available."
Thus it would appear that the new PSoC Creator 3.0 is not finding the include files as necessary.
