That is in the PETSC_VERSION_ macro,

  #define PETSC_VERSION_RELEASE    0

When you use PETSC_VERSION_(3,0,0), you will only match the 3.0.0
release.  People usually do something like

#if PETSC_VERSION_GT(3,0,0) || !PETSC_VERSION_RELEASE
  /* stuff introduced after release-3.0.0 */
#endif

Maybe PETSc should define PETSC_VERSION_GT to facilitate this.
