* Support compilation with precompiled headers with Make and GCC or CLang.
* Change include of systemc instead of systemc.h (#4622) (#4623). [Chih-Mao Chen]
This may require that SystemC programs add 'using namespace sc_core', 'using namespace sc_dt'.
* Optimize timing-delayed queue (#4584). [qrqiuren]
