    M ./src/meep/vec.hpp +24

Mon Mar 27 22:39:25 EST 2006  [e-mail]
  * backwards-incompatible change: re-order the arguments for all field_function and and field_rfunction arguments so that the callback void* goes immediately after the callback function; this is to enable these functions to be called from the libctl interface (which requires that SWIG be able to recognize the arguments as a group)

Tue Nov  8 18:33:07 EST 2005  [e-mail]
  * Less aggressive compiler flags (FIXME: why does -fstrict-aliasing cause 'make check' to fail with g++ 3.3.5?  Is this a compiler bug, or a Meep bug?)
