	- Tidied-up source tree
	- MPI interface (optional)
	- faster incrementation (++-operator)
	- New version numbering policy

0.5
	- improved source tree layout
	- sign representation simplified
	- ++ and -- operators added to "real" interface.
	- New simple functions that come in very handy, e.g. for comparison of absolute values.
	- significant improvement of log performance.
	- improvements to trigonometric functions
	- bugfixes: boolean arithmetic, multiplication

0.4.2:
	- Bugfix in Karatsuba multiplication

0.4.1:
	- Added "Changelog"
	- Added benchmarking module
	- configure now requires __APMATH_TESTPROGRAM instead of __APMATH_CONFIGURATION_PROGRAM
	- Added "min_precision" & "max_precision" to precision_control
	- Smarter memory management in multiplication (speed up).
	- "random_number_generator" is renamed to "random".
	- "div_2_pow/mul_2_pow" are more robust.
