7 * Additional builtin energy functions based on
8 luma instead of brightness
9 * Support for custom energy functions
10 * Functions to read out the energy map
11 * Cancel function to interrupt computations
12 * Additional methods for bias and rigidity masks
13 * Use a single progress instead of several
14 ones when the update is performed in steps
15 * Can handle input buffers non-destructively
18 * Faster rescaling thanks to optimisations in
20 * Spare memory when not using features (e.g. the
24 * The default installation directory is now /usr
26 * Compiling under MinGW now correctly produces a
27 DLL with the default settings
28 * Now it also compiles under MS Visual C++
