2.1.0

Greatly improved factoring speed above 50 bits, via ECM. The factoring interface has a new final argument to indicate whether you expect the number to have arbitrary size factors, rather than all large factors - you can continue to use the interface without any change from the previous release, since this new argument has a default value (true by default).

2.0.0

Changed the API function factorize_to_vector to no longer return a std::vector. Instead it is renamed to factorize and now takes a std::vector reference. This release is otherwise nearly identical to v1.0.0

1.0.0

Formal github release. Although the API was already stable and the readme had already announced the library is in release state, this v1.0.0 github release provides semantic versioning and source code archives.
