# 0.4.1 - Fixed segmentation fault if mmap don't work and fallback to malloc in that case. # 0.4.0 - The asynchronous transfer API's and control has been rewritten. Please use new_control_in/out instead of low level new_control. - Memory leaks fixed in asynchronous transfers. - Timeout added to bulk block transfers. HGowever please use the asynchronous API's instead see example/stm32.rs how to use the API. # 0.3.0 - Change ControlTransfer API and setup an mmap fort control transfers. - get_descriptor_string variants now return error on fails. # 0.2.4 - Fix some of the unsafe memory leaks - Use mmap for control channel. - Remove some code better panic that seg fault.
