* fix subtensor bug(report RP, fix PL) TODO BETTER DESCRIPTION! a7be89231eb26f7a39ab5448ef4abf90a6c0d529
If you have updated to 0.5rc1, you are highly encouraged to update to If you have updated to 0.5rc1, you are highly encouraged to update to
0.5rc2. There is more bug fix and speed uptimization! But there is 0.5rc2. There are more bug fixes and speed uptimization! But there is
also a small new interface change about sum of [u]int* dtype. also a small new interface change about sum of [u]int* dtype.
