This diff is too big for us to render.

Hello.

My goal is to see difference between two branches.
https://bitbucket.org/mebelrama/complex/compare/release..master\\
There are near 50 commits. Earlier Bitbucket was able to draw diff between them. But since today there is a message "This diff is too big for us to render." for all diffs even those with 1 line being changed. Could you please fix this issue.
This feature is very important for me while doing pre-release code review.
Thanks in advance
