-----------------------------------------------------------------

I do not feel marking things as incompatible, when no compatibility was promised, just to draw the attention is the right approach. But I do not feel too strongly about it. I can move it to incompatible section. BTW do we do this every time an old log or old logs change - say for typo, more complete information etc.?

> I have attached the patch that removes unnecessary information from the log such as "Namesystem." and prefixing file information with "file" and block information with "block" etc.
> On a branch-1 log I saw it reduce the log size by ~10%.
