I just installed 14.02 today and we're working with SVN 1.7 and I ran into the following behavior:
1. I refreshed SVN history and accept the default of 500 revisions to cache
2. I then realized 500 is not enough for me, went to the settings and changed it to 1000
3. Then I assumed refreshing the history again, will load the extra 500 revisions I wanted but that wasn't the case
I had to purge the history and reload for the change to take effect, is that by design?
