Blog Summary block 30 item limit increase

I will be converting my client's site to 7.1 next week. She has a substantial blog content library that we have broken into Summary blocks in order to show them all. We are wondering if that changes with 7.1 or if there is still a limit? We don't want to go through and update the URLs for the blogs as they are already linked elsewhere. 

Have a look at Squarewebites plugins (link in my signature), they have plugins for doing exactly this and more!
