Adam Buyer, project leader at B1 says:
“Every new version of the B1 Free Archiver has many valuable updates. The 0.5 version is important, because of smart compression. The goal for every archiver is not only to provide users with higher compression level, but also to complete processes as fast as possible. Time is the most valuable resource and nobody likes to wait too long. I think the B1 Free Archiver v.0.5 will satisfy the demands of all our users.”

“Since last release we have received a lot of grateful letters from our users. They highly appreciate our user-friendly interface and minimalistic design. That’s really inspiring. Also we received some very important suggestions about functionality and features of B1. We corrected our road-map for next versions to meet most demanded requests. I want to thank everyone who send letters to [email protected] and I promise that we continue to listen and analyze all the feedbacks.”
