Newer Stable Versions - Linux Mint 17.3 Repository

New to Linux Mint 17.3 from Win7. My biggest problem is finding professional software that is current. LM repository currently has RNB 1.4.0-1 from 04-2012. I am interested in your software and development is apparently active, unlike some software reviewed. Why can we not get more current versions for download into the repository?

I am dismayed by the whole Linux/Ubuntu community saying that everything is free. Nothing is free! I want better software in a secure and private environment. Coming for the MS world, everybody paid for everything yearly. I personally believe that if I take 1/2 what I used to pay every year and distribute it to the software I use, I am getting a bargain and I encourage every user in the Linux community to support at least 6 of their most used softwares after supporting their distro. That would be min $60 to $100 a year into the development of OS software by a growing number of users. (Thanks to MS Win10 - spyware posing as an OSys.)

Can we expect to see more current stable versions of RNB in the Linux Mint and Ubuntu repositories any time soon? I just want software proven to be stable on my OSys.
