As many Amiga users know, After OS 3.9 was released around 2000, we were treated with two updates to it, Boing Bag #1 and Boing Bag #2.
While the community and other developers continued updating individual packages, drivers, libraries, etc, you had to piecemeal these together on your own.
Well for the past several years now, there has been a group attempting to take the hard work out of that process for users. The results were the unofficial Boing Bag 3 and 4.
These packages are constantly being upgraded. The current versions now combine 3 an 4 and were updated as recently as just a few months ago (as of this writing in 2017).
You can find their work here: –> link <–
Their website is also the home for BetterWB, a prepackaged Workbench set of tools and utilities, as well as the latest version of Picasso96 software.
It's worth the time to look into it.
