1. Are we still producing PDF documentation? The last one I have, was from 2013, JIPrologRefManual.pdf. Or is it all wiki-based and online, at this point?
2. Is it all open-source now? Or is there a separate commercial version? I'd like to upgrade, if it includes the PDF documentation.
1. The most recent version, is at https://github.com/jiprolog/jiprolog/releases/tag/22.214.171.124. It contains a .jar. If you want some of the other tools, like JIPConsole, you need to link to the previous version, https://github.com/jiprolog/jiprolog/releases/tag/126.96.36.199. That contains a Zip, which contains the console jar, as well as the main JiProlog jar for that version.
2. Thanks for continuing this project.
