Converter - type selection - subdir conversion - htm extension Gemini - index.gmi - topics and latest - gmi.atom feed Add pull (http(s)) operation - peers.pub.conf and peers.priv.conf HTML5 format & fixes by Novaburst Phony target (thanks Gergely) May Basic unit renamed from Note to Text. New modular text-parser, internal to Logarion, for generic notation parsing. The default input format is now a much plainer text. Logarion created texts have part of the UUID in filename. Logarion's index re-written in Messagepack format. Removed `indices` command. They are generated during `convert`.
