Changelog

Dated, specific, every release. There is no public roadmap — see Principles for why — this is the evidence instead.

v1.0.020 October 2026

First release, on Mac and Linux.
A Markdown editor with a live preview that renders maths, Mermaid diagrams and code highlighting as you type.
Every save is a commit. Browse the history of a file or the whole workspace and restore any version, free.
Wiki-links, backlinks, tags, daily notes and search across every note, all free.
Works on a plain folder of Markdown files, so your notes stay yours and sync however that folder does.
Tessamark Pro adds the knowledge graph, side-by-side diffs, an AI assistant with your own API key, Ghost publishing and PDF export. Monthly, yearly or a one-off purchase; one licence covers every platform.
