AIOS Release Notes, June 2026: Day Zero to AIOS 3.0
The first two weeks: an idea written down on 17 June, and a system running in production on 2 July. Chapter one of the AIOS release history.
The starting point
The goal was a planning system that works the way people already work — writing things down — instead of one that has to be fed through forms. Everything in this first stretch served one question: can a daily note, written in plain language, be turned into a reliable plan without the person learning any syntax?
17–18 June — Day Zero
- First commit. A clean architecture from the start: data sources, a planner, storage for daily notes, and a command-line interface to drive it all.
- The daily note template. Every day gets a note with the same sections — focus, schedule, tasks, decisions, notes — so the system always knows where to look.
- The Daily Brief. A morning summary built from yesterday's note, today's note and the notebook as a whole.
- An adaptive planner that blends what you wrote with the momentum of what you have been working on, and explains its reasoning.
- Notes gained structured metadata (frontmatter), which every later feature depends on.
19–21 June — AIOS 2.2 to 2.6
- Stable, deterministic rendering. The same note always produces the same brief — the first appearance of a rule that still governs the product: parsers decide, not guesses.
- The first web dashboard. A dashboard shell with the Daily Brief, and backend endpoints for notes, system status, the roadmap and a vision board.
- A real notebook in the browser: live editing, autosave, manual save and a status bar.
23–28 June — AIOS 2.7 to 2.9
- The Continuity Engine. AIOS picks up where you left off: it finds the last note you actually worked in, carries unfinished items forward, and prepares today's note automatically when the day begins.
- A canonical "today" note. One reliable answer to "which note is today's", which the brief, the plan and the continuity engine all share.
- Working procedures for the project itself were written down as SOPs — the practice that later became a feature of the product.
1–2 July — AIOS 3.0, "Cognitive OS Active"
The milestone where AIOS stopped being a prototype.
- In production. A Python and Flask backend served by Gunicorn behind Apache on Linux, managed as a system service.
- A proper database. PostgreSQL, with the foundations for more than one user.
- Full notebook CRUD — create, read, update and delete — wired end to end through the dashboard.
- A weighted planner and scoring engine that ranks the day.
- The first AI integration, with the model chosen at run time from what the provider actually offers rather than a name typed into the code.
- Interaction logs: every conversation with the assistant is recorded in the notebook, so nothing said to it is lost.
