What shipped.

A plain record of what changed as Myo turns from a prototype into a companion you can live with.

• May 17, 2026v4.0.0-rc.2
  The design system moved into the product

  Myo now has one source of truth for palette, type, motion, mascot behavior, and boundary-page voice.

  • Added DESIGN.md as the source of truth for tokens, type, spacing, motion, and mascot behavior.
  • Made marketing and auth stay in the day palette, while app surfaces can still shift by local time.
  • Reworked onboarding, empty-thread prompts, tool activity, smart scroll, and boundary pages around Myo's calmer voice.
• May 15, 2026v4.0.0-rc.1
  The five pillars landed

  The v4 foundation arrived: adaptive environment, heartbeats, living chat, desktop companion, and readable skills.

  • Built adaptive environment scenes with time, weather, biome, and mode-aware visual tokens.
  • Scaffolded heartbeats, autonomous action, living chat artifacts, and the desktop companion.
  • Added markdown skills with parsing, scheduled runs, and a self-improving memory loop.
• May 15, 2026v4.0.0-strip
  The foundation got lighter

  The project shed old experiments so the v4 companion work could move faster.

  • Removed old gateway, Clawdbot, vibe-coding, docs, scraper, contacts, and workspace experiments.
  • Moved admin, templates, and feature marketing into legacy so they stay out of the build.
  • Removed roughly 140K lines and added the 14-table Convex schema for v4.
