What it tracks

• Timeline — every release, categorized and searchable
• Milestones — curated turning points with narratives and supporting links
• Storylines — feature arcs (Agents, Safety, Models, MCP, Extensions) traced across releases
• Voices — X/Twitter posts from the team that supported key releases

Quick start

Open claude-code-timeline_8.html in a browser. No server, no build step, no dependencies.

Architecture

Single self-contained HTML file (~2500 lines) with embedded CSS and JS. Data constants drive everything:

Constant	Purpose
ERAS	Time periods dividing the timeline
MILESTONES	Key releases with titles, narratives, and links
VOICES	X/Twitter posts mapped to versions
STORYLINES	Narrative arcs with keyword filters and resources
THEMES	Category definitions, colors, and classification keywords
FULL_CL	Raw changelog (auto-updated)

Fonts: Inter, JetBrains Mono (Google Fonts CDN). Theming: Dark/light mode via CSS variables. Filtering: Category buttons + search with URL state persistence.

Automation

automation/update_timeline.py detects new Claude Code releases daily, condenses changelog entries, and injects them into the HTML file. Zero pip dependencies.

python3 automation/update_timeline.py              # Interactive
python3 automation/update_timeline.py --auto       # Unattended
python3 automation/update_timeline.py --dry-run    # Preview only
python3 automation/update_timeline.py --install-schedule  # Daily launchd job (9am)

Milestones, Voices, Storylines, and Eras are maintained manually.
