Changelog — PHX Data Agent Starter

All notable changes to this product are documented here. This project follows Semantic Versioning. Breaking changes link to an upgrade note in docs/upgrading.md.

[2.1.0] — 2026-07-10

Added

• Signature animated hero: a rotating three.js “data constellation” (points wired to nearest neighbours with a query-pulse shader). three r165 is vendored (assets/vendor/three/, MIT) so fresh clones build offline; the scene ships as its own esbuild entry (js/hero.js) and is lazy-loaded by the HeroScene LiveView hook only where the hero canvas renders. Pauses off-screen/hidden-tab, honours prefers-reduced-motion, degrades to the CSS gradient without WebGL.
• New logo: query-path-in-hexagon mark with adaptive wordmark, plus an SVG favicon.

Changed

• Landing hero fully redesigned as a dark band with honest product copy — natural language to policy-enforced read-only SQL, the MCP endpoint, and local models via Ollama — beside a truthful terminal mock of the shipped horses demo dataset (generated SQL, policy check, grounded answer).
• Header and navigation restyled for the dark hero (mobile panel included).

[2.0.3] — 2026-07-10

Fixed

• Supported-version floor corrected again to Elixir >= 1.18 / OTP >= 27: hermes_mcp uses Elixir 1.18’s JSON module (CI on 1.17 proved 2.0.2’s floor still too low).

[2.0.2] — 2026-07-10

Fixed

• Supported-version floor raised to Elixir >= 1.17: the MCP stack’s peri dependency uses Duration (Elixir 1.17+) and cannot compile on 1.15/1.16. mix.exs, README, SECURITY.md, and the CI matrix now state the real floor.

[2.0.1] — 2026-07-10

Added

• LICENSE file carrying the PhxTemplates Commercial Licence (v2.0) summary with a pointer to the authoritative tier terms.
• README rewritten for the Data Agent Starter: model-free quickstart first, Ollama optional (matching the opt-in auto_pull behaviour), supported version floors aligned with SECURITY.md, and a customization guide. Added .env.example documenting the supported environment variables.

[2.0.0] — 2026-07-10

Fixed (final release hardening)

• External MCP clients can now call the natural_language_query tool: the handler previously crashed on the schema-validated (atom-keyed, question-only) params that standards-compliant clients send.
• The chat widget no longer collapses when a reply error arrives, so failures are actually visible.
• Removed the header’s dead “Log in” links (the starter has no auth) and pointed “Get Started” at the live demo section.

Security

• Removed all distributed credentials; secrets now load from the environment. Any key previously shipped in an archive must be treated as compromised and rotated (see the storefront security incident record).

Changed

• Standardised setup, .env.example, formatting, and the release gate against the shared PHX engineering baseline.
• Added AGENTS.md / CLAUDE.md agent-readiness guides.

Added

• SECURITY.md, SUPPORT.md, and this changelog.
