This page currently tracks **documentation** changes we can verify directly, since we don’t yet have a confirmed, complete SDK release history to publish. If you need details on a specific past SDK release, ask in the [developer Telegram](https://t.me/terminal3developer) — we’ll backfill verified entries here as we confirm them.

## Documentation

### 2026-07-06

- Added [Quickstart](https://docs.terminal3.io/developers/adk/get-started/quickstart) — a single page to get an authenticated call working before touching contract code.
- Filled in the previously-empty [ADK Tour](https://docs.terminal3.io/developers/adk/overview/adk-tour) and [Agent Auth](https://docs.terminal3.io/developers/adk/overview/agent-auth-adk) pages.
- Added this [Changelog](https://docs.terminal3.io/developers/adk/changelog) and the [SDK & API Reference](https://docs.terminal3.io/developers/adk/reference) page.
- Fixed a duplicate “Step 4” between the Invoke and Test walkthrough pages.
- Expanded [Common Errors](https://docs.terminal3.io/developers/adk/tips/common-errors) with generic-HTTP-500 triage guidance and a table of common integration gotchas (tenant DID double-encoding, `baseUrl` handling).
- Added a warning about contract version-shadowing on re-registration to [Register your TEE contract](https://docs.terminal3.io/developers/adk/get-started/walkthrough/register-contract).

## SDK

Hackathon integrations have referenced `@terminal3/t3n-sdk` versions `3.5.2`, `3.9.0`, and `3.11.0` in the wild. We haven’t cross-checked these against an official release history yet, so we’re not listing per-version changes here until we can confirm them — a placeholder is worse than an honest gap.
