# Change Logs

Change logs for the Concurrence API, Agent Forge, Web Platform, and SDK ecosystem.

Use these logs to understand a change and the migration work it may require. Use the current [API Reference](/api-reference/readme.md) and [Developer Guide](https://docs.concurrence.com/developer-guide) for today's implementation contract.

Numbered package entries describe a published version. Unnumbered API or web entries describe source changes without claiming a release version or deployment date. Older entries may describe routes, fields, or workflows that have since been retired; their wording is historical.

## September 19, 2026: Concurrence Documentation Rebrand

Amigo is now **Concurrence**. Documentation names, navigation labels, brand artwork, repository links, and cross-space links use the new identity and `docs.concurrence.com`. Existing page paths and heading anchors are retained.

This is a documentation-only release, not an API or SDK version. API endpoints, credentials, package names, imports, environment variables, and wire identifiers are not renamed by this change. Historical entries retain the product names used at the time. See [Rebrand and Compatibility](https://docs.concurrence.com/reference/concurrence-rebrand).

The [September 14 Platform conversation-context entry](/api-reference/change-logs/amigo-api.md#conversation-context-and-tool-bindings) covers service schemas, per-state tool bindings, and current runtime limits.

## Maintaining an Integration

Start with [Current Upgrade Guidance](/api-reference/change-logs/upgrade-guide.md) to identify your API and package, check current boundaries, and choose compatibility tests. The API and web history pages retain recent entries and link to bounded archives; old entry headings continue to forward to the full historical text.

## Current SDK Packages

Package registry snapshot checked on **September 8, 2026 (UTC)**. Recheck the linked registries when selecting an upgrade.

| SDK                     | Package                                                                                            | Version to inspect |
| ----------------------- | -------------------------------------------------------------------------------------------------- | ------------------ |
| Platform TypeScript SDK | [`@amigo-ai/platform-sdk`](https://www.npmjs.com/package/@amigo-ai/platform-sdk)                   | `0.108.1`          |
| Classic TypeScript SDK  | [`@amigo-ai/sdk`](https://www.npmjs.com/package/@amigo-ai/sdk)                                     | `2.1.0`            |
| Classic Python SDK      | [`amigo-sdk`](https://pypi.org/project/amigo-sdk/)                                                 | `2.0.1`            |
| Scribe TypeScript SDK   | [`@amigo-ai/scribe-typescript-sdk`](https://www.npmjs.com/package/@amigo-ai/scribe-typescript-sdk) | `0.14.0`           |

{% hint style="warning" %}
The npm `latest` tag for `@amigo-ai/sdk` now points to `2.1.0`. The accidental `1.1.x` versions remain deprecated. Review the [September compatibility changes](/api-reference/change-logs/sdk-ecosystem.md#september-2026-compatibility-releases), pin the version you have tested, and keep Classic packages separate from `@amigo-ai/platform-sdk`.
{% endhint %}

Platform `0.108.1` is published on npm. It retains the retired-helper and voice-only fleet-status changes introduced in 0.108.0; review those changes before upgrading from older versions.

The experimental [Forge MCP tool](https://github.com/concurrence-hq/forge-mcp) is published separately as [`@amigo-ai/forge-tools` 0.1.14](https://www.npmjs.com/package/@amigo-ai/forge-tools). It uses Classic organization credentials and is not the Platform SDK or the Agent Forge CLI. See the [September package maintenance notes](/api-reference/change-logs/sdk-ecosystem.md#september-2026-package-maintenance).

## Versioning Policy

Published packages should follow [Semantic Versioning](https://semver.org/) where package versions are available. API and web changelog entries should not claim a dated release unless public release metadata confirms it.

Latest numbered API version: v0.9.557

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.concurrence.com/api-reference/change-logs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
