# July 2026

> API and SDK changes released in July 2026.

Additions, changes, deprecations, and breaking changes to the public Datagrid REST API and the `datagrid-ai` SDK, released in July 2026.

## Agents

**2026.07.13**

SDK · datagrid-ai\@0.16.1

* Changed`openai.gpt-5.5` is now an accepted `llm_model` value when creating or updating an agent, and when overriding the model on `POST /v1/converse`. ([reference](https://developers.datagrid.com/api-reference/agents/list-agents.md))

**2026.07.01**

SDK · datagrid-ai\@0.16.1

* ChangedThe default `agent_model` changed from `magpie-2.0` to `magpie-2.5` for agent create and update, and for `POST /v1/converse`. ([reference](https://developers.datagrid.com/api-reference/agents/list-agents.md))
  * *Migration:* Set `agent_model` explicitly to stay on `magpie-2.0`.

## Conversations

**2026.07.06**

SDK · datagrid-ai\@0.16.1

* BreakingMessage content can now be a structured JSON block. `MessageContentJson` was added to the message `content` union with a matching `json` discriminator value, on `POST /v1/converse` and both message-read endpoints. ([reference](https://developers.datagrid.com/api-reference/conversations/list-messages.md))
  * *Migration:* Clients that switch exhaustively on the message content type must handle `json`. Treat unrecognized content types as a non-fatal default rather than throwing.
