Breaking Changes

Issue #1

The default Agent Architecture has changed to `memgpt_v2_agent`. If you rely on the previous default architecture, you must explicitly configure the agent to use it.

Issue #2

Archival memory tools are no longer added by default to agents. If your workflow requires archival memory, you must now add these tools explicitly.

Migration Steps

  1. 1
    If you have long-running tools using streaming endpoints, you may need to add handling logic for the new `LettaPing` message type.
  2. 2
    If you were relying on the previous default agent architecture, update your configuration to explicitly use the desired architecture, as the default is now `memgpt_v2_agent`.
  3. 3
    If your agents previously relied on default archival memory tools, ensure you explicitly add them back if needed.

Release Summary

This release introduces the `LettaPing` message for stable long streaming connections and adds support for OAuth MCP providers. It also defaults agents to the new `memgpt_v2_agent` architecture and includes various performance improvements and bug fixes.
