Letta (MemGPT) 1.0 Stable Release

We are working to release a stable version of MemGPT in a 1.0 release, which will be intended for production use. The release will include:

• Refactoring of DB code (e.g. the MetadataStore) to solve scaleability and connection issues (e.g. #1488)
• Consistent API interface for the REST API and the Python SDK, such as matching parameters and return types
• Introduce stable database schemas and alembic migrations for future releases
• Addition of production-grade testing, logging, and access control

To view progress on the release, you can check the integration branch.

General Cleanup

• Remove all nonessential code, dead or retired code, unofficially supported code from the codebase
• Isolate non-core elements into package add-ons
• Refactor MemGPT configuration to separate out server (e.g. DB) configuration and LLM/embedding configuration

Logging

• Singular parent logger throughout codebase and removal of all print and printd calls (except for in the CLI)
• Consistent use of py logging best practices for libraries and applications

Data Schemas

• Consistent data schemas (e.g. AgentState) across CLI, Python Client, and REST API represented with pydantic models
• Manage all persisted state (e.g. agent state) in an ORM
• Supported DB migrations for all future versions using alembic

Auth + Access

• Removal of authentication and access control (determined to be out-of-scope: developers should implement this within their own applications)

Testing

• Automated testing for all officially supported integrations (LLM/embedding provider, storage provider) - remove any untested integrations (suggest migrating to adapters or fork)
• SLA Support:
  • Atomic unit and integration tests (should not depend on a live OpenAI API key for testing)
  • Static code analysis threshold prospector or components of)
• Full CI run for each patch within all supported minors for Python client (versions 3.10, 3.11, 3.12)

Documentation

• Add auto-documentation #1493

At present, I find that there is a problem with the generation of the open API. It cannot generate the correct parameters. Therefore, I can only manually modify the open API JSON file. The following is the /admin/users interface that I modified. It does not generate the body parameters for the GET request.

    "/admin/users": {
      "get": {
        "tags": [
          "admin"
        ],
        "summary": "Get All Users",
        "description": "Get a list of all users in the database",
        "operationId": "get_all_users_admin_users_get",
        "security": [
          {
            "HTTPBearer": []
          }
        ],
        "requestBody": {
          "description": "Parameters to filter users.",
          "required": true,
          "content": {
            "application/json": {
              "schema": {
                "$ref": "#/components/schemas/GetAllUsersRequest"
              }
            }
          }
        },
      "GetAllUsersRequest": {
        "type": "object",
        "properties": {
          "cursor": {
            "type": "string",
            "format": "uuid",
            "description": "Cursor to which to start the paginated request."
          },
          "limit": {
            "type": "integer",
            "description": "Maximum number of users to retrieve per page."
          }
        },
        "required": [],
        "example": {
          "cursor": "00000000-0000-0000-0000-000000000000",
          "limit": 50
        }
      },
