Read this post for important information on migrating to alternatives. - Author: Daniel Chalef - Tags: #scarlett Now that we've moved to Zep's new graph memory, we'll be retiring several Zep features on **May 31, 2025**. ## What’s Changing Below is a quick overview of the features being retired, along with their recommended alternatives to help you transition smoothly: Python TypeScript | Function | SDK Method | Recommended Alternative | | ------------------------- | ---------------------------- | --------------------------------------------------------------------------------------------------------------- | | Search memory | memory.searchSessions | [graph.search](https://help.getzep.com/api-reference/graph/search?ref=blog.getzep.com) | | Search sessions for query | memory.searchSessions | [graph.search](https://help.getzep.com/api-reference/graph/search?ref=blog.getzep.com) | | Update a session | memory.updateSession | | | End a session | memory.endSession | | | End sessions | memory.endSessions | | | Session summaries | memory.getSummaries | [memory.get.context](https://help.getzep.com/api-reference/memory/get?ref=blog.getzep.com) | | Update message metadata | memory.updateMessageMetadata | | | Synthesize a question | memory.synthesizeQuestion | | | Retrieve fact by UUID | memory.getFact | [graph.edge.fact](https://help.getzep.com/api-reference/graph/edge/get?ref=blog.getzep.com) | | Delete fact by UUID | memory.deleteFact | [graph.edge.delete](https://help.getzep.com/api-reference/graph/edge/delete?ref=blog.getzep.com) | | Return facts for session | memory.getSessionFacts | [memory.get.relevantFacts](https://help.getzep.com/api-reference/memory/get") | | Add facts to a session | memory.addSessionFacts | [graph.addFactTriple](https://help.getzep.com/api-reference/graph/add-fact-triple?ref=blog.getzep.com) | | Retrieve user facts | user.getFacts | [graph.edge.getByUserId](https://help.getzep.com/api-reference/graph/edge/get-by-user-id?ref=blog.getzep.com) | | Retrieve group facts | group.getFacts | [graph.edge.getByGroupId](https://help.getzep.com/api-reference/graph/edge/get-by-group-id?ref=blog.getzep.com) | | Document Collections | all | | | Function | SDK Method | Recommended Alternative | | ------------------------- | -------------------------------- | --------------------------------------------------------------------------------------------------------------------- | | Search memory | memory.search | [graph.search](https://help.getzep.com/api-reference/graph/search?ref=blog.getzep.com) | | Search sessions for query | memory.search\_sessions | [graph.search](https://help.getzep.com/api-reference/graph/search?ref=blog.getzep.com) | | Update a session | memory.update\_session | | | End a session | memory.end\_session | | | End sessions | memory.end\_sessions | | | Session summaries | memory.get\_summaries | [memory.get.context](https://help.getzep.com/api-reference/memory/get?ref=blog.getzep.com) | | Update message metadata | memory.update\_message\_metadata | | | Synthesize a question | memory.synthesize\_question | | | Retrieve fact by UUID | memory.get\_fact | [graph.edge.fact](https://help.getzep.com/api-reference/graph/edge/get?ref=blog.getzep.com) | | Delete fact by UUID | memory.delete\_fact | [graph.edge.delete](https://help.getzep.com/api-reference/graph/edge/delete?ref=blog.getzep.com) | | Return facts for session | memory.get\_session\_facts | [memory.get.relevant\_facts](https://help.getzep.com/api-reference/memory/get?ref=blog.getzep.com) | | Add facts to a session | memory.add\_session\_facts | [graph.add\_fact\_triple](https://help.getzep.com/api-reference/graph/add-fact-triple?ref=blog.getzep.com) | | Retrieve user facts | user.get\_facts | [graph.edge.get\_by\_user\_id](https://help.getzep.com/api-reference/graph/edge/get-by-user-id?ref=blog.getzep.com) | | Retrieve group facts | group.get\_facts | [graph.edge.get\_by\_group\_id](https://help.getzep.com/api-reference/graph/edge/get-by-group-id?ref=blog.getzep.com) | | Document Collections | all | | With the retirement of `memory.search` and `memory.session_search`, searching for chat messages will no longer be supported. We recommend using node summaries instead, as they provide a richer and more accurate context for agents. ### Facts and Fact Ratings Changes We're removing several session-level memory attributes. The `fact_rating_instruction`, `facts`, and `fact_instruction` attributes will no longer be supported when creating *sessions*. *Fact Ratings* may now be applied when creating *Users* and *Groups*. ### Timestamp values The `updated_at` attribute is being removed from input values—developers should use `created_at` for ordering instead. ### Session Summaries and Summary Instructions Session Summaries are now deprecated, and so too is the ability to set a `summary_instruction`. Please [search for node summaries](https://help.getzep.com/searching-the-graph?ref=blog.getzep.com) as an alternative. ### Session Search and `min_score` Users now have a user-level graph and facts instead of session-level facts. As a result, `search_sessions` and `search` are deprecated. Zep's graph search now runs through a multi-stage pipeline with preset minimum scores at each stage, making the `min_score` attribute obsolete. ### Metadata Metadata for User, Session, and Message entities is now deprecated and will soon be replaced with new functionality. We'll share more details on this in late Q1 2025. ### Document Collections With the availability of many high-quality RAG services, we're deprecating Zep's Document Collections functionality. If needed, you can [add document chunks](https://help.getzep.com/adding-data-to-the-graph?ref=blog.getzep.com) to User or Group graphs using `graph.add` with `type = text`. ## How to Migrate 1. **Upgrade to SDK v2.5+** – Ensure you’re using the latest Python or TypeScript SDK. 2. **Update Your Code** – Replace deprecated features with the alternatives listed above. 3. **Test Before May 31, 2025** – Verify that your integration works smoothly before the cutoff. ## Need Help? - [**Updated Documentation**](https://help.getzep.com/concepts?ref=blog.getzep.com) – Check the latest SDK examples. - [**API Guide**](https://help.getzep.com/api-reference/memory/add-session?ref=blog.getzep.com) – Additional details. - [**Join Our Discord**](https://discord.gg/2JbGZQZT?ref=blog.getzep.com) – Connect with our team and developer community.
