Gave an agent a conversation history saved under a key.
What it does
Section titled “What it does”Workflows that already use Persistent Chat Memory keep working, with the same key and history. The node now runs as a Chat Memory with Storage: Key, your conversation key, and Key scope: Shared: old keys were shared by every workflow, and they stay that way. When you open the workflow, the node shows that it was upgraded; saving the workflow turns it into a Chat Memory node.
Conversations saved under a key used to be invisible in the app. They now appear on the Memory page under Workflows, marked Recovered.
When to use it
Section titled “When to use it”Don’t add it to new workflows. Use Chat Memory with Storage: Key, and prefer Key scope: This workflow unless several workflows really need to share the conversation.
Inputs and settings
