Feature: add new type Long JSON for custom user fields, allow to add up to 10 Long JSON user fields, also migrated AI Agent Messages to Long JSON type
New Custom User Field Type: Long JSON
A new custom user field type — Long JSON — is now available, designed to store large structured data objects per user. Up to 10 Long JSON fields can be created per workspace. Existing AI Agent Messages fields have also been migrated to the Long JSON type automatically.
What's New
- 🗂 New field type: Long JSON — stores large JSON objects as a custom user field value, beyond the size limits of the standard JSON field type
- 🔢 Up to 10 Long JSON fields per workspace — a dedicated allocation separate from other field type limits
- 🤖 AI Agent Messages migrated to Long JSON — the system field used to store AI Agent conversation history has been automatically migrated from the standard JSON type to Long JSON, enabling longer conversation histories to be stored reliably
- 📄 Accessible and editable via the standard User Fields interface alongside all other custom field types
How to Use
- Go to Settings → User Fields (or any interface where custom fields are managed)
- Click + Add Field
- Select Long JSON as the field type
- Name the field and save
- You can create up to 10 Long JSON fields per workspace

Why It Matters
- AI Agent Messages can now store much longer conversation histories per user without hitting JSON field size limits
- Partners and power users who store complex nested data (product configurations, form responses, CRM sync payloads) have a dedicated, larger field type to use
- The automatic migration of AI Agent Messages means no action is required — existing conversation histories are preserved and now more scalable
