# Pre-announcement for FollowTheMoney 4.0

We're working on a new major release of [FollowTheMoney](https://followthemoney.tech/), the data model [underlying OpenSanctions](/reference). This major release cleans up some aspects of the domain model. The changes mostly affect schemata not used by OpenSanctions. However, we want to list the relevant upcoming changes here:

* The `CryptoWallet:mangingExchange` property will be renamed to `CryptoWallet:managingExchange`. This property is used by the `il_mod_crypto` dataset. Please **update any client/import code reliant on this property** to use the new name.
* The `Sanction:duration` property will change its datatype from `string` to `number`. The property values remain strings in the JSON export format, and may still contain a unit specification (eg. `2 years`). It is very likely that no action needs to be taken by data consumers.

Non-relevant schema changes:

* The `Post` and `Assessment` schemata will be deleted. Both are unused by OpenSanctions.
* Several other properties - not used in OS - will change: `License:area` (`string` to `number`), and the `UserAccount:number` property will be renamed to `UserAccount:phone`. The `Company:ibcRuc` property is to be deleted.

We will provide a more detailed change log when the release is published. This announcement merely serves as an early advisory regarding schema changes.
