Service API version 5.0 contains breaking changes compared to the previous version, 4.x. These breaking changes require code changes in website implementations that depend on the Service API.

- Unlike previous versions that use direct access to `MetaObjects`, ServiceAPI 5.0 uses content API to read and update the properties of entries/categories. So, if a property has special parsing or processing for get or set actions, the data might be changed compared to previous versions. To avoid such changes, update your data model's `MetaFieldData` to the data you want the property to have.
- `model.IsActive` determines the status of the content version. `IsActive = true` publishes the content. Otherwise, content is left in draft state.
  Previously, there was a workaround to add a `MetaField` named `Epi_IsPublished` to control the publish state of the content. This workaround is inoperable in ServiceAPI 5.0.
- Updating catalog contents via ServiceAPI fires off content events, which can be listened to via IContentEvents.
