Summer 2025 Update

21 May 2025

In May 2025, we published information on this page about advanced warning for key changes due for release in the Summer 2025 Update that may impact how your organisation uses HEAT, which are referred to as a breaking change.

To make members aware of these, we provided information regarding the changes two months in advance of deployment to the LIVE database in August 2025. For each item mentioned, we indicated areas that may be affected, depending on how your organisation uses the system. The Technical Road Map (members only) contains a full list of works, excluding bugs, completed as part of the Summer 2025 Update. This advanced warning outlined how key changes may impact your organisation’s:

  • Data (reporting objectives)
  • Imports and Export templates (which may be shared with other systems)
  • Reports
  • Changes to exports and reports can also affect data dashboards such as PowerBI. Any dashboards that HEAT provides will be adapted as part of the update
  • API processes
  • Internal processes (for example, how you use an element of the database to complete a task)

Is this a breaking change that affects the API?

No, this change will not affect the API.

Does this change affect the structure of Import and Export templates?

No, this change will not affect the Import and Export templates.

Does this change affect any data values on the database?

No, this change will not affect any data values on the database.

Is this a breaking change that affects the API?

This may potentially be a change that affects the API, please check your process if your organisation is using the following:

  • /Ambassadors endpoint
  • /Student endpoint
  • /Disabilities object
  • /Ethnicities object

Does this change affect the structure of Import and Export templates?

Yes, the addition of a new ‘Nationality’ field impacts the Student and Ambassador Import and Export template. If you use custom import templates, these will need to be updated to reflect the changes released. If you use Export templates in other software, this change needs to be considered.

Does this change affect any data values on the database?

Yes, the archival of values and the inclusion of additional values means that you should evaluate how you capture this information.

For example, the Ambassador and Student ‘Care Leaver’ field values of Unknown, Yes, and No are replaced by Looked after in Scotland (2), In care in the rest of the UK (3), Not a care leaver (5), Care leaver (6), Care experienced (7), Self-declared care experience but not confirmed (8), No experience of care (9), Not known (97), Prefer not to say (98), and Not available (99). The inclusion of multiple values means affected Unknown, Yes, and No field types have changed to a List.

As a consequence of these changes, any field that has been converted from Yes/No/Unknown to now include additional options will need Field Setting rules such as Required or Hidden reapplied. If your organisation has included additional text within the i-Button, this will need to be re-entered.

Please see our previous update for more information.
