Backward-compatible changes

Since July 1st 2021 the changes listed below are considered backward-compatible. Such changes will not be advertised or communicated before deployment. Consumers are expected to automatically handle and accept those changes gracefully and silently.

• New CSV files can be added to the ZIP export file to cover new uses-cases
• Existing columns can be deprecated. When this happens, their content will be replaced by a constant value that depends on the type of the field

Backward-incompatible changes

Since July 1st 2021, we are committed to advertise at least two months in advance to existing consumers backward-incompatible changes and to provide version control flags per consumer for at least two month before forcing the migration of existing exports to a new incompatible format.

The changes listed below are considered backward-incompatible:

• One or more CSV files are removed from the ZIP export file
• New columns are added to existing CSV data files
• Existing columns are removed from existing CSV data files

Update: Since December 27th 2023, adding new columns at the end of an existing CSV data files is not considered anymore as a backward-incompatible change.
