# Changelog

Source: https://swapcard.dev/analytics-api/changelog


The Analytics changelog is a list of recent and upcoming changes to our Analytics API. It includes backwards-compatible changes, schema previews, and upcoming breaking changes.

Every entry is labelled so you can scan for what affects you. **Breaking** changes can break existing queries or change runtime behaviour; **Deprecated** items keep working until the removal date announced in the entry, following the [versioning and deprecation policy](/deprecation-policy).

## `time_gt` is now required
_2024-08-22 · Breaking_

Effective today the `time_gt` parameters is mandatory on the analytics endpoint.

In a few weeks, the `time_lt` parameter will also be enforced and become mandatory, as announced in December 2023. By proceeding this way, we believe sufficient time has been provided for the systems to be updated in line with the changes announced earlier in the year.

## Time range parameters become required
_2023-12-01 · Breaking_

Effective December 1st 2023, the `time_gt` and `time_lt` parameters will be mandatory on the analytics endpoint.
