# Incident Report 05/06/2025

**Start:** Xena/3.0.26 (May 20, 2025)

**End:** Planned for June 5, 2025 (flow changelog data retention fixed for existing records)

**Reach:** All changelog records created **before May 30, 2025** are unavailable for flows **created after the Xena release (May 20, 2025)** and **before June, 5**., unless their data retention settings were manually modified higher than this time range.

**Impact:** Medium – non-blocking

## Description

Following the release of version **`Xena/3.0.26`**, the changelog retention policy for flows on the Mindflow platform was unintentionally affected. Specifically, changelog entries for newly created flows were mistakenly included in a new TTL (Time To Live) logic, causing them to expire after 7 days. This behavior is incorrect. By design, flow changelogs must be retained indefinitely for auditing and traceability.

## Causes

The issue stemmed from a logic error in the flow creation process introduced in the `Xena` release. The issue inadvertently applied the flow retention policy (7 days) to changelog entries, deviating from the expected infinite retention.

This caused two issues:

- **New flows created after the `Xena` release:** changelogs were incorrectly configured to expire after 7 days.
- **Existing flows at the time of the `Xena` deployment:** changelogs were incorrectly configured to the global data retention policy (90 days by default), instead of being retained indefinitely.

---

## Resolution

A patch was deployed to:

- **Remove all expiration settings** from existing flow changelog entries, ensuring permanent retention.
- **Update the flow creation logic** to prevent any time-based expiration from being applied to new changelog entries.

With these changes, all changelog histories are now retained indefinitely, as originally intended.

:::note
However, changelog records created **before May 30, 2025** are permanently unavailable for flows **created after the Xena release (May 20, 2025)** and **before June, 5**.

## Follow-up

The Mindflow engineering team is conducting a platform-wide review of all data retention policies to ensure alignment with audit and compliance requirements. Priority is being placed on data critical to traceability, such as changelogs.
