# Versioning

## Version Format

Sensei IQ uses a date-based version number in the format:

```
YYYY.MM.DD.R
```

Where `YYYY.MM.DD` is the release date and `R` is the revision number for that date (typically `1`, incrementing if multiple releases go out on the same day).

For example: **`v2026.02.28.1`** — first release on February 28, 2026.

Sensei IQ is made up of three managed solutions — **Controls**, **Kaizen**, and **Atsumeru** — each of which carries its own version number. The version reported for your deployment is the highest version number across the three solutions.

## Release Cadence

Sensei IQ releases are issued on a roughly quarterly basis. There is no fixed schedule, and Sensei does not commit to shipping on a specific cadence — releases go out when they are ready.

There are two types of releases:

| Type | Description |
|------|-------------|
| **Major release** | The primary quarterly release, containing new features, improvements, and accumulated fixes. |
| **Hotfix** | An out-of-cycle release to address a critical issue. Clients are notified directly when a hotfix is available, and release notes are updated immediately. |

## Updates Are Always Optional

Sensei IQ updates are **never applied automatically**. Your environment is yours — Sensei will not push changes without your involvement. When a new release is available, your Sensei Engagement Lead will work with you to schedule and apply the update at a time that suits your organization.

Clients can choose to defer an update if the timing isn't right. Your Engagement Lead will advise if staying current is particularly important for a given release.

## Finding Your Version

The version numbers for all three solutions (Controls, Kaizen, and Atsumeru) are displayed in the upper right of the **What's New** page inside Sensei IQ. To arrange an update, contact your Sensei Engagement Lead.

## Release Notes

Full release notes for every version are available in two places:

- **In-app** — under **What's New** within the Sensei IQ application
- **Client documentation** — authenticated clients can view the full release history at [Releases](/client/releases/)

## Current Version

The current generally available release is **Q1 2026 — v2026.02.28.1**.
