RegsUP is the regulatory platform from Anemon Innovation. This article introduces its related PDF product.

What should an update leave in the file?

UN R156 addresses approval in relation to vehicle software updates and the Software Update Management System (SUMS). The task extends beyond transferring a file to a vehicle: the relationship between a software change, the vehicle-type definition and the approval scope also needs attention.

Connect release notes to the vehicle configuration

Anemon recommends recording target vehicles, previous and new software identities, affected functions and verification records in the same release file. Show how the software team’s release name maps to the identification used in the approval documentation. Each team can then review the same change against a clear record.

Describe how the update is delivered

Explain workshop updates and remote distribution separately in the documentation. Target vehicle, installed hardware, changed function and post-update checks are the review headings we recommend. This article is not an update procedure or a conformity decision; it helps organise the project scope in which the relevant requirements will be applied.

How does this product differ from R155?

R156 covers software updates and SUMS. Cybersecurity and CSMS are addressed by the separate R155 publication. The offered file is the R156 01 series, with a store document version date of 4 June 2026. That date alone does not establish the legal application timetable. The product page does not state the date of the RegsUP explanations.

The regulatory edition date and guidance date are distinct. Product details alone do not establish acceptance for your project or inclusion of all subsequent amendments.

Sources and edition references

The official source supports the technical framework. Its text level, the store edition and the guidance date are distinct. Check the amendments and transition provisions applicable to your application separately.
