Upgrade Guide

What a deployment gains by moving to a newer release, feature by feature, with each entry linking to its page in the Feature Catalog.

The list is generated from the catalog itself, so a feature appears under the release it actually arrived in rather than the release that last touched its code.

What changed between 7 and 8

Beyond the move from packages to containers, which is the part an operator feels first:

A new interface. 8.x is a rewrite of the front end rather than a reskin of 7.10.6 — a different shell, different navigation, and a layout that holds up on a phone.

Theming, and an appearance to go with it. Colors, logos and background images are configuration rather than a custom build, and users pick light, dark or follow-the-system for themselves.

Video conferencing. Zoom and Jitsi meetings attached to an appointment arrived in 8.0. 7.10.6 has no equivalent.

Accessibility conformance. 8.x publishes an Accessibility Conformance Report against WCAG 2.2 and EN 301 549, which is a procurement requirement in much of the public sector. 7.10.6 has none.

83 features. Not a round number because it is counted rather than claimed — see everything new since 7.10.6. Six of them are picked out under Highlights.

Breaking changes and requirementsThe other half of an upgrade: what a release asks of a deployment before or after the move

What these lists do not say

A feature shown as 7.x is absent from every range, because nothing is gained by upgrading to get it. That bucket is large: of 255 catalog features, 83 arrived during the 8.x line and the other 172 were already there.

Where a long-standing feature was reworked rather than introduced, the rework is noted on the feature's own catalog page instead of appearing here as if it were new.
