Summary
This page provides users with an overview of significant content updates in AMBOSS. At this time we are reporting newly published articles, sections that have undergone substantial rework of content, new multimedia/images, and new flowcharts on a monthly basis. Please note that not all changes are reported – smaller changes and updates are too numerous to also include here.
