Highlights

• ✍️ Messages are edited as formatted text: Writing a message meant editing Markdown source and checking a separate preview. The message and reply editor now shows formatting, links and course references directly while typing. See #14254.

• 📬 Conversations open at the first unread message: Conversations open where the reader left off, while fully read conversations open at the newest message. Thread replies now also count as unread for their recipients. See #14288.

• 📋 Scores and participations share one page: Instructors and tutors switched between two pages to manage participations, check results and export. Both now live on Participations, one row per participation with its latest result; old Scores links redirect there. See #14212.

• 🏗️ Build controls for instructors: The participation submissions page shows queued and running builds and refreshes results when a build finishes. "Trigger All" now waits for room in the build queue instead of queueing every build at once, so student pushes are not held back. See #14290 and #14291.

• 🎥 Courses can be connected to TUM.Live: Instructors can connect an Artemis course to a TUM.Live course from Course Management → TUM.Live, approving the connection in TUM.Live. This first step covers connecting and disconnecting, not video upload. See #13693.

• 🧪 Artemis can start with a complete demo course: The opt-in demo profile seeds a course with users in every role, exercises of every type in different states, a test exam, lectures, competencies, tutorial groups and messages. See #13416 and #14109.

Development

Important information for administrators

• ⚠️ Switch off the Memiris feature toggle before deploying the new Pyris: Artemis no longer integrates Memiris. Before a Pyris version without Memiris is deployed, the Memiris toggle must be off on every Artemis using it; the database columns stay for now, so a rollback still works. See #14315.

• 🔑 SAML2 starts again with all identity provider metadata: A newer commons-codec made SAML2 fail at startup with Unable to base64 decode data for valid certificates with other line layouts, reported after an upgrade to 10.3.1. Artemis now pins commons-codec to 1.22.1; no configuration change is needed. See #14312.

• 🎥 The TUM.Live connection is off by default: To offer it, register Artemis as an application in TUM.Live and set artemis.tum-live.integration-enabled, api-base-url, web-base-url and api-key. Without them, nothing changes. See #13693.

• 🏗️ Bulk builds wait for queue room: The new artemis.continuous-integration.bulk-trigger.max-queued-jobs-per-build-slot (default 2, 0 disables the wait) and max-wait-minutes (default 180) limit how many bulk builds are queued at once. See #14291.

• 🧪 Never enable the demo profile on a production server: The demo profile creates demo accounts with the publicly documented password demo1234. See #14109.
