Changelog

All notable changes to Agora will be documented here.

[7.20.1] - 2026-05-05

Added

  • HTML file viewer: uploading an .html or .htm file into a folder and clicking on it now renders the HTML in-browser using a sandboxed iframe. JavaScript is disabled in the viewer for security. SVG files and other assets referenced by relative paths are resolved through the Agora folder tree (e.g. if report.html references ./images/chart.svg, upload images/chart.svg into the corresponding subfolder and it will load correctly)

  • User-defined parameter sets on studies, series, datasets, patients, and folders: a new Parameters tab in the detail sidebar for each of these object types allows users to create and manage custom parameter sets attached to individual objects

  • Parameter Form Templates: project managers can now define structured data-entry forms in project settings (Project Settings → Form Templates). Templates appear in a new Forms tab in the detail panel for studies, series, datasets, patients, and folders. Two template types are supported: Field List (auto-rendered form with 13 supported field types) and HTML Layout (custom HTML with [[SetName.ParamName]] placeholders). Form values are stored as standard parameter sets and are searchable via AQL. See Parameter Form Templates.

  • Manually create patients: a new New Patient option in the Patient List dropdown lets users create a patient record directly, without first importing a study. Patients with no studies are flagged with a warning icon.

  • AEX automatic schema migration on import: .aex archives exported from older Agora versions are now automatically migrated to the current schema on import. Added, removed, and renamed fields and models are handled transparently without requiring manual intervention.

  • Push to / Pull from: two new project-level transfer operations synchronise an entire project against another — either on the same Agora instance or on a remote server. Push to… sends data from the current project to a selected target project; Pull from… brings data from a selected source project into the current project. Both operations are additive (nothing is deleted). A Transfer Preview shows the number of studies, series, datasets, and folders to be copied and the total data size before the transfer begins. Having both directions available is useful when a firewall only permits connections in one direction. See the Transferring Data Between Projects section in the Managing Data documentation.

  • Trigger: ParameterSet Created event: a new trigger event fires when a project member submits a Parameter Form Template for any object (exam, series, dataset, patient, or folder). System-generated parameter sets extracted automatically during import do not trigger this event. The trigger context contains the parent entity and its submitted parameter values.

  • Booking module: a new Booking section in the main navigation bar lets users reserve time on shared resources such as MRI scanners, lab equipment, or rooms. The week-view calendar displays one column per resource day with colour-coded booking chips. Recurring bookings (daily, weekdays, or weekly) can be created in a single step. Superusers can book on behalf of another user. Administrators can define resources (name, colour, time-step resolution, and availability window), optional booking groups for categorisation, and view usage statistics broken down by resource, group, and user via Settings → Booking.

Changed

  • Query interface improvements: inline help text is now available directly in the query editor

  • Query examples are now clickable and inserted into the query input directly

  • Queries can now return Folders and Patients as result types, in addition to the existing result types

  • Query execution performance has been slightly improved

  • Trigger filter and action scripts can now access user-defined parameter values on exams, series, patients, and folders via context['exam']['parameters'], context['series']['parameters'], context['patient']['parameters'], and context['folder']['parameters']. Previously only dataset-level parameters were available in the trigger context.

  • The Refresh Current View button now also reloads tags, rating instances, and parameter form templates for the current project. Previously these were only fetched on initial project open and required a full browser refresh to pick up changes (for example, a tag applied by a trigger).

  • Refactoring of the landing page

Fixed

  • NIfTI files are now displayed in the correct radiological convention in the viewer

[7.19.1] - 2026-04-10

Added

  • Triggers completely refactored and extended:

    • New events: Remove Study from Project, Remove Series from Project, Tag Added (with optional tag filter), and Manual

    • New actions: Rename (study, series, or folder), Move to Project, and Message (send a notification message; supports Jinja2 templating)

    • Trigger ordering: triggers watching the same event execute sequentially in the order shown in the list; drag rows to reorder. Later triggers see the results of earlier ones (e.g. a rename applied by the first trigger is visible to the second)

    • Project counters: per-project numeric counters that can be incremented by a trigger action and are available as variables in task scripts and folder path expressions

  • Display if update is available in the Information and License page

Fixed

  • Updating user settings no longer returns a validation error

  • Several dates were not respecting the date format set in the user’s profile settings

[7.18.3] - 2026-03-19

Added

  • Filter to the study list, patient list, project list, and folder view

  • Filter studies by tag in the study list

  • Project User Management: New roles and permissions have been added and the presentation is clearer and simpler
