Changelog

2.4.3 — 2026-08-26

Fixes a duplicate registration on sites that still have a physical App_Plugins folder for this plugin, left behind by an older release that copied content into the site. Umbraco registered those extensions twice - once from its own scan of the folder, once from this package's embedded manifest - and logged "Extension with alias ... is already registered". The embedded manifest now yields to the physical copy.

2.4.2 — 2026-08-24

Removes a dashboard screenshot that showed an error toast. It was captured against a site where this plugin's API was unreachable, so it advertised a broken dashboard. No screenshot is better than a misleading one; a replacement will be taken against a working install.

2.4.1 — 2026-08-24

Package metadata only: the listing now carries an icon and search tags, and the project and repository links point at the organisation that actually hosts this code. No code changes.

2.4.0 — 2026-08-23

The Razor view behind @await Component.InvokeAsync(...) is now compiled into the package. It was previously carried as a loose file that nothing packed, so the component threw "view not found" on every install and the front-end usage shown in this README could not have worked.

The view also still referenced the package's pre-rename namespace, so it would not have compiled even had it shipped. That is fixed, and the view is now built with the project — a broken view fails the build instead of failing a visitor's request.

2.3.0 — 2026-08-23

• A content editor can choose which event a page shows. The view component takes a numeric id, so until now putting an event on a page meant knowing that id and writing it into a template by hand — there was no way to pick one.

2.2.3 — 2026-08-22

• Registering for an event works. It returned 500 while saving the registration anyway: the response carried the attendee, which carried the event, which carried the attendees, and the serializer looped. From that point the event listing returned 500 too, for everyone — so one registration took the plugin down.
• Event listings no longer carry the people who registered. GetEvents and GetEvent are deliberately open so a front end can show what is on, and they were returning every attendee's name, e-mail and phone number to anyone who asked — the same disclosure that was closed on GetAttendees, reachable by another route. They now carry counts and spaces remaining; the attendee list stays behind GetAttendees, which requires backoffice access.
• A request body that cannot be read is answered with 400 and a reason, instead of a 500 from a null reference.

2.2.2 — 2026-08-21

• Dashboard now sends the backoffice token with its API calls. On Umbraco 17 those calls were arriving unauthenticated and coming back 401, which the dashboard rendered as an empty state rather than an error.
• A failed request now raises a notification instead of leaving the dashboard looking like there is simply no data.
• The plugin's tables are created on startup. They were never created before, so anything touching them failed on a fresh install.
• Runs on SQLite as well as SQL Server. It previously assumed SQL Server and failed with "Keyword not supported: 'cache'" on the database Umbraco's installer offers by default.
