* Prevent `ARRAffinity` cookie loss on load-balanced targets by disabling `HttpClient` handler rotation. Long-running transfers and restores now stay routed to the same target instance.
* Add a cluster-wide Deploy worker lock to prevent concurrent deploys across load-balanced backoffice instances.
* Process Deploy disk triggers on a single load-balanced server instead of racing on every node.

### [17.1.0](https://github.com/umbraco/Umbraco.Deploy.Issues/issues?q=is%3Aissue+is%3Aclosed+label%3Arelease%2F17.1.0) (May 14th 2026)

### [18.0.0-rc2](https://github.com/umbraco/Umbraco.Deploy.Issues/issues?q=is%3Aissue+is%3Aclosed+label%3Arelease%2F18.0.0) (June 5th 2026)

Comment thread
ronaldbarendse marked this conversation as resolved.
* Migrate Nested Content (when `MaxItems = 1`) and single-block-mode Block List configurations to the new `Umbraco.SingleBlock` editor at import time.
* Major UI/UX overhaul of the Deploy experience in the backoffice. See [Backoffice UX refresh](#backoffice-ux-refresh) below for details.
* Improved support for running Deploy on load-balanced backoffice instances:
* Prevent `ARRAffinity` cookie loss on load-balanced targets by disabling `HttpClient` handler rotation, so long-running restores stay routed to the same target instance.
* Add a cluster-wide Deploy worker lock to prevent concurrent deploys across load-balanced backoffice instances.
* Process Deploy disk triggers on a single load-balanced server instead of racing on every node.

#### Backoffice UX refresh

Version 18 introduces a redesigned Deploy experience in the backoffice:

* A new sidebar workspace, launched from the environment name header app, replaces the transfer queue dashboard in the Content section. The workspace provides a single overview of the transfer queue, export queue, import, and restore environment operations.
* Redesigned transfer, queue, restore, compare, and export modals with consistent styling, improved error surfacing, and a cleaner status and operation layout.
* Refreshed status, schema, and configuration views in the management dashboard.
