 - In an upcoming release, we will align multi-run and single-run workspace views, so when you drill into a single run, you'll see the same layout and configuration of panels as you've configured for the multi-run view, including any custom charts, layouts, and settings. The goal is help you stay in context and avoid re-work around configuring your views. However, this will remove the ability to customize unique single-run views, isolated from the rest of the workspace. Reach out to your W&B team or [support](mailto:support@wandb.ai) for any questions about the migration.
 - Over the next several releases, we will continue migrating existing team-level Model Registry to W&B Registry. For details and a reminder about the timeline, see the [W&B Registry GA announcement]({{< relref "#registry_ga_announcement" >}}) below.
 
-## Features
+## Known issues
+In v0.73.0, resizing or reordering workspace panels may not be reflected in saved views. This bug is fixed in v0.73.1. If you experience this issue, upgrade to v0.73.1, which includes the fix. If you can't upgrade, contact [support](mailto:support@wandb.ai) for a workaround.
 
+## Features
 - <a id="registry_ga_announcement"></a>We're migrating existing team-level Model Registry to W&B Registry in stages over the next several releases. **No action is needed on your end; W&B will automatically copy Model Registry assets for each team to a corresponding automatically-created team-level private registry.** Existing references to model collections in your old team-level Model Registry will still work.
     1. Server v0.73 (this release) includes an opt-out environment variable that will migrate the team's Model Registry automatically during the upgrade. Migration takes between 5 and 30 minutes for most organizations. During the migration, linking artifacts to either the old Model Registry or the new Registry will fail with an error. **Artifact logging and retrieval will not be affected**.
     2. In Server v0.74 (end of September), we will remove the opt-out flag and migration will happen during the upgrade.

 - When you toggle runs on or off, W&B no longer reloads the media for other runs in the panel.
 - Fixed a bug that could cause a report to crash when expanding or collapsing a section after pressing **Tab**.
 - Fixed a bug on mobile displays where scrolling could cause logged videos to automatically play in full screen.

+## Other changes
+- The custom grid layout was removed from W&B Workspaces with Server release v0.73.0. Previously, custom grid layout allowed you to adjust the size of individual panels within a section. Now, resizing a panel in a workspace section resizes all panels in that section, whether you configure the workspace using the [W&B App]({{< relref "/guides/models/app/features/panels/#manage-a-sections-panels" >}}) or the [Workspace API]({{< relref "ref/python/wandb_workspaces/workspaces.md#class-sectionlayoutsettings" >}}). Custom grid layout remains available in [W&B Reports]({{< relref "/guides/core/reports/_index.md" >}}) and the [Reports API]({{< relref "/ref/python/wandb_workspaces/reports.md" >}}).
