Upgrade notes

Kubernetes version for Azure deployments: 1.20.9

Improvements have been made to previewer services to reduce the number of cascading failures that could occur if a previewer failed.
The report status now automatically refreshes when a report is being generated.
The audit log now contains a filter that allows you to filter on the user.

On-premises deployments were failing during the installation if the installer did not have access to the internet.
Pictures with the MIME type x-ms-bmp weren't having previews rendered.

An issue with the Filmstrip previewer service is causing them to exceed their memory limits, which cause the pods to be terminated. Workaround: Configure the maximum number of video requests to be 2 or less and the Filmstrip previewer pod should not get into a state where it runs out of memory.
In evidence uploaded from Cellebrite Physical Analyzer, duplicate artifact fragments can be generated if an XML element from the Cellebrite export contains a nested element of the same type.
Keyword searches applied by the user don't get highlighted in PDF previews if the content exists in the table of contents, links, or occurs over multiple lines.
When the user previews a picture or PDF attachment in the artifact hit details view, the audit log incorrectly records the action as a download event. PDF documents can trigger multiple download requests on hit details page open.
When the same user applies tags in quick succession, it can cause subsequent tag requests to throw an error.
Bulk actions for applying tags or comments do not immediately update the tag color stripe or update the comment counter in the UI. A webpage refresh can sometimes be required for this to take effect.
Switching to fullscreen in a document preview sometimes causes some UI elements to resize off the screen. This occurs most frequently with larger documents.
