Microsoft ships Fabric updates almost every week. In September 2026 a batch went Generally Available, and others sit in preview. If you run a data platform, the hard part is not reading the release notes. It is deciding which items improve your Microsoft Fabric monitoring and data quality, and which are noise. This post sorts the September updates into act now and watch, and flags one deprecation with a clock on it.
Which September updates change your Microsoft Fabric monitoring
The What's new page is long. Most entries will not touch your day. A few do. Read it the way you read an incident feed: what changed, does it affect my systems, do I act now or note it for later. Three items are worth your attention because they change what you can see, govern, or must migrate.
Here is the status of the September items that matter for a platform team. The status is the point, not a count, so the values below are capability states, not numbers.
- Generally Available (Sep 2026)
- Networking Communication Policies Admin API
- Preview
- Workspace monitoring
- Generally Available (Sep 2026)
- ODBC to ADBC driver transition
Sort them into three buckets. Turn on now: the networking view. Trial in preview: workspace monitoring and the OneLake catalog. Schedule a migration: the ODBC to ADBC move. The rest of this post takes each one in turn.
See every workspace's network posture in one call
The Fabric Networking Communication Policies Admin API is now Generally Available. It gives a tenant-wide, paginated view of your workspace networking policies. In one call you can list the inbound and outbound networking policies across every workspace in the tenant.
If you own many workspaces, you have probably lost track of which one allows what. Until now you checked them one at a time. A tenant-wide view means you can audit inbound and outbound policy in a script, catch drift when a workspace changes, and answer a security question in minutes instead of a morning. This is the one item to wire into your own checks first, because it is Generally Available and it needs no preview caveats.
