About Fabric GPS

Fixes since v4.5.1

• Disabled unintended MCP subscription streaming. Modern subscriptions/listen now receives the SDK's completed JSON HTTP 404 METHOD_NOT_FOUND error instead of holding an SSE stream open.
• Corrected MCP lifecycle telemetry so HTTP 200 headers alone cannot count as successful completion. Fixed response-format, completion, disconnect and cleanup dimensions distinguish incomplete responses from completed responses with long cleanup.
• Added separate response and cleanup timings while retaining total handler duration. Normal read-only tools, configuration, security controls and SQL concurrency safeguards are unchanged. Telemetry continues to exclude sensitive payloads and client metadata.
• Updated MCP documentation with lifecycle precedence and safe diagnostic KQL.

Verification and limits

Offline validation: 76 focused MCP tests; full suite 922 passed, 5 native SQL tests skipped. Real SDK regression reproduces the old stream behavior and verifies rejection, protocol capabilities and normal client use with mocked reads.

The historical approximately 1,800-second termination source remains unknown. Completed ASGI sends do not prove remote delivery. This release does not certify production deployment, Front Door behavior or Azure ingestion, and does not include workbook or CLI-example changes.

This release adds privacy-safe MCP observability through the existing Azure Monitor and OpenTelemetry integration.

Improvements

• Request monitoring: Track MCP initialization, discovery, notifications, and tool requests, including duration, response status, and outcome.

• Tool usage insights: Track tool attempts, execution, latency, and failures—including tool errors returned with HTTP 200.

• Failure visibility: Capture validation failures, Host/Origin rejections, throttling, concurrency limits, timeouts, and cancellations.

• Correlated diagnostics: Connect MCP request and tool observations through OpenTelemetry traces.

• Updated documentation: Includes Application Insights queries for investigating usage and performance.

Privacy

MCP telemetry excludes request bodies, search text, tool arguments and results, user identifiers, credentials, and raw exception details. Usage counts remain subject to telemetry sampling and retention; they are not unique-user or billing measurements.

Deployment

Uses the existing Application Insights configuration—no new environment variables or dependencies are required. Export remains disabled in development or when no Application Insights connection string is configured.

Fabric GPS now helps you explore roadmap trends, return to the changes you haven’t seen, and bring Fabric roadmap context into your own tools.

What’s new

Roadmap Insights

Explore roadmap activity by product, status movements, release-window changes, and planned releases per quarter. Follow chart links into the underlying changes, with detailed evidence available when you need it.

Shareable saved views

Save your preferred filters in your browser and share a view through a link. Reopen, rename, or remove saved views without creating an account.

Changes since your last visit

Newly observed roadmap changes are highlighted automatically when you return. Your first successful visit establishes a baseline; subsequent visits track unseen changes within the retained 90-day history. Visit state stays in your browser—there’s no manual “mark as seen” step.

Read-only MCP endpoint

Connect compatible AI assistants to search Fabric roadmap releases, look up individual features, read release history, and discover available filters through the public /mcp endpoint.

Release notes on About

See published Fabric GPS release highlights at the bottom of the About page.

A clearer, more usable interface

• A compact, task-first homepage puts filters and roadmap results ahead of promotional content.

• Mobile filters use a More filters disclosure with named active criteria.

• Insights panels size independently, with larger chart links and accessible supporting detail.

• Navigation clearly identifies the current section.

• About has shorter, more readable product and source information.

• The API page now starts with RSS, REST, and MCP connection examples, with copyable commands and organized reference sections.

• Failed homepage requests offer Retry without losing your current view or already loaded results.

Accuracy and reliability

• Daily changelog pages preserve repeated edits and removals.

• Case-only content changes are included in change detection.

• Roadmap descriptions handle flattened formatting more cleanly.

• Saved views, filtering, browser navigation, and request handling work consistently together.

Deployment notes

• Deployments must apply the new blog-feedback database migration; normal startup runs Alembic migrations.

• Web hosting now includes MCP through the bundled ASGI/Gunicorn configuration. Custom launch commands should be checked against the updated deployment documentation.

• Reverse proxies and CDNs must bypass caching for MCP and respect private/no-store changelog responses.

• About-page release notes are captured during the image build, so this release appears there after the corresponding image is built and deployed.
