# Logbook - 2022-05-26

**Type:** Announcement

## Summary

The May 26, 2022 changelog records product, reliability, documentation, and web UI changes made while work continued toward the Fly Machines launch. Users can configure proxy protocol v2 headers, while Fly HA Postgres instances become read-only and fail health checks at 90% volume usage, creating time to respond before full disks cause crashes. The GraphQL API now names missing apps directly, API telemetry is more selective, and fixes address certificate and volume deletion errors, region-code mutation, DNS validation context, and delayed organization invitations. Documentation covers the Machines API, its reference and FaaS usage, fly.toml updates, and PlanetScale Portals, while redesigned dashboards, app and organization pages, paid plans, documents, and app-level views update the web interface.

## Context

Work toward the Fly Machines launch involved changes across the product, while other production lines continued to receive updates, including the web UI.

## Approach / What changed

The release adds proxy protocol v2 configuration, preemptive read-only behavior for Fly HA Postgres volumes at 90% full, clearer GraphQL errors, more selective API telemetry, fixes for several API and invitation edge cases, new documentation, and redesigned web UI areas.

## Takeaways

- Fly HA Postgres instances turn read-only and fail a health check when their volume reaches 90% full, giving users an opportunity to react before a full disk causes a crash.
- The GraphQL API reports “Could not find ” when an app cannot be found, replacing the less specific “Could not resolve App” message.
- The web UI gained redesigned Apps, app, organization, and paid plans pages, plus a documents UI, region information for volumes, and a Machines tab for apps.
