What is Bugsnag?

Bugsnag names GraphQL operations and lets iOS teams attach context to app hangs.

September's release is narrow and practical. The iOS SDK's new appHangCallback adds diagnostic context the moment a hang is detected, aimed at SwiftUI hangs where the stack trace alone doesn't show the cause, and GraphQL requests now appear by operation in Network performance views rather than under a single POST /graphql. It follows source-side discard enforcement in August and the Correlated Events work earlier in the year.

What is Mergify?

Mergify's merge queue now hunts the breaking PR by rerunning failed tests first

Mergify shipped more than a dozen changes in the last week of October. On the merge queue, failed batches now run the failing tests first in each split, stacked PRs enter the queue together, scope capacities work with Bazel, Pants and Turborepo scopes and patterns, and batch merge commits name the PRs they land. Test Engine gained Minitest, Jest and Mocha plugins and a setup path driven by a coding agent. Jinja2 expressions in configuration stopped being evaluated on October 31.

Bugsnag names GraphQL operations and lets iOS teams attach context to app hangs.

◆ Current state

September's release is narrow and practical. The iOS SDK's new appHangCallback adds diagnostic context the moment a hang is detected, aimed at SwiftUI hangs where the stack trace alone doesn't show the cause, and GraphQL requests now appear by operation in Network performance views rather than under a single POST /graphql. It follows source-side discard enforcement in August and the Correlated Events work earlier in the year.

◆ Where it's heading

Bugsnag is moving from single-service error tracking toward cross-service observability: Correlated Events, trace correlation, and the MCP server all point at workflows where an error in one service is causally linked to events in others. The Flutter SDK parity work (CPU, memory, rendering metrics) reflects a deliberate effort to close the feature gap between mobile and web monitoring. SDK Source-Side Discard Enforcement (remote rule push to SDK) reduces bandwidth and processing overhead at scale — a signal that larger enterprise deployments are a growth priority.

◆ Prediction

Correlated Events will likely expand to support more correlation dimensions — custom attributes, error clusters — and the MCP server toolset will grow to include mutation tools (creating alerts, snoozing errors) rather than just read-only access. The Performance Score metric will gain more visibility and dashboard integrations.

Mergify's merge queue now hunts the breaking PR by rerunning failed tests first

◆ Current state

Mergify shipped more than a dozen changes in the last week of October. On the merge queue, failed batches now run the failing tests first in each split, stacked PRs enter the queue together, scope capacities work with Bazel, Pants and Turborepo scopes and patterns, and batch merge commits name the PRs they land. Test Engine gained Minitest, Jest and Mocha plugins and a setup path driven by a coding agent. Jinja2 expressions in configuration stopped being evaluated on October 31.

◆ Where it's heading

Mergify is tying its merge queue to test data: Test Engine knows which tests fail, and the queue uses that to bisect faster with less CI. Monorepo build tools and stacked PRs are now first-class queue inputs.

◆ Prediction

More queue behavior driven by Test Engine results is likely, given that Fail First and the new test plugins shipped the same week.
