What is incident.io?

Alert rate limits stop being per-source and start being per-tenant, by query.

Investigations went generally available on 5 August, with Nexus posting a root-cause hypothesis and its evidence into the incident channel minutes after declaration. The releases since have been the operational surround: a 24/7 schedule coverage policy that flags gaps before a rotation goes unstaffed, more filtering in Insights, agent-written status page updates, and a resource-by-resource Terraform provider rework. This release lets an alert source extract a value from the incoming payload with a query expression and shard its rate limit on that value, so one noisy customer or cluster no longer consumes the whole source's budget.

What is Mergify?

Mergify's queue learned to merge stacked pull requests, then spent August tightening the edges.

Mergify automates merge queues for GitHub, and August was a mix of one real capability and a batch of contract cleanup. The queue can now merge GitHub-native stacked pull requests in order, speculative-check budgets apply per lane across dynamic scope sets, and conditions can match on whether a pull request came from a fork. Alongside that, the badge API was removed, pagination stopped advertising first and last links, and author-run commands were restricted to fork pull requests by default.

Alert rate limits stop being per-source and start being per-tenant, by query.

◆ Current state

Investigations went generally available on 5 August, with Nexus posting a root-cause hypothesis and its evidence into the incident channel minutes after declaration. The releases since have been the operational surround: a 24/7 schedule coverage policy that flags gaps before a rotation goes unstaffed, more filtering in Insights, agent-written status page updates, and a resource-by-resource Terraform provider rework. This release lets an alert source extract a value from the incoming payload with a query expression and shard its rate limit on that value, so one noisy customer or cluster no longer consumes the whole source's budget.

◆ Where it's heading

Two threads run in parallel. Nexus started inside the incident channel doing diagnosis and has moved outward to the customer-facing artifact. The second is platform work for customers running at scale — coverage policies, escalation routing, and now rate limiting that understands the shape of the payload rather than treating a source as one undifferentiated stream. Sharded limits are what you build when a single alert source fronts many tenants, which says something about the size of the deployments driving the roadmap.

◆ Prediction

Rate limits that read a query expression out of the payload share machinery with routing and deduplication, so the same expression surfacing in alert routing rules is the likely next step. The changelog entry does not say.

6.3

Mergify's queue learned to merge stacked pull requests, then spent August tightening the edges.

◆ Current state

Mergify automates merge queues for GitHub, and August was a mix of one real capability and a batch of contract cleanup. The queue can now merge GitHub-native stacked pull requests in order, speculative-check budgets apply per lane across dynamic scope sets, and conditions can match on whether a pull request came from a fork. Alongside that, the badge API was removed, pagination stopped advertising first and last links, and author-run commands were restricted to fork pull requests by default.

◆ Where it's heading

Two threads. The queue is absorbing workflows that used to sit outside it - stacked pull requests, flaky-test detection and rerunning within a CI budget - which pushes Mergify from a merge gate toward owning the whole pre-merge pipeline. The other thread is a deliberate narrowing of surface: deprecated endpoints removed, the github_actions action marked for removal in March 2027, default command permissions tightened around forks. That is a product trimming what it maintains so the queue can take on more.

◆ Prediction

Expect more of the pre-merge pipeline to move inside the queue on the flaky-test pattern, and further deprecations of automation that overlaps with what GitHub Actions now does natively.
