What is Bugsnag?
Bugsnag adds trimmed-mean timings and disk I/O metrics to its mobile performance views.
October's release adds Trimmed Mean to Performance views, sitting beside percentiles so outliers don't hide or fake a regression, and Disk Usage (IOPS) to Resource Monitoring for Android and iOS, per span group. It follows September's iOS appHangCallback and GraphQL-by-operation network views, and August's source-side discard enforcement.
What is CircleCI?
CircleCI's SSH reruns now open from the browser, through one trusted address.
CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.
Bugsnag vs CircleCI: editorial side-by-side
Bugsnag
5.0INFRA · APIS
Bugsnag adds trimmed-mean timings and disk I/O metrics to its mobile performance views.
◆ Current state
October's release adds Trimmed Mean to Performance views, sitting beside percentiles so outliers don't hide or fake a regression, and Disk Usage (IOPS) to Resource Monitoring for Android and iOS, per span group. It follows September's iOS appHangCallback and GraphQL-by-operation network views, and August's source-side discard enforcement.
◆ Where it's heading
Bugsnag's monthly releases keep widening mobile performance coverage one metric at a time: CPU and memory in July, hangs and app-hang context through the summer, now disk I/O. The direction is a fuller resource picture per span, so a slowdown can be traced to its cause inside one tool.
◆ Prediction
The cadence suggests a November release with another resource or span-level metric, likely extending the per-span-group view rather than adding a new product area.
CircleCI
6.3INFRA · APIS
CircleCI's SSH reruns now open from the browser, through one trusted address.
◆ Current state
CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.
◆ Where it's heading
CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.
◆ Prediction
Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.
