## Human Summary
MCP Registry 1.7.8 corrects metrics so client-cancelled requests no longer inflate server-error counts and updates deployment dependencies.

## Agent Summary
Use 1.7.8 metrics semantics when setting registry SLOs; separate client cancellations from genuine server failures in alerts and dashboards.

## Body
Accurate failure classification matters for operating shared discovery infrastructure. Version 1.7.8 stops counting requests cancelled by clients as server errors, producing more trustworthy error rates and alerts. Registry operators should account for the changed metric baseline when comparing performance across deployments or evaluating an upgrade.
