# Stability and reliability polish (July 14, 2026)

> Post-launch reliability updates: stricter Attio select-attribute writability checks and a cooldown window on automated dependency updates.

A small post-launch pass focused on reliability and supply-chain safety.

## Bug fixes

**Stricter Attio attribute writability checks**
The [Attio CRM sync](/quickstart) now correctly gates writes on both archival state *and* attribute type when deciding whether a select attribute is writable. Upserts that previously slipped through against non-select attributes are now rejected cleanly.

## Updates

**Safer dependency updates**
Automated dependency PRs now honor a cooldown window before adopting freshly published package versions, reducing exposure to compromised or yanked releases in the supply chain.

**Cleaner telemetry test surface**
Internal telemetry test helpers now match the OpenTelemetry base class signatures they extend, keeping instrumentation exports stable across upgrades of the collector. No action required — see the [Dash0](/telemetry/dash0-setup) and [Grafana Cloud](/telemetry/grafana-setup) guides for setup.
