<details><summary>1.19.0</summary>
## [1.19.0](https://github.com/grafana/alloy/compare/v1.18.0...v1.19.0)
(2026-08-21)
### ⚠ BREAKING CHANGES
* **prometheus.operator.servicemonitors:**
`prometheus.operator.servicemonitors` now rejects ServiceMonitor
endpoints that reference local files through `bearerTokenFile`,
`tlsConfig.caFile`, `tlsConfig.certFile`, or `tlsConfig.keyFile` by
default. Set `allow_arbitrary_file_access = true` to preserve the
previous behavior for trusted ServiceMonitor authors.
* The memory_limiter processor's internal telemetry metrics were renamed
upstream in OpenTelemetry Collector v0.155.0 to carry a memory_limiter
prefix
* Remove the prometheus.write.queue component
([#6814](https://github.com/grafana/alloy/issues/6814))
