+# 9.10.0

+* Simplify the logic for deciding whether to initialize `GovukPrometheusExporter`. `GovukPrometheusExporter` provides the `/metrics` webserver and "exporter" process for aggregating counters in multi-process apps. govuk_app_config will now always attempt to initialize GovukPrometheusExporter except when running under `rails console`. The `GOVUK_PROMETHEUS_EXPORTER` environment variable no longer has any effect.

 # 9.9.2
 
 * Add single cookie consent api URLs ([#355](https://github.com/alphagov/govuk_app_config/pull/355))
