The unification of Cloud Composer 3 billing with BigQuery is paused until further notice

## Announcement The unification of Cloud Composer 3 billing with BigQuery is paused until further notice. The change was [previously scheduled for April 13, 2025](https://cloud.google.com/composer/docs/release-notes#January%5F12%5F2025). ## Issue In recently released Airflow builds of Cloud Composer 3, the Airflow web server requires more CPU to finish its initialization when an environment is created or updated. This might lead to longer operation times or failures to perform these operations. As a workaround, when you create a new Cloud Composer 3 environment or upgrade an existing environment, provide at least 1 CPU to the Airflow web server. This issue currently affects composer-3-airflow-2.10.2-build.12 and composer-3-airflow-2.9.3-build.19 Airflow builds.
