We have released an updated version of Snowplow’s BigQuery loader
We made this release to upgrade the base docker images due to a system library that had a known potential security vulnerability.
If you are already using a recent version of the loader, then upgrading is as simple pulling the most recent docker images
docker pull snowplow/snowplow-bigquery-streamloader:1.5.2 docker pull snowplow/snowplow-bigquery-mutator:1.5.2 docker pull snowplow/snowplow-bigquery-repeater:1.5.2
The Snowplow docs site has a full guide to running and configuring the loader.
