Sentry is highlighting 12 of its many partners, including Slack, with an ornament on their festive Sen-Tree each day leading up to Christmas. The integration between Sentry and Slack allows users to receive alerts about bugs or issues within their Sentry account, which can be customized to control the types of bugs notified and the Slack channel they appear in. This integration is designed for the "job side" of using Slack, allowing users to focus on work-related tasks while still enjoying some festive fun with GIFs and other holiday-themed content.
