New features in June's product updates for Sentry include the release of the new Codecov CLI, which allows users to easily configure code coverage settings and identify gaps in their test coverage directly from their terminal. Additionally, a Crons Timeline View has been added, providing an intuitive overview of all Cron Monitors' status within a specific timeframe. Java developers can now link their source code to stack traces using Sentry's new Java Source context feature, which includes automated setup through Gradle and Maven plugins. Furthermore, SQL queries are now displayed with improved readability in the Sentry platform.
