TimescaleDB 2.9 is now available on Timescale Cloud and as an upgrade option for on-premise installations, offering new features such as hierarchical continuous aggregates, background jobs with fixed schedules and improved multi-node capabilities. These enhancements enable users to downsample their time-series data more efficiently, visualize complex datasets in real-time, and automate tasks with better scheduling options and runtime error visibility. The latest release also includes improvements to the `time_bucket_gapfill` function and introduces a new function to configure data node availability.
