+
+Hyperdrive pools database connections in one or more regions closest to your database. This means that your uncached queries and new connections have up to 50% less latency. In aggregate, we observed a decrease on average of \<ENTER NUMBER\>.
+
+With this update, Hyperdrive also uses [Cloudflare's standard IP address ranges](https://www.cloudflare.com/ips/) to connect to your database. This enables you to configure the firewall policies of your database to allow access to this limited IP address range.
+
+Refer to [documentation on how Hyperdrive makes connecting to regional databases from Cloudflare Workers fast](/hyperdrive/configuration/how-hyperdrive-works/).
+
+This improvement is enabled on all Hyperdrive configurations.
