@@ -24,9 +24,11 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Remove the "Success" interstitial after a proof of work challenge is concluded.
 - Anubis now has the concept of [storage backends](./admin/policies.mdx#storage-backends). These allow you to change how Anubis stores temporary data (in memory, on the disk, or in Valkey). If you run Anubis in an environment where you have a low amount of memory available for Anubis (eg: less than 64 megabytes), be sure to configure the [`bbolt`](./admin/policies.mdx#bbolt) storage backend.
 - The challenge issuance and validation process has been rewritten from scratch. Instead of generating challenge strings from request metadata (under the assumption that the values being compared against are stable), Anubis now generates random data for each challenge. This data is stored in the active [storage backend](./admin/policies.mdx#storage-backends) for up to 30 minutes. Fixes [#564](https://github.com/TecharoHQ/anubis/issues/564), [#746](https://github.com/TecharoHQ/anubis/issues/746), and other similar instances of this issue.
+- Make the [Open Graph](./admin/configuration/open-graph.mdx) subsystem and DNSBL subsystem use [storage backends](./admin/policies.mdx#storage-backends) instead of storing everything in memory by default.
 - Add option for forcing a specific language ([#742](https://github.com/TecharoHQ/anubis/pull/742))
 - Add translation for Turkish language ([#751](https://github.com/TecharoHQ/anubis/pull/751))
 - Allow [Common Crawl](https://commoncrawl.org/) by default so scrapers have less incentive to scrape
+- The [bbolt storage backend](./admin/policies.mdx#bbolt) now runs its cleanup every hour instead of every five minutes.
