+
+In the latest [FerretDB](https://www.ferretdb.com/) v1.21 release, we added experimental support for the `SCRAM-SHA-1`/`SCRAM-SHA-256` authentication mechanisms.
+
+<!--truncate-->
+
+This release blog post will delve into how the new authentication mechanisms work and discuss our ongoing efforts to improve FerretDB.
+
+## Experimental support for `SCRAM-SHA-1`/`SCRAM-SHA-256`
+
+Earlier this year, we began work on enabling support for the `SCRAM-SHA-1` and `SCRAM-SHA-256` authentication mechanisms, which are now available for experimental purposes.
+Enable the new authentication mode by running FerretDB with the flag `--test-enable-new-auth`/`FERRETDB_TEST_ENABLE_NEW_AUTH` environment variable.
+
+Once a user is created using the `createUser` command, you can use the created user credentials in the connection string to connect to FerretDB.
+
+We encourage you to try the new authentication mechanisms and let us know your thoughts.
+
+## Bug fixes and enhancements
+
+In this release, we've reorganized `upsert` handling in `update` and `findAndModify` commands, fixing an issue where filter fields were incorrectly ignored and not appended when `upsert: true`.
+
+In addition to that, we improved the cleanup logic for capped collections in FerretDB to correctly handle document deletion when collections are configured with a size parameter without a `max` option.
+
+Check out our latest [release notes for the complete list](https://github.com/FerretDB/FerretDB/releases/tag/v1.21.0) of changes in this release.
+
+## FerretDB v2.0: it's coming!
+
+We released FerretDB 1.0 GA almost a year ago as the first open-source alternative to MongoDB, based on Postgres.
+Our aim with 1.x was twofold.
+First, we wanted to provide a production-ready alternative to encourage the open-source community to try FerretDB.
+Second, we wanted to get feedback on experience across a variety of different use cases and platforms.
+Today, with thousands of running FerretDB around the world, we are able to understand better what the expectations are.
+Your feedback, contributions, and telemetry data helped us to fine-tune our roadmap.
+
+While we continued working on FerretDB 1.x releases, in the background, we also turned our attention to addressing the elephant in the room: performance.
+
+The latest release is going to be one of the last releases of FerretDB v1.x.
+FerretDB v2.0 is just around the corner, with drastically improved performance and compatibility.
+FerretDB 2.0 will be a departure from our current architecture, which enables us to roll out these enhancements.
+
+We understand the need to make it easy for users to switch by offering a truly open-source alternative that is compatible with many of their existing needs.
+We believe FerretDB v2.0 should perform even better and enable even greater scalability and compatibility to support more application use cases.
+We hope to have it available for our users very soon.
+
+The open source community plays an integral role in everything we do at FerretDB, and we appreciate all the support from everyone, including partners, code contributors, and well-wishers.
+Particularly for this release, we are grateful to [@farit2000](https://github.com/farit2000), [@sbshah97](https://github.com/sbshah97) as first-time contributors to FerretDB.
