This short report brings to light some interesting commits to [scylla-cluster-tests.git master](https://github.com/scylladb/scylla-cluster-tests) from the last week. Commits in the 759e8884…0fb082b3 range are covered.

There were 27 non-merge commits from 11 authors in that period. Some notable commits:

The Docker backend [gained `simulated_racks` support](https://github.com/scylladb/scylla-cluster-tests/commit/a7a6e800fb265aa57042dd420ffedd8bc57f5824), lifting the single-rack limitation that broke `replication_factor>1` under `rf_rack_valid_keyspaces` enforcement.

A new plan to [normalize config option types](https://github.com/scylladb/scylla-cluster-tests/commit/2882837cd51ea4025c541b7f0bcced55cc733a32) was added, covering all 85 `StringOrList` /`IntOrList` /`BooleanOrList` /`DictOrStr` parameters so validators always return canonical types and `isinstance` guards can be removed across consumers.

AWS support was [extended with `eu-west-3`](https://github.com/scylladb/scylla-cluster-tests/commit/759e88849cbd731265452d39cd4d0905491cade3) and the supported-region list was consolidated into a single source of truth.

Latte was [bumped to 0.44.0-scylladb](https://github.com/scylladb/scylla-cluster-tests/commit/f8afb87c41e05155d3b6bd7ca44f5d50c39f24f9), notable for adding an Alternator (DynamoDB API) backend and updating the embedded `scylla-rust-driver` to 1.6.

Cassandra-stress was [updated to v3.20.6](https://github.com/scylladb/scylla-cluster-tests/commit/0dd23aea90f8ed0adc763c0a6075f0502d2c2db2), bringing driver update (v3.11.5.14 and v4.19.0.8).

Performance pipelines were [extended to accept a custom GCE Scylla image and Manager version](https://github.com/scylladb/scylla-cluster-tests/commit/ea549ee315f68c5d9aadba7269d8ad00b6f08aee) for backup-and-restore development work.

See you in the next issue of last week in scylla-cluster-tests.git master!
