+  request for both Prometheus and sidecar. Single requests now should take constant amount of memory on sidecar, so resource consumption prediction is now straightforward. This will be used if you have Prometheus `2.13` or `2.12-master`.
+- [#1358](https://github.com/thanos-io/thanos/pull/1358) Added `part_size` configuration option for HTTP multipart requests minimum part size for S3 storage type
