0.20.6-v1

Server deployment

Memory optimization

This release reduces peak server memory usage. Previously, memory grew with the total number of instances ever submitted; this is now fixed. We recommend upgrading if memory usage increases over time.

Logs storage

Fluent Bit + Elasticsearch/OpenSearch

Run logs can now be stored in your own log storage via Fluent Bit. At the same time, dstack can now read run logs from Elasticsearch/OpenSearch (to display in the UI and CLI), if Fluent Bit ships the logs there.

See the docs for more details.

Fleets

Since 0.20, dstack requires at least one fleet to be created before you can submit any runs. To make this easier, we’ve simplified default fleet creation during project setup in the UI:

In addition, if your project doesn’t have a fleet, the UI will prompt you to create one.
