# Luna Streams v.0.6.2 documentation

## v.0.5.0

## Improvements:

> 1. [LUNA-5879] The DROI calculation mechanism was changed.

>    Previously, DROI represented coordinates relative to the ROI, taking into account the rotation of the image.

>    All existing streams will be updated according to the new DROI calculation mechanism.

> 2. [LUNA-5903] The live and last_frame stream preview were added.

>    See last frame preview and

>    last frame preview for details.

> 3. [LUNA-5911] The stream autorestart status was added. The stream autorestart mechanism was updated - the fatal error concept was added.

>    For more information see autorestart section of get stream response and

>    streams automatic restart.

> 4. [LUNA-5935] The include_luna_services parameter was added for healthcheck resource
