This release introduces file management, you can now tell Livebook what files the notebook depends on, be it on your disk or on the web. In relation to this, the images/ directory has been deprecated in favour of notebook attachments (files living in the files/ directory). One way to migrate is to rename the images/ directory to files/, open the files panel (in the session sidebar), then "Add file" and choose "From unlisted". If you want to automatically do this for a large repository of notebooks, you can try out this script.

This release introduces a breaking change to audio and image inputs. Previously input values (when read or received as an event) included a :data attribute with a binary. This attribute has been removed in favour of :file_ref, this way the binary is not stored in the memory upfront and it is up to the user to read it or stream it depending on the use case. For more information on the API, see Kino v0.11.0 changelog.
