Updated Markdown parser

December 13, 2021 - January 6, 2022: Version 3.61

The Markdown parser used in Databricks notebooks has been updated. The new version is faster when rendering. Some behavior has changed. The new behavior is closer to the commonmark spec.

The primary changes are:

  • You must now put a space between the hashtags and the text of a heading.

  • When you mix HTML and Markdown code in a cell, you must put a newline after each HTML start tag.

For example, the Markdown code to produce this result:

correct rendering

is as shown:


## Heading

New workspaces do not rely upon Google Cloud Deployment Manager

December 14, 2021

New workspaces do not use Google Cloud Deployment Manager to deploy network and storage cloud resources. There are two consequences of this change:

This change does not affect existing workspaces. The custom role created for existing workspaces continues to include the ten deploymentmanager. permissions. If the workspace is deleted, the workspace deployment and cloud resources are deleted.

The breaking change to environment variable behavior that was introduced in some workspaces last month will be reverted on December 3, 2021 from 01:00-03:00 UTC.

Accelerate workloads with Photon (Public Preview)

December 2, 2021

Photon is the new native vectorized engine on Databricks, directly compatible with Apache Spark APIs. It is included as part of a new high-performance runtime designed to run your workloads faster and reduce your total cost per workload. This runtime is a variant of the standard Databricks Runtime for version 9.1 and above. Photon is selectable when you create clusters in the UI, the Clusters API, or the Jobs API (specified in the APIs as 9.1.x-photon-scala2.12).

Photon supports a limited set of instance types on the driver and worker nodes. Instance types with Photon consume DBUs at a different rate than the same instance type running a non-Photon runtime. For more information about Photon instance types and Photon DBU consumption, see the Databricks pricing page.
