Dynamo 2.0.0 and 2.0.1 - What's New and What's Different

Nick SipesSeptember 18th, 2018

Dynamo 2.0 has been out for about 4 months now. Because this was such a major revision to the software, we wanted to allow some time prior to writing a post on what to expect.

Dynamo 2.0.0

Dynamo 2.0.0 was released on April 16, 2018, to much excitement. Okay, maybe just excitement to those of us that follow this stuff.

File Format

Dynamo 2.x came with a change in file format. Dynamo 1.x dyf and dyn files are saved in xml file format. Dynamo 2.x dyf and dyn files are saved in json file format. 1.x files can be upgraded to 2.x, however, there is no going back so make sure you do not overwrite your old files.


Most of the Graphical User Interface remains unchanged, with the exception of the Library. The library went through a major redesign. Nodes got moved around, some nodes changed names, and many redundant nodes were removed.

However, the biggest change is that Package Libraries have been separated from the out of the box libraries.

These are new and we should all be very excited!

Dictionaries are a specific data structure that consists of a "Key" and a "Value." Each "Key" has to be unique and has to be a string. This means we no longer need to create complicated "Get item at index" strings of code in order to compare to similar items.

Fast Forward to Today

Hot Fix

Since the initial launch of Dynamo 2.x, Dynamo 2.0.1 hot fix was released. This resolved most of the installation problems, as well as conflicts between Dynamo and other software. Additionally, it adds a few features back that were inadvertently removed. For more information, see our post: "Dynamo 2.0.1 and Revit 2019.0.1 Updates."


Not all of the packages we know and love have been release and noted to work completely with Dynamo 2.0. package has been released for Dynamo 2.x, as well as Clockwork 2.x.

Fortunately, you can install 1.x packages in 2.x. However, be warned that all the nodes may not work.


Dynamo now supports extensions. They are similar to add-ins and provide additional functionality, such as the ability to search a graph for a specific node. These are still rare to find, but thanks to a recent update, developers can now include them in the package manager.
