Following up with Revit 2019.2 update install issues, there is another critical point that wasn’t documented. When you install Revit 2019.2, it silently updates your current Dynamo install to the 1.3.4 version.
As a general rule of thumb, Dynamo supports three versions of Revit: the current release (2019) and two versions back (2018 and 2017).
| Revit version | First stable Dynamo for Revit version | Last supported Dynamo for Revit version |
| 2013 | 0.6.1 | 0.6.3 |
| 2014 | 0.6.1 | 0.8.2 |
| 2015 | 0.7.1 | 1.2.1 |
| 2016 | 0.7.2 | 1.3.2 |
| 2017 | 0.9.0 | Latest Daily Build |
| 2018 | 1.3.0 | Latest Daily Build |
| 2019 | 1.3.3 | Latest Daily Build |
| 2019.2 | 1.3.4 | Latest Daily Build |
See the Dynamo primer for more info.
While the Revit 2019.2 & Dynamo 1.3.4 updates may not break your existing Dynamo workflows, it would be better for Autodesk to notify users of these hidden installations.
