# Version Compatibility

Each version of ASEE Flow is bound to a specific version of the **External Task Clients**.

ASEE Flow and its compatible **Java** External Task Client always share the same version.

<table class="table table-striped">
  <tr> <th>ASEE Flow version</th> <th>NodeJS client</th> </tr>
  <tr> <td>7.15.x</td> <td>2.1.x</td> </tr>
  <tr> <td>7.16.x</td> <td>2.1.x</td> </tr>
  <tr> <td>7.17.x</td> <td>2.2.x</td> </tr>
  <tr> <td>7.18.x</td> <td>2.3.x</td> </tr>
  <tr> <td>7.19.x</td> <td>3.0.x</td> </tr>
  <tr> <td>7.20.x</td> <td>3.0.x</td> </tr>
  <tr> <td>7.21.x</td> <td>3.1.x</td> </tr>
  <tr> <td>7.22.x</td> <td>3.1.x</td> </tr>
  <tr> <td>7.23.x</td> <td>3.1.x</td> </tr>
</table>

Only these default combinations are recommended (and supported) by ASEE Flow. Nevertheless, each version of the External
Task Clients can be combined with newer patch versions of the ASEE Flow Workflow Engine.
