JetBrains License Server is a web application that enables administration of floating licenses. The new license server features a fully revised user experience including easier installation, integration with the JetBrains Account service for license management, and a new communication protocol between the product and the license server.
What is going on?
Starting with the 2018.2.1 release of JetBrains IDEs (to be released in Q3 2018) and 2018.3 release of .NET tools (to be released in Q4 2018), products will no longer obtain license tickets from the old versions of JetBrains license servers (versions prior to #16429 which was released on March 19, 2018).
If you are currently using an outdated license server, you should update it to the latest version.
Please note that if you are using a product version older than 2018.2.1 (for IDEs) or 2018.3 (for .NET tools), it will be still possible to use an old license server.
Am I affected?
If you are using a JetBrains license server prior to version #16429 (released: March 19, 2018), you will be affected.
To find the version number of the license server you are using, look in the license server log or in the web interface.
Alternatively, all clients (JetBrains IDEs since version 2018.1 and .NET tools since the upcoming version 2018.2) that obtain license tickets from an outdated license server will show a notification indicating that an outdated license server is being used:
What do I need to do?
Please update the license server to the latest version by following the upgrade procedure described in the documentation.
Your JetBrains Account profile should be authorized to use a JetBrains license server. Please contact JetBrains Sales if you need any assistance with such authorization. If you are not sure whether you have obtained such permission before, we recommend that you reach out to us anyway so that we can minimize any possible downtime of the license server while the authorization is being granted.
Should you have any questions or requests about old license servers, please contact us by completing the form on the deprecation notice page for quick assistance or contact License Server support via firstname.lastname@example.org.
