perfSONAR 4.1 is now available for download. Note that you may not see the new packages on your system right away as not all mirrors have synced, but the packages should be propagating throughout the day.

 perfSONAR 4.1 contains a number of changes including:

- A new component called pSConfig to replace the MeshConfig component
- A new TWAMP tool
- Support for docker containers of the “tools" and “testpoint" bundles

For a full list of changes see the release notes here:

Also note that we are not making 4.1 available on CentOS 6 or Debian 7 (wheezy) since both of these OSes are nearing (or at) their provider's support end of life date. We strongly recommend you update to a supported operating system as soon as possible. Also, BWCTL is not included by default for fresh installs of 4.1, though it will be left untouched on existing systems. For more details on the upgrade process including information about discontinued operating systems, deprecation of BWCTL and exact details of the MeshConfig to pSConfig transition see

If you are running a supported operating system and have auto-updates enabled, you should get the new version automatically within 48 hours. There are no manual steps required and all data should be preserved. If you do not have auto-updates enabled, see for details on updating on your chosen OS.

Also, if you are looking for the latest ISO images to perform a new install you can find links to them here:

Thank you again to all the beta testers that have experimented with the software. Your feedback is crucial to a smooth and successful release. Please let us know if you have any questions about the release. 

Thank you,
The perfSONAR Development team
