Sprint Quilava Release Note

The release for Project Clearwater sprint “Quilava” has been cut. The code for this release is tagged as release-110 in GitHub.

In this release we:

  • Upgraded the version of Cassandra that runs with Project Clearwater to 2.1.15.
  • Enhanced the Project Clearwater BGCF to route based on the phone number in the request URI if the request URI represents a phone number and no routing number parameter is present.

This release also includes the following bug fixes:

As mentioned above, as part of this release we are upgrading to Cassandra 2.1.15. To upgrade an existing deployment you must therefore follow the one-time extra upgrade steps below:

  • Before upgrading, on each node running Cassandra, run “/usr/share/clearwater/bin/run-in-signaling-namespace nodetool upgradesstables”. The nodes that run Cassandra are Homestead, Homer, and Memento (which can be run on a Sprout node).
  • Upgrade all nodes as normal, following the instructions at http://docs.projectclearwater.org/en/stable/Upgrading_a_Clearwater_deployment.html.
  • After upgrading, on each node running Cassandra, run “/usr/share/clearwater/bin/run-in-signaling-namespace nodetool upgradesstables”

If you are deploying an all-in-one node, the standard image (http://vm-images.cw-ngv.com/cw-aio.ova) has been updated for this release.
