Tungsten Clustering 7.1.4

Build: 10

Release Date: 1 Oct 2024

End of Life Date: 7 Jul 2026

Release 7.1.4 contains a number of key bug fixes and improvements.

Warning

Due to JGroup libraries being updated in the 7.1.0 release, managers running releases older than 7.1.0 will not communicate with managers running 7.1.0+ therefore when upgrading to this release from anything older than 7.1.0, all nodes must be upgraded before proper cluster communication will be restored. Ensure the cluster is in MAINTENANCE before beginning the upgrade and do NOT SHUN nodes whilst a mix of manager versions are running.
