Codership is please to announce a new release of Galera Manager. The current installer stands at version 1.14.0 ((you can check this by typing: ./gm-installer version which will report gm-installer version 1.14.0 (linux/amd64)) and the actual Galera Manager GUI is at version 1.8.6. Users ill notice usability improvements, and fixes for issues filed at the galera-manager-support issue tracker.

One notable change that will affect users is the removal of support for CentOS 7. Please read What to know about CentOS Linux EOL by Red Hat. From an installer standpoint, one will note the supported OSes have it removed too:

./gm-installer version --list-supported-oses
gm-installer version 1.14.0 (linux/amd64)
Supported OSes:
	centos:7:	deprecated
	debian:10:	deprecated
	debian:11:	active
	debian:12:	active
	redhat:8:	active
	redhat:9:	active
	ubuntu:20.04:	active
	ubuntu:22.04:	active

A common feature request is version pinning. Before this release, when you installed, say MySQL 8.0.35 and you wanted to add a new node, and the latest release is now 8.0.37, you would find that the new node would not be on 8.0.35 but on 8.0.37 – this is subpar and would force you on an upgrade path. Version pinning ensures that you get 8.0.35, and upgrade when you chose to!

For those that utilise Percona XtraDB Cluster (PXC), it also works with Red Hat Enterprise Linux 9, now.

A few notes from the internal changelog that is published in the application (and also on the Galera Manager Changelog):

• 1.8.6
• fix: fix RHEL 9 compatibility with PXC 8
• misc: remove CentOS 7 support due to EOL
• fix: re-enable wsrep_status_file
• 1.8.5
• feature: pin mysql/mariadb/pxc dependencies to the actual version
