Where do I get Galera 26 or 27?

[5lava]

Hello,

I’m trying to make Galera work on Percona XtraDB Cluster 5.7.16-27.19.
Quote from the Blog:
— wsrep API version 26
Quote from Release Notes:
— wsrep API version 27
PXC version number itself (5.7.16-27.19) suggests it’s 27.

Okay, but… where do I download any of them? Galera 26 or 27?
Most recent wsrep API version that I could find at Galera’s official website and Codership’s github is 25.
Please help me understand how do I get a proper version of Galera.
So far I’m stuck with
Thank you.

How are you installing the packages? And what OS are you running? For what it’s worth the installation instructions are here - https://www.percona.com/doc/percona-xtradb-cluster/5.7/install/index.html

Ok, I think I found it. Corresponding Galera versions live in Percona’s github at https://github.com/percona/galera.

5lava, please note that Percona makes independent PXC releases from Codership’s Galera Cluster, and there are some code changes unique to Percona in PXC. The ‘25’ or ‘26’ is not Galera library version, but the wsrep API interface numeration. In Percona we added some some new functions, hence we bumped the version. So in last PXC 5.6 it is ‘26’ and in PXC 5.7 it is ‘27’, while you may find ‘25’ in similar Codership releases.
The Galera library version is “3.19” as in https://www.percona.com/doc/percona-xtradb-cluster/5.7/release-notes/Percona-XtraDB-Cluster-5.7.16-27.19.html
