RHSCL 2.2 was released recently [1] and this release includes several new collections:
rh-mariadb101 rh-postgresql95 rh-maven33 rh-mongodb30upg rh-mongodb32 rh-python35 rh-nodejs4 rh-ruby23 rh-ror42
SRPMs were taken and rebuilt for CentOS users in cbs.centos.org by SCLo SIG group. The packages are now available in the testing repositories via:
sudo yum install centos-release-scl sudo yum-config-manager --enable centos-sclo-rh-testing sudo yum install rh-mariadb101
They will be soon moved to mirrors, but in case there are some issues, let us know.
Please, mind, that these packages are not meant to be used on RHEL. On RHEL you can acquire the packages as documented at [1].
