RHSCL 2.3, which was released recently [1], includes several new collections. 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 e.g.: sudo yum install centos-release-scl sudo yum-config-manager --enable centos-sclo-rh-testing sudo yum install rh-mysql57 --nogpgcheck The following collections are now available for testing: devtoolset-6 rh-git29 rh-mysql57 rh-perl524 rh-php70 rh-redis32 They will be soon moved to mirrors, but in case there are some issues, let us know on sclorg at redhat.com. Please, mind, that these packages are not meant to be used on RHEL. On RHEL, you can acquire the packages following the documentation at [1]. We still haven't finished rebuilding of the following two new SCLs that are part of RHSCL 2.3: rh-thermostat16 rh-eclipse46 [1] https://access.redhat.com/documentation/en-US/Red_Hat_Software_Collections/2/html-single/2.3_Release_Notes/ Regards, Honza
