SCL packages (parallel installation of multiple versions)

  • 5.4.45: 10.4%
  • 5.5.33: 16.6%
  • 5.6.19: 41.5%
  • 7.0.4: 31.5%

Numbers for SCL are less interesting, as people usually use them to have multiple versions, often on development workstation, or to test new version, or to keep an old one for some legacy application.

Conclusion: usage of 5.4 is still too high for a dead version, even if I include  some security patches in my build (backported from 5.5), I very strongly recommend to upgrade to a maintained version, 5.5 (EOL in July 2016) or better 5.6 (EOL in December 2018).
