There was a problem hiding this comment.
this change does not look strongly related to the training version.
It would be worth to mention it in the PR description, if so.

It depends how you look at it. The new training was done with a reduced cut value, it also had to be changed in the release.
I updated the PR description.

This pull request is fully signed and it will be integrated in one of the next CMSSW_8_1_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @slava77, @davidlange6, @smuzaffar |

The updated training was announced in slide 7 of the News slides in the b tag meeting during the June CMS Week (https://indico.cern.ch/event/543002/contributions/2205056/attachments/1295645/1932587/BTV_news_2016_06_21.pdf).
The performance is slightly improved wrt the old training v2 training produced in the 74X release cycle. In addition, for CA15 jets the dR(SV,jet) cut used to associated secondary vertices to jets was reduced from 1.3 to 1.0 in order to reduce the fake rate and consequently improve the overall performance.
