[sr-dev] git:5.2:ca470cb6: pv: add $def pseudo variable

[Juha Heinanen]

Many of today's commits by Sergey Safarov seem to add new features to stable
release, for example:

  Module: kamailio
  Branch: 5.2
  Commit: ca470cb6c5f341c518b208e8e595be2ed1309802
  URL: https://github.com/kamailio/kamailio/commit/ca470cb6c5f341c518b208e8e595be2ed1309802

  Committer: Sergey Safarov <s.safarov at gmail.com>
  Date: 2019-03-30T15:08:50+03:00

  pv: add $def pseudo variable

Could someone explain what is going on?  Has the "bug fixes only" policy
regarding stable releases been relaxed?
