Drupal8: composer requires psr/log ~1.0.0, incompatible with psr/log 1.1.0
I found this issue reported on Stack Exchange: https://civicrm.stackexchange.com/q/27832/12
civicrm-cxn-rpc both specify a dependency on
psr/log version 1.1 came out last month, and apparently some Drupal-related package already requires it.
There are only three commits' difference between 1.0.2 and 1.1.0, and one is in the README. I'm not a PSR-3 expert, but my sense is that we can change our composer dependencies to support the newer version.
