0.6.8 breaks coursier

[nafg]

In 0.5.2 everything was fine. After switching to 0.6.8, with coursier enabled, updateSbtClassifiers complains:

2 error(s):

Indeed,

$ coursier fetch 'org.webjars.npm:lru-cache:[2.7.0,3)'

Error:
  org.webjars.npm:lru-cache:[2.7.0,3):
    not found: /home/naftoli/.ivy2/local/org.webjars.npm/lru-cache/[2.7.0,3)/ivys/ivy.xml
    No version found for [2.7.0,3)

However,

$ coursier fetch org.webjars.npm:lru-cache:2.7.0
/home/naftoli/.coursier/cache/v1/https/repo1.maven.org/maven2/org/webjars/npm/lru-cache/2.7.0/lru-cache-2.7.0.jar

So apparently Coursier can't handle version ranges.

Do you have any idea what's pulling in lru-cache, and why only in updateSbtClassifiers?
