Does InfluxDB only run on Ruby 2+?

[stevebissett]

This has showed up in our CI package and it appears that only Ruby 2 is supported, but not mentioned as a requirement.

Yes, support for Ruby 2.0 was dropped in v0.2.0 of this gem. I've noticed though, that this isn't clearly communicated anywhere (except in the commit message):

Refactor library (prepare to 0.9 support)

• [...]
• Break support for Ruby < 2

ref #150, #148

How badly do you need support for Ruby 1.9? Since it looks like only #create_continuous_query relies on keyword arguments, I could refactor this as options={} argument (PRs welcome).

I'd prefer not to, though, but add a warning at the top of the README.

v0.3.4 is Ruby 1.9 compatible again and v0.3.3 is yanked from Rubygems.

I've also added a note in the README: I'll keep the 0.3.x releases compatible with Ruby 1.9, but expect this to change with v0.4.
