(Note that there is no v1.5.0 release. was prepping this release and found some more changes to make. So v1.5.1 is the first release for the v1.5.x series)
- Fixed a regression that happened when numeric translation keys contained leading zeros: #456 / #457
- Removed support for Ruby versions older than 2.3. Ruby 2.2 is now 4 years old. Applications have had ample time to upgrade, and if they haven't done so, now is an opportune time to do so.
- Removed some code that was checking for
RUBY_VERSION <= 1.9 - Began testing over Ruby 2.6.
