 This library aims to support and is [tested against][travis] the following Ruby
 versions:
 
-* Ruby 1.8.7
-* Ruby 1.9.3
 * Ruby 2.0.0
 * Ruby 2.1
 * Ruby 2.2
-* JRuby 1.7 (Both 1.9 mode and 1.8 mode)
+* Ruby 2.3

 If something doesn't work on one of these versions, it's a bug.
 
 This library may inadvertently work (or seem to work) on other Ruby versions,
 however support will only be provided for the versions listed above.
