Ruby Compatibility
- __callee__ now properly returns the name under which a method was
called, which will be the new name in the case of aliased methods. #2305,
#7702
- More use cases for keyword arguments have been fixed to behave
correctly and avoid extraneous warnings. #7637, #7645, #7657, #7658, #7670,
#7672, #7686
- Array#pack now supports more cases, passing nearly all specs. #7663
- Compatibility with CRuby’s command-line arguments has been improved.
#7678, #7680, #7681, #7681, #7683, #7684
Standard Library
- irb is updated to 1.4.2. #7690, #7691
- open-uri is updated to 0.3.0. #7701
- io-wait is updated to 0.3.0. #7701
- stringio is updated to 3.0.5. #7701
- strscan is updated to 3.0.6. #7701
- open3 is switched to using the gem at 0.1.2. #7701
Platform Support
- Exception backtraces now default to color output when the controlling
terminal is a TTY. Disable using -Xbacktrace.color=false or equivalent in
.jrubyrc. #7693
Performance
- String#split has been optimized to skip regular expression use for
simple split expressions. Simple ASCII strings also split faster. #7629
