Standard Library

• jruby-openssl has been updated to 0.11.0, which includes fixes for expired and replaced certificate verification. (#6871, #6909)

Native Integration

• The built-in FFI library has been updated to match the FFI gem, and can now be upgraded independently of JRuby. (#6732, #6747)
• FFI-based core methods on Windows and Solaris have been modified to delay activating FFI until after RubyGems has loaded any upgrades. (#6751, #6760, #6762)

Java Integration

• Nested jar files (jars packaged within another application jar) should load more quickly with caching improvements. (#6730, #6734, #6740)
