Thank you to our contributors this release, you help keep JRuby moving forward! @​evaniainbrooks, @​kares, @​chadlwilson, #jimtng

Compatibility

• Fixed: Two bugs in the JIT compiler that broke certain super calls and defined_method yields. (#​8944, #​8946, #​9310, #​9349)
• Fixed: Fiber#raise left the fiber in an resumable state by not correctly transfering control. (#​9297, #​9356)

Platform Integration
