The JRuby community is pleased to announce the release of JRuby 9.2.10.0

- Homepage: [http://www.jruby.org/](http://www.jruby.org/)
- Download: [http://www.jruby.org/download](http://www.jruby.org/download)

JRuby 9.2.x is compatible with Ruby 2.5.x and stays in sync with C Ruby.  As always there is a mix of miscellaneous fixes so be sure to read the issue list below.  All users are encouraged to upgrade.

Ruby Core
------------------

* Kernel#send and BasicObject#\_\_send\_\_ will now honor refinements used in the surrounding scopes. ([#5945](https://github.com/jruby/jruby/issues/5945), [#6045](https://github.com/jruby/jruby/issues/6045))
* Kernel#eval will now honor refinements used in a given binding. ([#6017](https://github.com/jruby/jruby/issues/6017))
* Process#spawn now correctly processes environment variables for the child process. ([#3428](https://github.com/jruby/jruby/issues/3428), [#5907](https://github.com/jruby/jruby/issues/5907))

Ruby Standard Library
---------------------

* RubyGems has been updated to version 3.0.6. ([#5995](https://github.com/jruby/jruby/issues/5995), [#5996](https://github.com/jruby/jruby/issues/))
* The jruby-openssl library has been updated to 0.10.4. This release improves support for newer forms of ciphers and cryptographic keys and reduces the number of Java module warnings displayed. ([#6077](https://github.com/jruby/jruby/issues/6077))
* The compatibility of the fiddle library has been improved. ([#5955](https://github.com/jruby/jruby/issues/5955), [#5956](https://github.com/jruby/jruby/issues/5956), [#5960](https://github.com/jruby/jruby/issues/5960))

Java Support
------------

* Java methods looked up one-at-a-time using `java_method` and friends now honor Java modules. This fixes some
  illegal access errors introduced in JRuby 9.2.9.0. ([#5894](https://github.com/jruby/jruby/issues/5894), [#5969](https://github.com/jruby/jruby/issues/5969), [#6043](https://github.com/jruby/jruby/issues/6043), [#6069](https://github.com/jruby/jruby/issues/6069), [#6072](https://github.com/jruby/jruby/issues/6072))
* More illegal access warnings have been cleaned up in JRuby and the jruby-openssl extension.

Native FFI Improvements
-----------------------

* The native subsystem has been rebuilt on MacOS to avoid security warnings due to the old toolchain originally used to build it. ([#6044](https://github.com/jruby/jruby/issues/6044), [#6074](https://github.com/jruby/jruby/issues/6074))
* Native constants have been updated for Windows to better support the Ruby socket API. ([#5656](https://github.com/jruby/jruby/issues/5656), [#6070](https://github.com/jruby/jruby/issues/6070), [#6071](https://github.com/jruby/jruby/issues/6071))

Performance Improvements
------------------------

* Several improvements to the method invocation pipeline and JVM bytecode output to improve JIT optimizations. ([#5958](https://github.com/jruby/jruby/issues/5958), [#5959](https://github.com/jruby/jruby/issues/5959), [#5978](https://github.com/jruby/jruby/issues/5978), [#5992](https://github.com/jruby/jruby/issues/5992), [#6005](https://github.com/jruby/jruby/issues/6005))
* Several core methods used by Rails and the internal handling of exception backtraces have been optimized. ([#5952](https://github.com/jruby/jruby/issues/5952), [#5961](https://github.com/jruby/jruby/issues/5961), [#5965](https://github.com/jruby/jruby/issues/5965), [#5972](https://github.com/jruby/jruby/issues/5972), [#6014](https://github.com/jruby/jruby/issues/6014), [#6015](https://github.com/jruby/jruby/issues/6015), [#6031](https://github.com/jruby/jruby/issues/6031), [#6067](https://github.com/jruby/jruby/issues/6067))

JRuby Launcher
--------------

* Java options dotfiles accidentally omitted in the JRuby 9.2.9.0 release have been restored in the bin directory.
* The bash-based launcher script has been cleaned up and optimized for cross-platform compatibility. ([#5977](https://github.com/jruby/jruby/issues/5977), [#6007](https://github.com/jruby/jruby/issues/6007), [#6016](https://github.com/jruby/jruby/issues/6016))
