The JRuby community is pleased to announce the release of JRuby 9.3.3.0
- Homepage: https://www.jruby.org/
- Download: Downloads — JRuby.org
JRuby 9.3.x is compatible with Ruby 2.6.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.
The big news this release is support for Apple’s M1 family of processors
(Apple Silicon) via an update to our native FFI backend library. Nearly all
our usual test suites are passing on M1 and we have added a self-hosted CI
runner thanks to MacStadium’s OSS program. Callbacks from C to Ruby are
unsupported, but this does not affect any libraries we ship. We will
continue to improve M1 support with your help and bug reports.
We encourage users to file issues first and ask questions later! Please
join our Matrix room if you have any issues or just want to get involved.
Thanks to our contributors this cycle for helping to improve compatibility:
@ahorek, @byteit101
Additional thanks to @kovyrin for working through M1 issues with us and
confirming that a large application builds and tests successfully.
Hardware Support
This release includes greatly improved support for Apple Silicon
processors like the M1. (#6813, #6853, #6974, #6977, #6983, #6986, #7006)
Known issue: passing a Ruby FFI Function object to C code as a callback
is not currently supported due to security restrictions on Apple Silicon.
Neither JRuby nor any libraries we ship require this functionality. We will
fix it for a future release. (#6995)
Ruby Compatibility
The parser once again handles files larger than 32k lines. This issue
affected simplecov and mailer gems that we know of. (#6984, #6991)
Standard Library
ostruct is updated to 0.5.1, which fixes warnings in verbose mode
loading the json library. (#6831, #6963)
Java Integration
Additional fixes for super calls from Ruby subclasses of Java classes
to match behavior in 9.2.x. (#6935, #6957)
