The JRuby community is pleased to announce the release of JRuby 9.3.3.0

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

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)

The JRuby community is pleased to announce the release of JRuby 9.3.2.0

Homepage: https://www.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.

Security

Date-parsing methods have been modified to accept an input-size limit option. This addresses CVE-2021-41817. It was originally reported against Ruby's C-based date extension, which JRuby does not use, but JRuby's own implementation of date is also affected by the same issue.

The fix is detailed in #6952. A workaround is provided, via patching the pure-Ruby date code in your own JRuby install. Rebuilding JRuby is not necessary. This PR is the only functional difference from JRuby 9.3.1.0.
In order to match Ruby behavior and permit interrupting these date-parsing regular expression matches, this release also enables interruptible regular expressions globally. This feature can be disabled using the "regexp.interruptible" JRuby option as described in the above PR.

Performance

The performance of Time#strftime has been greatly improved (3.5x-5.8x faster). (#6942, #6956)

Native Integration

The jffi library on MacOS has been updated to sign the native library, allowing it to load properly on Apple Silicon. This improves compatibility on Apple's AArch64 systems (M1 and friends). (jnr/jffi#116, jnr/jnr-ffi#257)

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.

This is a security release to address CVE-2021-41817. It was originally reported against Ruby's C-based date extension, which JRuby does not use, but JRuby's own implementation of date is also affected by the same issue.

The issue affects calls to various Date and DateTime parsing methods with extremely long strings. The regular expressions associated with these methods may run much longer than desired or never return.

The fix is detailed in #6951. A workaround is provided, via patching the pure-Ruby date code in your own JRuby install. Rebuilding JRuby is not necessary. This PR is the only functional difference from JRuby 9.2.20.0.

We recommend that all JRuby 9.2 users upgrade.

#6951 - Limit Date.parse input length and make interruptible

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.

Compatiblity

Argument-count errors will now produce a more accurate backtrace. (#6335, #6768, #6771, #6846, #6928)

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)

The JRuby community is pleased to announce the release of JRuby 9.3.0.0

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.

With such a long development cycle, there are bound to be "dot zero" bugs and compatibility gaps, so we plan to release incremental fixes for JRuby 9.3 rapidly. We encourage users to file issues for any problems they encounter and join us in our Matrix chat room

Thank you to our excellent community of users for their many contributions!

Compatibility

Ruby language compatibility is updated to match Ruby 2.6.8. (#5576)
The require/load/autoload subsystem has been rewritten to better match Ruby behavior. This improves support for the Zeitwerk loader and fixes many long-standing issues. (#2794, #3656, #5403, #5466, #5590, #5618, #5638, #5717, #5763, #5764, #6347, #6445)
Improved logic for handling complex method and constant lookups, such as when prepends, refinements, or super calls are in play. Most known issues with these forms have been fixed. (596, #2155, #4678, #6271, #6712, #6777, #6778, #6785)

Standard Library

The standard library has been updated to match Ruby 2.6.8. Several libraries now use the official gems, allowing them to be upgraded independently of JRuby. (#4875, #6150, #6797, #6796, #6795, #6794, #6533, #6802)

Java Integration

JRuby supports Java versions 8 through 17, and should work well with any supported build of OpenJDK. Future versions of JRuby may drop support for Java 8 through 10, so we encourage users to upgrade older apps soon.
The Java integration logic for extending Java classes from Ruby has been rewritten to better support Java constructors and to reuse more logic from the rest of our Java integration library. This allows users to use those Ruby subclasses with Java frameworks that bootstrap using reflection, such as JavaFX. (#449, #2369, #4165, #5270, #6422)
JRuby now ships a new "jruby-base" jar artifact to Maven Central. This artifact provides a bare-bones JRuby jar file with no dependencies or standard libraries included. We may deprecate and remove the "jruby-core" artifact in the future, as it only provides Java dependencies and no standard libraries (users should prefer to build their own with jruby-base or use the jruby-complete artifact). (#6233)
