The JRuby community is pleased to announce the release of JRuby 1.7.1

JRuby 1.7.1 is our first update release since JRuby 1.7.0. The primary
goal of 1.7 point releases is to fill out any missing compatibility
issues with Ruby 1.9.3. The feedback we have gotten (along with
patches) has ended up being a subtantial release.

We also addressed security vulnerability CVE-2012-5370 and stopped
using MurmurHash2 as our hashing algorithm (now using same Hashing
algorithm as Perl). All users are recommended to upgrade to JRuby
1.7.1.

Changes of note:

- New hashing algorithm to address CVE-2012-5370
- Update standard lib to match MRI patchlevel 1.9.3p327
- Several fixes to new io/console.rb implementation
- system/spawn/popen fixes and additional options hash fixes
- Several SSL fixes (jruby-openssl release coming soon for 1.6.8 users)
- IO.select not erroneously reporting data to be read
- Psych YAML engine updated to latest
- 113 issues fixed since 1.7.0
