Orc 2.1.2 is an update of the Orc implementation. This release makes no language changes. The release updates Orc's major dependencies:

  • Scala (2.12) (necessary JARs are bundled with this release)
  • Java SE (8)

Also, the Orc Eclipse plug-in is updated to be fully Eclipse Neon 4.6 compatible, and no longer uses the now-defunct Eclipse IMP runtime.

This release requires Java SE 8.

See our Downloads page for detailed instructions on how to download and use Orc within Eclipse, locally within your Web browser, or from the command line.
