Dec 09th, 2021: Version

  • Initial release of the LTS version of Rails 5.2.
  • This is identical to the official 5.2.6 release, except for the additional Rails LTS hardening config. This config currently has no effect but might be used for future fixes (in which case the advisory will point that out).
  • Supports Ruby 2.2, 2.5, and 2.7.
  • (Skipped to version .10 to avoid collision with a potential future community release.)
