Summary

Fixes #250

Checklist

• Added changelog entry (If there isn't an #unreleased section, add that and your changelog entry to the top of the changelog)

• Ran unit tests (rake test:unit):
  Note: to get the tests to run on Ruby 3.2 and 3.3, i had to temporarily remove the require "pry" line from spec/spec_helper.rb. That change is not part of this PR because its part of the larger issue of getting the tests working on modern, maintained Ruby versions. I also don't know if pry is still required for integration tests, so i didn't want to remove it. All unit tests passed on Ruby 3.2 and 3.3. Testing on Ruby 3.4 succeeded except for two trivial failures related to expecting the old representation of hashes (i.e. {:a => "b"} as opposed to {a: "b"}

• I alphabetized all attributes, parameters, and methods by name in any class file I changed

• I have linked the JIRA ticket in the summary section
