 * 2.1.182 -- 2023-09-29
   * Improved failure reporting: most failures now provide an additional message describing the failure as well as improving how the expected and actual values are displayed (primarily hiding `=?` and showing a more accurate/intuitive test form).
   * Update `deps.edn` to use `:main-args` (instead of `:main-opts`) for parameterized tasks in `build.clj` -- see [Running Tasks based on Aliases](https://clojure-doc.org/articles/cookbooks/cli_build_projects/)

+This runs _only_ tests marked as being `^:negative`.
 
 Leiningen's approach uses an additional layer in its `project.clj` file where you specify `:test-selectors` which are labels for predicates that run on the metadata of tests to determine whether to include them or not. Run `lein test help` for details. The equivalent of the above "humane" run would be:
