 ### Added
 
 -   Integration tests via GHA (non-user endpoints)
+-   Unit tests for new releases, passing limit parameter with minimum and maximum values of 1 and 50
+-   Unit tests for categories, omitting country code to test global releases
 
 ### Fixed
 
 -   Incorrect category_id input for test_category
 -   Assertion value for test_categories_limit_low and test_categories_limit_high
 -   Pin Github Actions Runner to Ubuntu 20 for Py27
+-   Fixed potential error where `found` variable in `test_artist_related_artists` is undefined if for loop never evaluates to true
+-   Fixed false positive test `test_new_releases` which looks up the wrong property of the JSON response object and always evaluates to true
