The update simplifies accessing environment keys and role warnings in Supabase clients by moving them to new functions 'getSupabaseClientKeys' and 'getServiceRoleKey'. The redundancy in the code is reduced promoting clearer and more maintainable code. The '@epic-web/invariant' import has been removed from files as it is no longer needed.
The commit encompasses the aspect of refactoring the i18n handling for language cookies and headers. It also includes the deletion of get-language-cookie file and its transformation into a function inside i18n.server file. Extra functionalities were added to the i18n.server like enhancing the i18n server instance creation to consider the 'accept-language' header and default to environment provided values when necessary. The changes were also adjusted accordingly on the packages/i18n/package.json where deletion of "./cookie" was realized.
