Joris Kohl van Wijngaarden delivered a Dutch localization enhancement for the streamyfin/streamyfin repository, focusing on updating the nl.json file to improve translation accuracy across user interface elements. By adding and refining key-value pairs in JSON, Joris addressed issues of localization drift and ensured that Dutch translations more closely matched the intended user experience. The work centered on localization best practices, laying a foundation for future internationalization efforts within the project. While the scope was limited to a single feature over one month, the update enhanced maintainability of localization assets and prepared the codebase for broader language support in upcoming releases.
