• Use utf8mb4 by default in database options.
• Added goyave.ValidationStatusHandler(), a status handler for validation errors. Therefore, the format in which validation errors are sent to the client can be customized by using your own status handler for the HTTP status 400 and 422.
• Cache the regex used by helper.ParseMultiValuesHeader() to improve performance. This also improves the performance of the language middleware.
