I regenerated the code using openapi-generator v7.17.0.
With the new version of openapi-generator, responses are specified easier (see /lib/API/) by using handleResponseWithDataType(). Additionally, all generated files are output in PHP 8.1 Which means that some parameters now have types. Since php-modrinth-api specifies PHP 8.1 or higher in the composer.json anyway, this should not be a breaking change.

There have also been some changes to Modrinth's openapi.yaml:

• Add ability to delete user icon #3383
  • New operation id: deleteUserIcon for /user/{id|username}/icon
• Document usage of OAuth #3342
• Clarify date timestamps in search docs #4293
• update openapi docs to include neoforge for forgeUpdates #4545
