After updating to 12 and 13, I'm getting unmatched params on the following route: ``` $stateProvider.state('record', { url: '/record/{appId}/{recordId:[0-9a-fA-F]{10,24}}', params: { appId: { value: null }, recordId: { value: null } }, views:{ '': { controller: 'RecordCtrl', templateUrl: 'app/record/record.tpl.html' } } }); ``` when I goto a url like: ``` <a href="/myapp/record/546a3e4dd273c60780e35df3/"> ``` per @christopherthielen this is because of the trailing slash introduced in the new version.
