Make sure to update your themed less file with the latest version. In the upcoming 1.2.x releases we'll split the 'theme' less file into multiple files, to simplify this process.
There were also many view file updates this release, please check changes (e.g. diff) of your themed versions. We are constantly reducing view complexity to ease this process.
Important changed views:
- Logins (Standalone / Modal)
