From the BrowserMap Github page:
BrowserMap has been donated to the Apache Software Foundation, as a
client-side module of the Apache DeviceMap project. Until the full
integration is completed fixes will be pushed to both code repositories.
Once BrowserMap is fully migrated the development will continue solely on
ASF’s infrastructure.
