Support status
The main module functionality is stable. Maintenance is lagging (because volunteer driven), but this is not known to affect the majority of projects using it.
In case of needs that go beyond anything that should be handled in the issue queue: feel free to send the main maintainer a message.
As of 2025: 7.x releases have been removed from the project page, but there still is some level of support for 7.x-1.x issues in this issue queue, per D7Security group practices.
