In version 3.9.0 we are introducing a new store format that will increase overall check performance.
Customers wanting to test out this new release can now download the first release candidate, version 3.8.1_04 from the Q-Portal.
Please make sure to read the (short) section about the upgrade in the installation instructions included with the checks, since the store files have to be converted before the upgrade. Also bear in mind that there is no way of converting the files back to the old format. When downgrading all store files have to be deleted beforehand (we know that this is generally no big deal).
