Bequant releases R5.0.2, with minor fixes and additions over the initial R.0 release (R5.0.1):

- Added a column to the Status->Subscribers->Groups table, with the number of warnings for each group. This column can be used as a sorting criteria, to see which groups have triggered more warnings.

* Fixed a problem changing the configuration of TCP initial window.

* Improvements in subscriber-group shaping, which will now kick in at 90% of rate limit, instead of at 75%.

* Added hostname to cluster ID when selecting nodes, when shutting down, rebooting, generating diagnostic files, installing license or installing software.

* Fixed Statistics->DoS->SYN-Attacks table, not showing duration of attacks.

* Fixed live DPI in subscriber dashboard, not reacting to changing both directions to uplink or downlink.
