WR Switch firmware v7.0 release
Dear Rabbits, Following the months of preparation, the WRS firmware v7.0 is now released! We would like to invite you to download, validate it in your installations and ultimately update your switches with it.
WR Switch firmware v5.0.1 released
Since v5.0 was released we have found a few problems in the WR Switch software package. This new v5.0.1 release does not include new functionality but contains important hotfixes to the v5.0. The FPGA bitstream used in v5.0.1 is exactly the same as in 5.0, therefore those same calibration values apply. As for any other release, you can find all the links to download the firmware binaries and manuals on our v5.0.1 release wiki page
WR Switch firmware v5.0 released
The new stable release v5.0 of the WR Switch firmware comes this year as a Christmas present. As always, you can find all the links to download the firmware binaries and manuals on our release wiki page
