Earlier this week, we released the latest v9.90 CPU client after almost 3 weeks
of testing. While it initially seemed to be working fine, a number of errors started
accumulating over the last 24 hours. We've identified a server configuration issue
and believe it is now fixed as of 6AM UTC today. The server was generating
invalid WUs for the MLDS queue. We've cancelled all of the problematic WUs
and are adding new ones to the main queue. The GPU clients and MLDSTEST
queue remained unaffected.

v9.90 is an important release for MLDS, as it contains support for CNNs and Dense
feed forward network types needed for DS4. Highlights include:


    - Statically linked binary for Linux (no more AppImage)
    - DS4 support! (CNN and Dense networks)
    - Better NaN handling
    - Update to libTorch 1.9
    - Wrapper instead of BOINC native API



Our apologies for the bumpy rollout, but if you've had issues with computation errors
earlier this week, please retry at your earliest convenience, and post any issues
to our forums or our Discord server.
