Thank you very much for taking the time to reach the Intel® Communities Team.
Allow me to share with you that the BIOS version 0061 was removed since we are adding some adjustments to it. If you are not having any problems with the current version you have, do not downgrade and, please be monitoring the Intel® Download Center so when the 0061 version is ready to use you can perform the firmware update on your devices.
I hope this answers all your questions.
LOL! "Adjustments"; that's a hilarious description! Go anywhere on the web and they will tell you that the Spectre microcode fix was withdrawn by Intel (because it caused reboot problems, severely slowed 4th and 5th generation Core processors, etc. and etc.) and the BIOS releases containing this microcode were all correspondingly withdrawn as well.
What the next BIOS release will be called is not a question that anyone here can answer. When the microcode is fixed and an updated BIOS is released and made available, you will know when what the release number actually is. Stay tuned...
