Blackmagic has announced via 
its newsletter the discontinuation of the Micro Cinema Camera / Micro Studio Camera 4K production. The reason is the current global shortage of chips, which has already forced Sony to discontinue the Sony Alpha 7 II, Alpha 6100/6400 and PXW-Z190 www.slashcam.de/news/single/Sony-stellt-wegen-Chipmangel-die-Produktion-von-So-16908.html, among others.
Blackmagic does not say that the production stop is only temporary until the chip shortage is resolved, so it may be that this is the final end of the Micro Cinema Camera and Micro Studio Camera 4K, which are after all already 6 years old. Here is our test of the Micro Cinema Camera.
Blackmagic Newsletter Excerpt
Blackmagic advises Resolve update due to security vulnerability
.
Blackmagic also just announced via Twitter that there is a security vulnerability in older versions of DaVinci Resolve and therefore called all users to upgrade to the latest version 17.4 of Resolve or the current version 17.4.2, which is not affected by the problem.
Unfortunately, Blackmagic does not disclose any further information about the vulnerability (for example if every operating system is affected), so it is not clear how acute the problem is and how - apart from an update - the risk can be minimized.
It could be that Resolve (via Photon library) is also affected by the current Log4j problem forum.blackmagicdesign.com/viewtopic.php?f=21&t=152387&hilit=log4j, but then the current security problem would not have been fixed in the new version more than a month ago, so it is a different security problem.
