December 3 Core Algorithm Update
Google has confirmed a core algorithm update which rolled out on December 3, 2020. The December update is the third core algorithm update this year. The first core algorithm update was January 13 and the second update was May 4, 2020
Later today, we are releasing a broad core algorithm update, as we do several times per year. It is called the December 2020 Core Update. Our guidance about such updates remains as we’ve covered before. Please see this blog post for more about that:https://t.co/e5ZQUAlt0G

Many websites inevitably noticed drops or gains in search rankings when the December 3 core update rolled out.
Interesting part is - the December 2020 Core Update contained the quality of seemingly non-observable changes which indicates that what has changed might have something to do with how Google understands web queries and web pages.
These days algorithm updates are an incremental opportunity for the algorithm to mature. I personaly believe that the December 3 algorithm has to do with future features and capabilities.
