Product: Tarantool
Audience/target: anyone who is choosing the right Tarantool release for their project
Root document: TBA, maybe around release notes?
SME: @ Totktonada

Like this one: https://wiki.ubuntu.com/Releases

Can be included in #2218

Mention that support of 1.10 will be dropped with the 2.10–2.11 release (@ kyukhin's words).

Update after the issue was closed: further info will help you alter the calendar.
The calendar was done with the help of https://app.diagrams.net/ (former draw.io).
It uses the same font (VK Sans Text) and the same background color (F4F4F4) as our docs website.

The process is also described in our Notion: https://www.notion.so/tarantool/Release-notes-workflow-b4292dbf8fbd41d58a1983546de4a879#5510c37ce2824d93af662a95089db02e

I see the label "site", so what are we going to do:

• to add this diagram to the release page in documentation https://www.tarantool.io/en/doc/latest/dev_guide/release_management/
• or to place the diagram on some of the site page?
