[NikitaZotov]

Is your feature request related to a problem? Please describe.
The documentation must record the history of development and operation, the current state and planning of the machine. To this end, it is necessary to add the ability to automatically change this part of the documentation.

Describe the solution you'd like
I think there are needed to record:

• PRs merges;
• Changelog changes;
• Questions solvings and applyings;
• Plans;
• Calls and speaks.
