 ### Added
 - `activeMonth` and `activeHalfyear` fields in NodeInfo usage.users object

+- `ForceMentionsInPostContent` MRF policy
 - AdminAPI: allow moderators to manage reports, users, invites, and custom emojis
 - AdminAPI: restrict moderators to access sensitive data: change user credentials, get password reset token, read private statuses and chats, etc
