Some outdated limits?

[trwnh]

For example:

Your display name is limited to 30 characters, your bio to 160. Avatars and header pictures can be uploaded as png, gif or jpg images and cannot be larger than 2MB. They will be resized to standard sizes - 120x120 pixels for avatars, 700x335 pixels for header pictures.

Hasn't the avatar limit been raised since some while ago? Also, I'm fairly sure some other limits have been added/updated, IIRC from keeping up with reading merged PRs. Numerical limits should be updated in documentation as well, and perhaps one additional .md doc should be created to list all numerical limits in one place, for convenience?
