- > Please read *Changed* for the changes to `comment_locations`.
- Added basic 2FA support however, Instagram has changed something and it will not work.

Changed
- Changed `comment_locations` to `comment` with a `type` argument.
- Moved all `like_*` functions to a single `like` function with a `type` argument.
- Moved all `follow_*` functions to a single `follow` function with a `type` argument.
- `follow` is all self-contained meaning it will call itself for all functionality.
- Improved all imports (x2).

Fixed
- Fixed an issue in `follow_likers` that would cause a crash.
- Following users may result in an output: `[ERROR]: Failed to follow user: x`.
- This may mean the user has a private account and the follow is requested.
- This will be improved later.

Changed
- Changed `medias_username` to stop any chance of causing a crash.

Added
- Added `like_feed`.
