## [v4.0.3] - 2020-03-02
### Added
- `transpile` now has a `markdown` command,
  so you can use the "stock" markdown formatter

### Changed
- event.log is now events.csv, to make it easier to import to a spreadsheet
- When in devel mode, any team ID may score points. This allows more interaction with the state directory.
- When in devel mode, any team ID may be registered.
  It still works the same way if you register a team in `teamids.txt`,
  but now you can use anything and it will put you on an already existing team
  named `<devel:$ID>`.
- switched from `blackfriday` to `goldmark`, to support CommonMark
- `puzzle.json`no longer has `Pre` and `Post` sections

### Fixed

### Security

## [v3.5.1] - 2020-03-16
### Fixed
- Support insta-checking for legacy puzzles

## [v3.5.0] - 2020-03-13
### Changed
- We are now using SHA256 instead of djb2hash

- URL parameter to points.json to allow returning only the JSON for a single
  team by its team id (e.g., points.json?id=abc123).

- Include basic metadata in mothballs
- add_script_stream convenience function allows easy script addition to puzzle
- Autobuild Docker images to test buildability
- Extract and use X-Forwarded-For headers in mothd logging
- Mothballs can now specify `X-Answer-Pattern` header fields, which allow `*`
  at the beginning, end, or both, of an answer. This is `X-` because we
  are hoping to change how this works in the future.
