# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [4.0.0] - Unreleased
### Added
- New `transpile` command to replace some functionality of devel server

### Changed
- Major rewrite/refactor of `mothd`
  - There are now providers for State, Puzzles, and Theme. Sqlite, Redis, or S3 should fit in easily.
  - Server no longer provides unlocked content
  - Puzzle URLs are now just `/content/${cat}/${points}/`
- `state/until` is now `state/hours` and can specify multiple begin/end hours
- `state/disabled` is now `state/enabled`
- Mothball structure has changed substantially
  - Mothballs no longer contain `map.txt`
  - Clients now expect unlocked puzzles to just be `map[string][]int`

### Deprecated

### Removed
- Development server is gone now; use `mothd` directly with a flag to transpile on the fly

### Fixed

### Security

## [Unreleased]
### Changed
 - Endpoints `/points.json`, `/puzzles.json`, and `/messages.html` (optional theme file) combine into `/state`
 - No more `__devel__` category for dev server: this is now `.config.devel` in the `/state` endpoint
 - Development server no longer serves a static `/` with links: it now redirects you to a randomly-generated seed URL
 - Default theme modifications to handle all this
 - Default theme now automatically "logs you in" with Team ID if it's getting state from the devel server

## [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
### Added
- 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).
- A CONTRIBUTING.md to describe expectations when contributing to MOTH
- 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.
### Fixed
- Handle cases where non-legacy puzzles don't have an `author` attribute
- Handle YAML-formatted file and script lists as expected
- YAML-formatted example puzzle actually works as expected
- points.log will now always be sorted chronologically

- New `notices.html` file for sending broadcast messages to players
### Changed
- Use native JS URL objects instead of wrangling everything by hand
