-# 3.2.0 - Internal refactor, more subcommand types, and more command type guards (2021-??-??)
+# 3.2.1
+- `vaporwave`: Transforms input into full-width text
+- `eco post`: A play on `eco get`
+- `admin set prefix <prefix> (<@bot>)`: Allows you to target a bot when setting a prefix if two bots have conflicting prefixes
+- `party`: Sets the bot's status to streaming with a certain URL
+- `eco award`: Awards users with Mons, only accessible by that person
+- `thonk`: A result can now be discarded if the person who called the command reacts with ❌
+- `scanemotes forcereset`: Removes the cooldown on `scanemotes`, only accessible by bot support and up
+- `urban`: Bug fixes
+- Changed `help` to display a paginated embed
+- Various changes to core
+	- Added `guild` subcommand type (only accessible when `id: "guild"`)
+	- Further reduced `channel.send()` to `send()` because it's used in *every, single, command*
+	- Added a `RestCommand` type, declaratively states that the following command will do `args.join(" ")`, preventing any other subcommands from being added
+	- Is no longer lenient to arguments when no proper subcommand fits (now it doesn't silently fail anymore), you now have to explicitly declare a `RestCommand` to get an arbitrary number of arguments
+
+# 3.2.0 - Internal refactor, more subcommand types, and more command type guards (2021-04-09)
 - The custom logger changed: `$.log` no longer exists, it's just `console.log`. Now you don't have to do `import $ from "../core/lib"` at the top of every file that uses the custom logger.
 - Utility functions are no longer attached to the command menu. Stuff like `$.paginate()` and `$(5).pluralise()` instead need to be imported and used as regular functions.
 - The `paginate` function was reworked to reduce the amount of repetition you had to do.

 For common use cases, there wouldn't be a need to go accept numbers of different bases. The only time it would be applicable is if there was some sort of base converter command, and even then, it'd be better to just implement custom logic.
 
+## User Mention + Search by Username Type

+While it's a pretty common pattern, it's probably a bit too specific for the `Command` class itself. Instead, this pattern will be comprised of two subcommands: A `user` type and an `any` type.
