 # Rojo Change Log
 
 ## Current Master
-* *No changes*
+*No changes*
+
+## 0.4.0
+* Protocol version 1, which shifts more responsibility onto the server
+	* This is a **major breaking** change!
+	* The server now has a content of 'filter plugins', which transform data at various stages in the pipeline
+	* The server now exposes Roblox instance objects instead of file contents, which lines up with how `rojo pack` will work, and paves the way for more robust syncing.
+* Added `*.model.json` files, which let you embed small Roblox objects into your Rojo tree.
+* Improved error messages in some cases ([#46](https://github.com/LPGhatguy/rojo/issues/46))
+
+## 0.3.2
+* Fixed `rojo serve` failing to correctly construct an absolute root path when passed as an argument
+* Fixed intense CPU usage when running `rojo serve`
+
+## 0.3.1
+* Improved error reporting when invalid JSON is found in a `rojo.json` project
+	* These messages are passed on from Serde
 
 ## 0.3.0
 * Factored out the plugin into a separate repository

+# Rojo Design - Protocol Version 1
+This is a super rough draft that I'm trying to use to lay out some of my thoughts.
+
+## API
+
+### POST `/read`
+Accepts a `Vec<Route>` of items to read.
+
+Returns `Vec<Option<RbxInstance>>`, in the same order as the request.
+
+### POST `/write`
+Accepts a `Vec<{ Route, RbxInstance }>` of items to write.
+
+I imagine that the `Name` attribute of the top-level `RbxInstance` would be ignored in favor of the route name?
+
+## CLI
+The `rojo serve` command uses three major components:
+* A Virtual Filesystem (VFS), which exposes the filesystem as `VfsItem` objects
+* A VFS watcher, which tracks changes to the filesystem and logs them
+* An HTTP API, which exposes an interface to the Roblox Studio plugin
+
+### Transform Plugins
+Transform plugins (or filter plugins?) can interject in three places:
+* Transform a `VfsItem` that's being read into an `RbxInstance` in the VFS
+* Transform an `RbxInstance` that's being written into a `VfsItem` in the VFS
+* Transform a file change into paths that need to be updated in the VFS watcher
+
+The plan is to have several built-in plugins that can be rearranged/configured in project settings:
+
+* Base plugin
+	* Transforms all unhandled files to/from StringValue objects
+* Script plugin
+	* Transforms `*.lua` files to their appropriate file types
+* JSON/rbxmx/rbxlx model plugin
+* External binary plugin
+	* User passes a binary name (like `moonc`) that modifies file contents
+
+## Roblox Studio Plugin
+With the protocol version 1 change, the Roblox Studio plugin got a lot simpler. Notably, the plugin doesn't need to be aware of anything about the filesystem's semantics, which is super handy.
+
+## Bi-directional syncing
+Quenty laid out a good way to handle bi-directional syncing.
+
+When receiving a change from the plugin:
+1. Hash the new contents of the file, store it in a map from routes to hashes
+2. Write the new file contents to the filesystem
+3. Later down the line, receive a change event from the filesystem watcher
+4. When receiving a change, if the item is in the hash map, read it and hash those contents
+5. If the hash matches the last noted hash, discard the change, else continue as normal

+## Contributing
+Pull requests are welcome!
+
+The `master` branch of both repositories have tests running on Travis for every commit and pull request. The test suite on `master` should always pass!

+The Rojo and Rojo Plugin repositories should stay in sync with eachother, so that the current `master` of each repository can be used together.
