+(Botched release due to Git mishap, oops!)
+
+## [7.0.0-rc.1] - August 23, 2021
+In Rojo 6 and previous Rojo 7 alphas, an explicit Vector3 property would be written like this:
+
+```json
+{
+    "className": "Part",
+    "properties": {
+        "Position": {
+            "Type": "Vector3",
+            "Value": [1, 2, 3]
+        }
+    }
+}
+```
+
+For Rojo 7, this will need to be changed to:
+
+```json
+{
+    "className": "Part",
+    "properties": {
+        "Position": {
+            "Vector3": [1, 2, 3]
+        }
+    }
+}
+```
+
+The shorthand property format that most users use is not impacted. For reference, it looks like this:
+
+```json
+{
+    "className": "Part",
+    "properties": {
+        "Position": [1, 2, 3]
+    }
+}
+```
+
+* Major breaking change: changed property syntax for project files; shorthand syntax is unchanged.
+* Added the `fmt-project` subcommand for formatting Rojo project files.
+* Improved error output for many subcommands.
+* Updated to stable versions of rbx-dom libraries.
+* Updated async infrastructure, which should fix a handful of bugs. ([#459])
+* Fixed syncing refs in the Roblox Studio plugin ([#462], [#466])
+* Added support for long paths on Windows. ([#464])

+
+## [7.0.0-alpha.4][7.0.0-alpha.4] (May 5, 2021)
+* Added the `gameId` and `placeId` optional properties to project files.
+    * When connecting from the Rojo Roblox Studio plugin, Rojo will set the game and place ID of the current place to these values, if set.
+    * This is equivalent to running `game:SetUniverseId(...)` and `game:SetPlaceId(...)` from the command bar in Studio.
 * Added "EXPERIMENTAL!" label to two-way sync toggle in Rojo's Roblox Studio plugin.
-* Fixed "Open Scripts Externally" feature crashing Studio ([#369][issue-369])
-* Updated dependencies, fixing `HumanoidDescription` ID issues.
+* Fixed `Name` and `Parent` properties being allowed in Rojo projects. ([#413][pr-413])
+* Fixed "Open Scripts Externally" feature crashing Studio. ([#369][issue-369])
+* Empty `.model.json` files will no longer cause errors. ([#420][pr-420])
+* When specifying `$path` on a service, Rojo now keeps the correct class name. ([#331][issue-331])
+* Improved error messages for misconfigured projects.

+
+## [7.0.0-alpha.1][7.0.0-alpha.1] (February 18, 2021)
+This release includes a brand new implementation of the Roblox DOM. It brings performance improvements, much better support for `rbxl` and `rbxm` files, and a better internal API.
+
+* Added support for all remaining property types.
+* Added support for the entire Roblox binary model format.
+* Changed `rojo upload` to upload binary places and models instead of XML.
+    * This should make using `rojo upload` much more feasible for large places.
+* **Breaking**: Changed format of some types of values in `project.json`, `model.json`, and `meta.json` files.
+    * This should impact few projects. See [this file][allValues.json] for new examples of each property type.
+
+Formatting of types will change more before the stable release of Rojo 7. We're hoping to use this opportunity to normalize some of the case inconsistency introduced in Rojo 0.5.

 ## [6.0.2](https://github.com/rojo-rbx/rojo/releases/tag/v6.0.2) (February 9, 2021)
 * Fixed `rojo upload` to handle CSRF challenges.

+## Local Development Gotchas
+
+If your build fails with "Error: failed to open file `D:\code\rojo\plugin\modules\roact\src`" you need to update your Git submodules.
+Run the command and try building again: `git submodule update --init --recursive`.

 ## Pushing a Rojo Release
 The Rojo release process is pretty manual right now. If you need to do it, here's how:
 
 1. Bump server version in [`Cargo.toml`](Cargo.toml)
 2. Bump plugin version in [`plugin/src/Config.lua`](plugin/src/Config.lua)
-3. Run `cargo test` to update `Cargo.lock` and double-check tests
+3. Run `cargo test` to update `Cargo.lock` and run tests
 4. Update [`CHANGELOG.md`](CHANGELOG.md)
 5. Commit!
     * `git add . && git commit -m "Release vX.Y.Z"`
-6. Tag the commit with the version from `Cargo.toml` prepended with a v, like `v0.4.13`
+6. Tag the commit
+    * `git tag vX.Y.Z`
 7. Publish the CLI
     * `cargo publish`
-8. Build and upload the plugin
-    * `rojo build plugin -o Rojo.rbxm`
-    * Upload `Rojo.rbxm` to Roblox.com, keep it for later
+8. Publish the Plugin
+    * `cargo run -- upload plugin --asset_id 6415005344`
 9. Push commits and tags
     * `git push && git push --tags`
 10. Copy GitHub release content from previous release
     * Update the leading text with a summary about the release
     * Paste the changelog notes (as-is!) from [`CHANGELOG.md`](CHANGELOG.md)
-    * Write a small summary of each major feature
-    * Attach release artifacts from GitHub Actions for each platform
