+## `0.9.0`
+
+### Breaking changes
+
+- Added two new process spawning functions - `process.create` and `process.exec`, removing the previous `process.spawn` API completely. ([#211])
+
+  To migrate from `process.spawn`, use the new `process.exec` API which retains the same behavior as the old function.
+
+  The new `process.create` function is a non-blocking process creation API and can be used to interactively
+  read and write stdio of the process.
+
+  ```lua
+  local child = process.create("program", {
+    "cli-argument",
+    "other-cli-argument"
+  })
+
+  -- Writing to stdin
+  child.stdin:write("Hello from Lune!")
+
+  -- Reading from stdout
+  local data = child.stdout:read()
+  print(buffer.tostring(data))
+  ```
+
+- WebSocket methods in `net.socket` and `net.serve` now use standard Lua method calling convention and colon syntax.
+  This means `socket.send(...)` is now `socket:send(...)`, `socket.close(...)` is now `socket:close(...)`, and so on.
+
+- `Runtime::run` now returns a more useful value instead of an `ExitCode` ([#178])
+
+### Changed
+
+- Documentation comments for several standard library properties have been improved ([#248], [#250])
+- Error messages no longer contain redundant or duplicate stack trace information

+
+## `0.8.7` - August 10th, 2024

   Check the documentation for the `luau` standard library for more information.
 
 - Implemented support for floor division operator / `__idiv` for the `Vector2` and `Vector3` types in the `roblox` standard library ([#196])
