+## [0.4.0] - 2022-12-30
+
+### Added
+
+- Toolbar to highlight all call nodes of a specific function/method, expand their ancestors to reveal them, and hide other irrelevant nodes.
+- Integration with the new [fvalues](https://github.com/oughtinc/fvalues) library, highlighting dynamic parts of formatted strings in the detail pane.
+- Show the total cost of OpenAI API calls in each call node, assuming a price of $0.02 per 1000 tokens.
+- When running a recipe:
+  - Automatically start the server in a background process if it's not already running. This can be disabled by setting the environment variable `OUGHT_ICE_AUTO_SERVER=0`. Run `python -m ice.server stop` to kill the process.
+  - Automatically open the recipe in the browser. This can be disabled by setting the environment variable `OUGHT_ICE_AUTO_BROWSER=0`.
+  - Log the URL instead of printing it.
+- Environment variables `OUGHT_ICE_HOST` and `OUGHT_ICE_PORT` to configure the server host and port.
+
+### Changed
+
+- **Breaking trace file format change:** Traces are now stored in a directory with multiple files instead of one large file. This makes loading large traces in the UI much more efficient. Old trace files can no longer be loaded.
+- Instances of dataclasses are serialized as JSON objects instead of strings using `dataclasses.asdict` so they have a readable structure in the detail pane.
+
+### Fixed
+
+- Fixed SQLite connection error which sometimes occurred when running async functions decorated with `@diskcache`. 
+- Replaced hardcoded `/code/papers/` path (which only made sense in the old docker container) with environment variable `PAPER_DIR`.
+- Added empty `py.typed` file to the package for type checkers.
