+### Configuration overview
+
+`cibuildwheel` allows for easy customization of the various phases of the build process demonstrated above:
+
+|   | Option |   |
+|---|---|---|
+| **Target wheels** | `CIBW_PLATFORM` | Override the auto-detected target platform |
+|   | `CIBW_SKIP` | Skip certain Python versions |
+| **Build environment** | `CIBW_ENVIRONMENT` | Set environment variables needed during the build |
+|   | `CIBW_BEFORE_BUILD` | Execute a shell command preparing each wheel's build |
+| **Tests** | `CIBW_TEST_COMMAND` | Execute a shell command to test all built wheels |
+|   | `CIBW_TEST_REQUIRES` | Install Python dependencies before running the tests |
+
+A more detailed description of the options, the allowed values, and some examples can be found in the [Options](#options) section.

 Changelog
 =========
 
+### 0.5.0
+
+- `CIBW_ENVIRONMENT` added. You can now set environment variables for each build, even within the Docker container on Linux. This is a big one! (#21)
+- `CIBW_BEFORE_BUILD` now runs in a system shell on all platforms. You can now do things like `CIBW_BEFORE_BUILD="cmd1 && cmd2"`. (#32)
+
 ### 0.4.1
 
 - Fixed a bug on Windows where subprocess' output was hidden (#23)
