+
+## Removed Features
+
+The following features have been removed in version 2.0.0:
+
+- **IIS/ISAPI Integration**: Unmaintained since 2009. Windows users should use WSL2 with Apache httpd instead.
+- **AMQP Transport**: Experimental feature that was never fully completed.
+
+## Upgrade Notes
+
+### Breaking Changes
+
+1. **SSL/TLS Peer Validation**: SSL/TLS peer name validation is now enabled by default (AXIS2C-1700). Applications that previously connected to servers with invalid certificates will now fail. To restore the old behavior (not recommended), disable peer verification in your SSL configuration.
+
+2. **IIS Support Removed**: Applications using IIS integration must migrate to Apache httpd (running natively or via WSL2 on Windows).
+
+### New Dependencies
+
+- **json-c** (optional): Required for JSON support. Install via `apt install libjson-c-dev` on Debian/Ubuntu.
+- **nghttp2** (optional): Required for HTTP/2 support. Install via `apt install libnghttp2-dev` on Debian/Ubuntu.
