+  - Fixed handling of Unicode escape sequences
+  - Improved error handling for invalid escape sequences
+
+## v0.2.0 (2024-12-29)
+
+### Changes
+- Port [rack/query_parser.rb](https://github.com/rack/rack/blob/main/lib/rack/query_parser.rb) to make better compatible with rails/rack
+- Port [rack/spec_utils.rb](https://github.com/rack/rack/blob/main/test/spec_utils.rb)
+- Merge JSON with other structured data
+- Rename `axum_params::ParamsValue` to `axum_params::Value`, doesn't need use it directly
+
+## v0.1.0 (2024-12-25)
+
+### Features
+
+#### Unified Parameter Handling
+- Path parameters
+- Query parameters
+- Form data
+- Multipart form data
+- JSON body
+- All parameter types can be processed simultaneously
+- Every parameter type supports structured data (arrays and objects)
+
+#### Rails-like Tree-Structured Parameters
+- Nested parameter handling similar to Rails' strong parameters
+- Support for deeply nested structures with arrays and objects
+- Files can be placed at any position in the parameter tree, e.g. `post[attachments][][file]`
+- Seamlessly mix files with other data types in the same request
+- Automatic parameter parsing and type conversion
+- Handle complex forms with multiple file uploads in nested structures
+
+Example structure:
+```rust
+post: {
+    title: String,
+    content: String,
+    tags: Vec<String>,
+    cover: UploadFile,
+    attachments: Vec<{
+        file: UploadFile,
+        description: String
+    }>
+}
+```
