+## [0.2.0] - 2020-06-23
+
+### Additions
+
+- You can now specify default values for array properties of parsable types.
+  The default values are overridden if the user provides at least one value
+  as part of the command-line arguments.
+
+### Changes
+
+- This release of `swift-argument-parser` requires Swift 5.2.
+- Default values for all properties are now written using default initialization
+  syntax, including some values that were previously implicit, such as empty
+  arrays and `false` for Boolean flags.
+  
+  *Migration:* Specify default values using typical Swift default value syntax
+  to remove the deprecation warnings:
+  
+  ```swift
+  // old
+  @Flag() var verbose: Bool
+  // new
+  @Flag() var verbose = false
+  ```
+  
+  **_Important:_** There is a semantic change for flags with inversions that do
+  not have a default value. In previous releases, these flags had a default
+  value of `false`; starting in 0.2.0, these flags will have no default, and
+  will therefore be required by the user. Specify a default value of `false` to
+  retain the old behavior.
+
+### Fixes
+
+- Options with multiple names now consistently show the first-declared name
+  in usage and help screens.
+- Default subcommands are indicated in the help screen.
+- User errors with options are now shown before positional argument errors,
+  eliminating some false negative reports.
+- CMake compatibility fixes.
+
+The 0.2.0 release includes contributions from [artemnovichkov], [compnerd], 
+[ibrahimoktay], [john-mueller], [MPLew-is], [natecook1000], and [owenv]. 
+Thank you!
