+
+* **Gated behind features**
+  * `ArgMatches::grouped_values_of` is now gated behind `unstable-grouped`
+* **Renamed Structs**
+  * `clap::ArgValue` => `clap::PossibleValue`
+* **Removed Methods**
+  * `App::license`
+* **Removed Macros**
+  * `crate_license!`
+* **Changed**
+  * `Arg::from` now differentiates between `multiple_values` and `multiple_occurrences`. If `--opt [val]...` was meant for:
+    - only multiple occurrences, use `[opt]... --opt [val]`
+    - both multiple occurrences and values, use `[opt]... --opt [val]...`
+  * `Arg::from(...)` will now use `multiple_occurrences` for a positional arg's `...`, rather than `multiple_values`.

+#### Features

+* **Added Settings**
+  * `AppSettings::DisableColoredHelp`
+* **Added Methods**
