 ### Changelog ###
 
 main:
+ * Change licence from `MIT` to `MIT OR Apache-2.0`.
  * Moved `Opts::parse_map` into newly introduced `alloc` crate, making it accessible for `no_std` users.
  * More generic & flexible help API: removed forced newline, moved error writer to `StandardErrorUsageWriter`,
     generalised "Usage" line in standard full writer, enough public constructs to roll a custom help writer.
