 ## Version 0.5 (in progress)
 
-* Added `require_subcommand` to `App`, to simplify forcing subcommands. Do not "chain" with `add_subcommand`, since that is the subcommand, not the master `App`. Untested.

 * Evaluate compatibility with [ROOT](https://root.cern.ch)'s TApplication object.
     * Add way for subclasses to return remaining options rather than throwing error
 * Chained subcommands are not supported, once a subcommand is given the rest of the options go to that subcommand, rather than allowing multiple subcommands. This is currently intentional behavior, but multiple base level subcommands, like [`Click`](http://click.pocoo.org) supports, might be considered in the future.
+* Support case insensitive set and/or subcommands?
