=========
+- :bug:`322 major` `SSHClient.exec_command
+ <paramiko.client.SSHClient.exec_command>` previously returned a naive
+ `~paramiko.channel.ChannelFile` object for its ``stdin`` value; such objects
+ don't know to properly shut down the remote end's stdin when they
+ ``.close()``. This lead to issues (such as hangs) when running remote
+ commands that read from stdin.
+
+ A new subclass, `~paramiko.channel.ChannelStdinFile`, has been created which
+ closes remote stdin when it itself is closed.
+ `~paramiko.client.SSHClient.exec_command` has been updated to use that class
+ for its ``stdin`` return value.
+
+ Thanks to Brandon Rhodes for the report & steps to reproduce.
