Autocomplete for ROS 2 commands apparently do not work in a terminal using ZSH. You can read more about the potential cause of this issue in this thread.
This is a minor release that re-enables autocomplete for ROS 2 commands in case you are using ZSH. This is based on a fix that was mentioned here.
Note: This was solely tested on Ubuntu 22.04 with ROS 2 Humble. It is possible that this issue might be resolved in the newer version of ROS 2 (Iron Irwini).
