            reboot.target.
    
1.1.2 - 2021-04-28
	- Added ability to export search results as a CSV file.
	- Fixed bug in server-setup.sh that resulted in an incorrect install
		location if the installation name was left at the default.
	- Fixed bug in server-setup.sh that resulted in failure to set the
		ownership of the installed server directory tree if the http
		user and group names were left at the default.
	- Updated and tested to support Raspberry Pi 4B hardware.

1.2.0 - 2021-05-05
	- Added ability to customize the terminology used for Device,
		Period, and Effective/Non-effective to make OpenDRS usable in
		a wider range of applications.

1.3.0 - 2022-03-05
	- Made several improvements to group functionality. The Writeup Groups
		page now displays all groups in a table instead of individually
		expandable sections. On the View Writeups and View Open Writeups
		pages, if a writeup is a member of only one group, clicking the
		icon will take you to the page for that group. If a writeup is
		a member of multiple groups, clicking the icon will take you to
		the detail page for that writeup where you can view or modify which
		groups the writeup is a member of. On the Search page, you can
		now choose which group(s) the results should include.
	- Made some improvements to the installation process for Raspberry Pi
		setup to accomodate the latest version of Raspberry Pi OS.
	- If setting up as a Raspberry Pi terminal/server, included the option
		to make the terminal a wireless access point if it connects to an
		ethernet network.
