 	- 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.
+
+1.3.1 - 2022-05-11
+	- Updated installation scripts and instructions to reflect changes in
+		Raspberry Pi OS Release 2022-04-04.
+		
+1.3.2 - 2022-08-08
+	- Fixed typo in dbadmin.php that prevented adding new When Discovered
+		items.
+	- Fixed bug in create.php that prevented the page from working.
+	- Fixed bug in config.php that prevented banners from being modified.
+	- Fixed bug where action_by and action_reason were not preselected for
+		subsequent searches in search.php.
+	- Fixed bug in about.php and gpl.php that still used old $mts_db
+		database handle.
+	- Removed the server session directory option in config.php
+		Miscellaneous settings. For this to make sense, you'd have to have
+		shell access to the server and if that's the case, you'd be able
+		to make the necessary database changes as well.
+	- Fixed opendrs-initial.sql to make the default banner colors match
+		the ones in common.php.
+	- Created changelog.php for use by the "changes" link on the About
+		page so kiosk terminal users don't get dead-ended in the CHANGELOG
+		text file with no way to get back to the app.
+	- Extensive code cleanups/updates in all php files to make application
+		compatible with php8 and eliminate php warnings in apache2 error
+		log file.
+	- For Raspberry Pi:
+		- Updated server-setup.sh to attempt to install the php-mysqli package
+			for compatibility with php8.
+		- Chromium browser will use the printer designated as the local
+			default if it is selected as such in the Cups printer
+			configuration.
+
+1.3.3 - 2023-10-03
+	- Restricted the ability to change the report date and time when 
+		creating or editing a writeup to only logged in users. This is to 
+		prevent reporters from backdating writeups, causing them to possibly 
+		be missed.
+	- For Raspberry Pi:
+		- Updated the Webmin custom command scripts to use whatever user is 
+			logged into Webmin instead of the user "pi" which may not exist 
+			if rpi-imager options were used to set a different initial user
+			when the SD card was created.
