 1. Adding a reference to a note using the magnifying glass icon is possible even if not logged in. This results in a blank tech and shift.
-SOMEWHAT FIXED. If not logged in and the partview argument is not 1, redirects to login page. (This is not the optimal solution. There needs to be a specific view only state.)

 5.2.5 - 2026-02-10
     This is just a version number bump to get on a major-minor-patch
         scheme. There are no code changes for this release.
+
+5.3.0 - 2026-02-20
+    - Moved the template Create/Copy/Edit/Delete/Rename functionality to
+        its own page to make it less confusing and to fix some strange
+        behavior.
+    - Added global templates which can be used by anyone but can only be 
+        created, modified, or deleted by administrators. This makes it 
+        easier to employ standardized templates.
+    - Changed the character encoding of the database to utf8mb4 to enable
+        using emojis in text fields.
+    - Changed the insert link functionality. There are now two fields, link 
+        text, and URL. The full URL string will now not be displayed in the
+        note, since it frequently was too long and deformed the table, 
+        causing the user to have to scroll right to see the entire note. If
+        a URL is entered in the URL field and no link text is entered in the
+        link text field, the link will show up as just the last part of the
+        URL. For example, "http://somewhere.com/myfile.pdf" will show as
+        "myfile.pdf" in the note text. If text is entered in the link text
+        field, that is what will show as the clickable link in the note text.
+        NOTE: URLs in previously entered notes will not automatically be
+        converted.
+    - Changed the flag handling code to no longer dynamically create flag_ 
+        tables in the database to track assignments. This is now done using
+        a flagmap table.
+        NOTE: The database will be modified to support this and the
+        importation of the previous data will take some time during
+        installation.
+    - References will no longer be stored in the lognotes table with the note.
+        There is now a reflinks table that stores the link information.
+        NOTE: The database will be modified to support this and the
+        importation of the previous data will take some time during
+        installation.
+    - Various code cleanups to prevent php warnings in the logs if logging
+        is enabled.
+    - Validate all date and time fields to prevent user entered invalid date
+        formats from crashing php.
+    - Fixed profile page to automatically refresh page to show the results 
+        when a user changes their color preferences.
+
+5.3.1 - 2026-02-25
+    - Fixed bug reported as Issue 1 where failure to select an action for a
+        part entered in a lognote crashed php in logentry.php.
+    - Fixed bug where the prompt to set flags on reference chain appeared
+        even when no flags were available to select in logentry.php.

+# OpenLog #
+
+OpenLog is an online logbook application. It allows anyone with a web browser to read, enter, and search for notes on any subject. 
+
+The available shifts, employees, and subjects are easily configured. Notes can be referred to other notes and the entire chain of referenced notes can be displayed in a single page. This makes it convenient to track ongoing projects or actions on a particular piece of equipment over a long period of time. 
+
+Version 5.0 adds parts tracking functionality. Notes can have parts change information associated with them and maintenance/repair forms can be generated for parts. Parts related functions can be disabled to reduce clutter if they are not needed. 
+
+Version 5.1 adds scheduled maintenance functionality, which can also be disabled if not needed. Notes, parts, and maintenance forms can be searched for based on a number of criteria. 
+
+The look and feel of the OpenLog pages are easily changed. Settings that affect all users can be changed in the Administration menu. Each user can personalize his or her own settings in the My Profile menu. 
+
+No browser specific HTML is used in OpenLog, so it should be useable in any browser, and it has been tested using Google Chrome, Mozilla Firefox, Microsoft Internet Explorer, and Edge.
+
+## Prerequisites ##
+
+- Linux - The installer is written to automate installation on Debian based Linux servers, but OpenLog itself should run on any current Linux distribution, albeit installation will need to be accomplished manually. 
+- Apache2 - Current development is using version 2.4.65
+- MySQL or MariaDB - Current development is using MariaDB version 11.8.3
+- php - Current development is using version 8.4.11
+
+## Installation ##
+
+> [!NOTE]
+> These instructions are used to either install a new instance of OpenLog or upgrade an existing one.
+
+1. Unzip the OpenLog-x.x.x.tar.gz file you've downloaded into a convenient place.
+2. `cd OpenLog-x.x.x`
+3. `sudo ./install.sh`
+
+* The installer will check for installation of the required packages and prompt for their installation if not found.
+* You'll then be prompted for the webserver's install location. The default should work for standard installations.
+* You'll then be prompted for the installation location of this instance of OpenLog. You should come up with a unique name. 
+* If this directory already exists and contains an instance of OpenLog, you will be prompted to cancel the process or upgrade this instance.
+  * If you choose to upgrade, your OpenLog instance will be upgraded and you're done.
+* If this directory does not exist, it will be created and a new instance will be installed. You can have multiple instances of OpenLog running under different names in different directories. For example, if you wanted to create an Operations Log, you could enter `opslog`.
+  * In the Operations Log example referred to above, you could enter `OpsLog` or `Operations Log`.
+  * You'll br prompted for the name of the database to be created. You should choose something appropriate, like `opslog` for the example given.
+  * Next, you'll be prompted to enable the apache2 configuration for this instance.
+  *The new instance will now be installed and accessible. You will be given some important information.
+  > [!IMPORTANT]
+  > The default login credentials for the initial admin user are:
+  > login: `OpenLogAdmin`
+  > password: `OpenLog-1`
+  > Make note of these credentials, otherwise you will not be able to login and configure your new installation.
+  >
+  > It is highly recommended that you change the OpenLogAdmin user password and/or create your own admin user (with a secure password) and disable this default account after logging in for the first time.
+
+
+## History ##
+
+OpenLog was written to replace a creaky old inefficient error prone Access database which had in turn replaced stacks of paper logbooks. Now, with some improvements and over 15 years and 44000 notes later in a production environment, it's still going strong.
