Release Notes and Upgrade Information

This is version 2 of the Raspberry Pi Alarm Clock and Media Player software.

If you are installing onto a fresh Raspberry Pi SD card image, the installation
instructions are unchanged from the published instructions.

If you are upgrading a previous installation:

1. Copy the tgz file in this zip archive onto the /bootfs partition of the SD card

2. Log into a command prompt shell on the Pi and enter the following commands
       sudo apt-get -y update
       sudo apt-get -y upgrade

3. Extract the fresh tarball archive and run the installer as per the original instructions.
*************************************************************************************
The clock's zip archive contains two PDF files, a 'tgz' file (also known as a tar-ball) and
this readme file.

The PDF addendum file outlines some additional release and debugging information.

The PDF installation file contains step by step installation instructions including
screenshots that could not be included with the print-edition articles. After the
article was prepared for publication, the GUI for the Raspberry Pi Imager programme
was changed, so the PDF file covers both the previous and current versions of the
imager programme.

The tgz file is the one that needs to be copied to the SDMMC card when you are preparing
it. NOTE: THIS MEANS YOU SHOULDN'T COPY THE WHOLE ZIP FILE TO THE SDMMC CARD, just the
tgz file!

Refer to the magazine articles for more information about this project.
