====== Marlin RC2 Oct2012 Bukobot Firmware Changes ======

This version of the firmware was forked from the main Marlin Github repository (https://github.com/ErikZalm/Marlin) on 10 Oct 2012. The git head id of the repository is:
[[https://github.com/ErikZalm/Marlin/tree/bc27d809fb4232abd33c85f33ec2bb78d7ce3444|bc27d809fb4232abd33c85f33ec2bb78d7ce3444]].

The sections below list the file difference between each of the Bukobot firmware releases and the head at that time.

The difference was generated by executing the following command using the steps:

1) Create a local clone of the Marlin github repository (using the github client).
2) Open a github command window (using the github client).
3) Checkout the repository at the time it was branched using the following command:
<code>git checkout -f bc27d809fb4232abd33c85f33ec2bb78d7ce3444</code>
4) Copy the released bukobot firmware into the directory where you have done the checkout.
5) Display configuration file differences using the following commands:
<code>git diff Marlin/Configuration.h
git diff Marlin/Configuration_adv.h</code>
(The file changes are also visible from the github client).

Configuration.h and Configuration_adv.h were the only two files which were changed in all versions.
