how to upgrade from CI3.0-dev to CI3.0.0.

This is how I do my upgrade for several of my projects and it worked flawlessly.

Note:
#1. Before doing the steps below, make a BACKUP of your project files.
#2. Highly recommended:, use GIT or Mercurial on your current project and do a commit.

1. Read the changelog (differences CI3.0 dev between the final release of CI3.0) before proceeding.
2. Unzip the CI3 archive to a folder (we'll use ci3 for this)
3. Copy the files from ci3 to your project (example: system to system, application to application)
4. When you're done and you have GIT/Mercurial installed, just use the DIFF command to find and restore your changes (mostly the files of the applications/config folder)
