=== Changelog evaluation ===
Each function/method has its own changelog. However, how they are written has introduced inconsistencies into the documentation.

=== TODO ===
Determine the official route for:
  * Order: Do newest PHP versions go on top or bottom?
  * Format: Is it PHP 5, 5, 5.0, or 5.0.0?
  * Information: Would the documentation make sense without the changelog entries? It should.

Next, evaluate each changelog and ensure it adheres to our official scheme. 

And lastly, document this scheme within the HOWTO.
