10. Changelog¶
This file is an informative list of the notable changes that have been made to the Project 2 specification.
In other words, this document is just a useful resource to quickly skim an informal explanation of changes made to various parts of the specification. Nothing in this document should be interpreted as requirements and/or clarifications on their own.
The text of the specification itself is the only normative documentation of requirements and wording, so you must read the relevant sections of the specification itself.
The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
