- *
- * The accidental release of 2.5.9d1 was due to 3 factors:
- *
- * 1. The codebase got overhauled for the sake of WordPress Coding Standards compliance,
- *    one requirement of which is that files be named after the name of the class in them;
- * 2. The renamed folder was not added to Subversion version control due to an unexpected
- *    unfamiliarity with the system and its command line interface;
- * 3. The Stable Tag field in the Readme header was used for the package version because
- *    the related field is lacking, and the use of file headers for release configuration
- *    is uncommon.
