WordPress Theme Development standard had got stricter and stricter, since I began developing my own WordPress theme projects. With no choices, much code written for feature functionality was prematurely dead because of these hard standards.
Moved projects to GitHub was not a decision going with the times. After stopping submitting updates to WordPress Theme Directory, I packed each version of my project codes and upload them to my website server for my users to download (via HTTP). But limited by files management inconvenience and website speed, I transfered everything to GitHub at last, and publish the new version of my WP themes today: Nest 1.1.8 and Concerto 1.0.5.
