We are pretty sure that WordPress is using a slightly modified 1.0.1 of the trac.
If you could update the spelling of WordPress (with a capital P) that’d be appreciated whilst your at it 🙂
Another thing… All our links now use HTTPS, as such the URL should be:
• https://core.trac.wordpress.org
• https://plugins.trac.wordpress.org/
Also for WordPress themes:
• https://themes.trac.wordpress.org/
We also have a handful of other Trac installations also all using v1.0.1 for a few of our other WordPress projects:
• bbPress https://bbpress.trac.wordpress.org
• BuddyPress https://buddypress.trac.wordpress.org
• GlotPress https://glotpress.trac.wordpress.org
• Meta (Making WordPress) https://meta.trac.wordpress.org
