It's hilarious how WP devs are in a rush to use x.0 products like 5.3.0
They're only on 2.8.3 already in 30 days and possibly not done yet.

Somehow I do hope they force the 50% of people still on PHP 4 to stop using WordPress and search for other programs. It can only help other projects.

So:

1. force people to keep upgrading constantly to maintain security no matter how it keeps breaking everything

2. eventually make a version 50% of your base can't upgrade to because it won't work on their host, leaving them open to security issues

Should end well.

ps. Objects are not faster, they make it easy to cache bloated things but they certainly are not faster by any means. All that copying around in memory adds up. Running on 5.3 will give you a 5-15% speed boost over 4.4.9 but it doesn't magically thin bloated code.
