As Lukas Smith mentions in his latest post to his blog, the release of PHP 5.3 that was originally slated for today has been put off just a bit longer.
It almost happened, but it didn't for now. Originally we planned to release today. But again a few issues came up, even with Johannes deciding that sleep is for the weak, it just seemed unwise to announce the release today. So we pushed things back a few days, so the new date is June 30th (meaning it will be a Tuesday release).
We'll announce this as soon as its posted as stable to the PHP.net website, so keep an eye out on Tuesday for this greatly anticipated release!
