I am truly sorry. I take full responsibility for my actions.
It was not remotely my intention to cause any of the subsequent side effects.
At the time of posting, I didn't know about any embargo. My contact had told me there was no embargo, and her contact had told her the same thing.
As someone who follows the 4-weekly PHP release cycle and compiles it from source, my intention was to alert others in a similar position to be aware of the importance/urgency of the updates.
That clearly backfired in a pretty wild fashion. I have learned my lesson.
