[twitter-dev] response when limit reached - when did this change?

[Moshe C.]

I used to get an HTTP "Bad request" error when passing the rate limit
and used that to make my process sleep.
Now this evidently changed and I am getting:
<?xml version="1.0" encoding="UTF-8"?>
<hash>
  <request>/1/statuses/user_timeline.rss?
user_id=12765&amp;count=100&amp;since_id=1626417105</request>
  <error>Rate limit exceeded. Clients may not make more than 20000
requests per hour.</error>
</hash>

Which was ignored and caused me to pound on the server.


When was this changed?
Is this new response subject to changes in the near future?

I couldn't fund the doc page on this.
