The following schedule should be used as a guideline for anyone still relying on TurkerView's old API infrastructure:

Endpoint	Scripts Affected	Empty Response	Removal
turkerview.com/api/	TVJS v9 (or below)	March 3rd, 2019	March 10th, 2019
api.turkerview.com	HIT Forker v1.0.6.1 (or below) MTurk Suite 2.4.6 (or below)	March 3rd, 2019	March 31st, 2019

We expect this to impact <3% of total users, so most likely you do not need to worry about this unless you've disabled TamperMonkey updating & have not manually updated existing scripts. You'd most likely know if this applied to you.

Developers
If you maintain a script that relies on one of these endpoints & need help porting to our more reliable API endpoints please let me know. There are developer docs available & I am happy to submit code where necessary.
