electromagnetism - Field of moving charge / Lorentz; Liénard-Wiechert

First question here. I'm really confused at the moment. An electron moves at constant velocity, no acceleration

Wikipedia says here Lorentz:

$$\mathbf E=\frac{q}{4\pi\epsilon_0}\frac{1-v^2/c^2}{1-v^2\sin^\theta/c^2}\frac{\hat{\mathbf r}}{r^2},$$ which yields something like this:

---

Whereas here, Wikipedia says this and this,

$$\frac{E'_y}{E'_x} = \frac{E_y}{E_x\sqrt{1-v^2/c^2}} = \frac{y'}{x'},$$ which yields something like this:

Which one is correct? If you could explain me exactly the reason why one of them is correct, I give you a big imaginary hug.

Last question: In none of those fields is there any radiated energy, since there is no acceleration, correct?
