When I do the sum

Sum[(a + (b + π n)^2)^(-1), n, -∞, ∞]

the result reads

$$beginarraycc
{ &
beginarraycc
fraccoth left(sqrta+i bright)+coth left(sqrta-i bright)2 sqrta & arg left(sqrta-i bright)geq -fracpi 2land arg left(sqrta-i bright)leq fracpi 2 \
fraccoth left(sqrta+i bright)2 sqrta+fraccoth left(sqrta-i bright)2 sqrta-frac1sqrta & textTrue \
endarray
\
endarray
$$

What is the meaning of True in the second result?

If I get rid of $pi$, the result is simply:

$$ frac-pi cot left(pi sqrt-a+pi bright)-pi cot left(pi sqrt-a-pi bright)2 sqrt-a$$

See Piecewise. It is like the cases environment in $LaTeX$. In native math, one would use "else" instead of True.

By the way, version 12 returns

$$begincases
fraccoth left(sqrta-i bright)+coth left(sqrta+i
bright)2 sqrta & arg left(b+i sqrtaright)geq 0 \
fraccoth left(sqrta-i bright)2 sqrta+fraccoth
left(sqrta+i bright)2 sqrta-frac1sqrta &
textTrue
endcases$$

Ok, so it really simply means "otherwise" or "else" or "in all other cases"?
