 New in 0.5.4:
 * fix expansion of `abs(power)` (#19797)
 * fix a wrong function option with `zeta/zeta2` (#19799)
 * fix wrong formula for `tan(...).imag()` (#19791)
 * fix `mpq_pythonhash` (#19310)
 * change hash type to `int64_t` (#19310)
 * expand `exp(m/n*pi*I)` with trig functions if they can be expanded
 (#19738)
 * start changing libtool version with each release
 * performance: in `exp_eval` check for `Pi` and `I` before trying to
 divide
 * performance: much less canonicalizations of GMP rationals
 * performance: cache pseries coeff accesses in `pseries::mul_series`
 * performance: `GinacFunction`s for `cot/acot`
 * C++11: add `override` where possible
