## Changes for version 2.027 - 2021-03-06

- no changes from 2.026_04

## Changes for version 2.026_04 - 2021-03-02

- define and use C macros in PP for shorter, more comprehensible XS

## Changes for version 2.026_03 - 2021-02-28

- got_complex_version change to defeat FreeBSD 10 false positive for complex funcs
- trig functions like asin($perl_scalar) return NaN for >1 again

## Changes for version 2.026_02 - 2021-02-25

- implement PDL::Type::real etc
- native complex numbers need check_lib as FreeBSD <10 has no complex trig

## Changes for version 2.026_01 - 2021-02-19

- native support for complex numbers - thanks @fantasma13
