Changes for version 1.45 - 2017-06-23
- port to 5.22 and maybe later versions, mostly based on the patch by Cindy Wang.
- added t/02_array_hash_weaken.t test case by Cindy Wang.
- bumped minimum version to 5.008003.
- added Canary::Stability, so minimum version doesn't keep it from compiling with older versions.
- Devel::FindRef - where is that reference to my variable hiding?
