Release notes

Sourced from pypandoc's releases.

pypandoc v1.13 - It's time for arm

Below is the big changes for pypandoc v1.13. As always, rleeases for pypandoc and pypandoc_binary can be downloaded from pypi.

• Change when we do source file verification (#344)
• pass path to _get_pandoc_version() on windows correctly (#345)
• Updated CI to produce arm builds off pypandoc_binary (#356)
• Updated docker file to use python 3.12x, and therefore fixed python c… (#357)
• Removed support for python 3.6 in CI environment
• Other various small CI/CD improvements and workflow maintenance

Another fun thing, is that this time, is the first in pypandoc history, that we share the minor version with "pandoc", funny how things work out some times.
