- use Markdown with inline HTML instead of reStructuredText
- move file from docs/supportedsites.rst to docs/supportedsites.md
- update Makefile, README, etc
- use 'os.name' to decide between Windows/Linux build
- don't check Windows executable version number,
since Wine fails to run the executable and causes release.sh to stop
- update CHANGELOG on new releases
- change issue references to actual links
- replace "Unreleased" with new version and date
- fix filenames of old Windows executables
