I've released BiwaScheme 0.7.0.
See the changelog for the list of bug fixes and new features.
Announce 1: Drop support of IE
I'm considering using newer JS syntaxes (like arrow functions, etc.)
starting from 0.7.0.
0.7.x will work on most of the modern web browsers, but may not work
on old browsers like InternetExplorer. See here if you need to run 0.7.x on them.
Announce 2: New script style
Currently BiwaScheme has two ways to run Scheme program.
The old style is deprecated because it is somewhat tricky. It is still supported but may be removed in a future version.
