A number of issues were discovered and resolved, warranting a new release of Ion to represent the current state of development in the alpha. No breaking changes have occurred between releases, but new features have been added. Specifically, this release features the addition of both herestrings and heredocs.

Ion should now be much more usable now than the previous release. Critical issues around SIGPIPE have been resolved, and many other critical issues have been fixed as well. The issues that remain are relatively minor at the moment, but there is a known bug with globbing that can cause words with ? marks to disappear for non-single-quoted words. The next release will have that issue fixed.

Static binaries for Linux provided below.

A huge volume of changes have happened since the last release. For those that are using this release, please report as many issues as you can find, submit feature requests, discuss issues on our GitHub Issues page, and seriously test out all of the signal handling and job control mechanics.
