// Changelog
//
// 2019-12-18 v1.1.0 First alpha release using the new cc/v3, gocc, qbe
// toolchain. Some primitive tests pass on linux_{amd64,386}. Not yet safe for
// concurrent access by multiple goroutines. Next alpha release is planed to
// arrive before the end of this year.
// 2019-12-26 v1.1.0-alpha.2: Second alpha release adds support for accessing a
// database concurrently by multiple goroutines and/or processes. v1.1.0 is now
// considered feature-complete. Next planed release should be a beta with a
// proper test suite.
