A new release has rolled out: Crystal 1.8.2 is released! - The Crystal Programming Language
This patch release contains a couple minor bugfixes in the stdlib, one of them a regression from 1.8.1, and one minor bugfix in the compiler codegen.
While we have tested it against several known and sizeable projects, that doesn’t preclude the existence of regressions. If you find an issue, please check the issue tracker and file a bug: it will be fixed in the following patch version.
