We have a new patch release: [Crystal 1.11.1 is released! - The Crystal Programming Language](https://crystal-lang.org/2024/01/11/1.11.1-released/)

This release includes fixes for some regression bugs introduced in 1.11.0. Thanks for the timely bug reports 🙇‍♂️

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](https://github.com/crystal-lang/crystal/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc) and file a bug: it will be fixed in the following patch version.

Builds are available on the supported platforms, check the [install page](https://crystal-lang.org/install) for details. That includes [docker images 🐋](https://hub.docker.com/r/crystallang/crystal/), [snapcraft](https://snapcraft.io/crystal), `.deb` and `.rpm` packages, Windows builds and the brew formula 🍺.

Happy Crystallizing!

I get this when trying to compile it with Crystal 1.11.0

```auto
Error: abstract `def Object#hash(hasher)` must be implemented by ReferenceStorage(T)

```

I think I’ll have to first downgrade via a binary release, then upgrade ^\_^;

Yes, a 1.11.0 compiler can only build a 1.11.0 compiler. That bug is fixed in 1.11.1.

Note: Termux always uses 1.10.1 as the base compiler instead of the latest stable, so it shouldn’t be affected
