The biggest release since 1.0 with 251 changes in total.

Some highlights:

- Performance improvements for DWARF loader

- All targets support a native event loop

- Constants can have type declarations

- `Crystal::ALL_FLAGS` and `USER_FLAGS`

- Upgraded package dependencies, docker base images etc.

- Binaries for `aarch64-windows`

Impressive benchmarks. Reaching 1M msgs/sec on a 2 vCPU instance is a great showcase for Crystal. As a Crystal core member, I've always seen LavinMQ as a prime example of performance-oriented engineering, especially with how it handles I/O and minimizes syscalls to get the most out of the hardware.

If you want to see Crystal's concurrency and type system in a serious production environment, this is the project to check out. Kudos to the LavinMQ team for their work since 2020.

Hi everyone,

I wrote the original "Why Crystal?" blog post back in 2015 when Crystal was just v0.9.1.

Ten years and many versions later, I am revisiting that post to analyze the road to v1.20.

If you are interested in how a language matures from a syntax experiment to a high performance standard, this one is for you.
