Crystal 0.32.1 has been released!
This release comes after a week of stabilizing the 0.32.0 with feedback mainly from the community. There were fixes and improvements that should unlock migrating to 0.32 in some contexts.
There are 6 commits since 0.32.0 by 6 contributors.
Let’s review some highlights in this release. And don’t miss the rest of the release changelog.
The main updates for 0.32 can be found in the release post of 0.32.0.
Compiler
With recent changes regarding how string interpolation is handled there were some issues with long heredocs strings. Due to some internal safety guards restrictions in the compiler a generic type can’t have more than 300 type arguments (probably reminiscent of that sparta movie). This 300 limit means that there can’t be more than 300 pieces in a string interpolation. Each piece is a continuous string literal or an interpolation. In this release a line break in a heredoc string will not generate a different piece. Read more at #8581.
Standard library
The HTTP::WebSocket’s on_close callback is now called upon any error kind and not only for IO::EOFError. Read more at #8552.
Next steps
Please update your Crystal and report any issues. We will keep moving forward and start the development focusing on 0.33.
It will also be helpful if your shards are run against Crystal nightly releases. Either Docker or Snap are the current channels to get them easily. This will help reduce the friction of a release while checking if the ecosystem is in good shape.
We have been able to do all of this thanks to the continued support of 84codes, and every other sponsor. It is extremely important for us to sustain the support through donations, so that we can maintain this development pace. OpenCollective and Bountysource are two available channels for that. Reach out to crystal@manas.tech if you’d like to become a direct sponsor or find other ways to support Crystal. We thank you in advance!
