PureScript v0.14.2 released

PureScript v0.14.2 has been released!

Below are a few highlights:

  • the unused identifier warnings added in the previous release now have better source spans
  • type class instance names are no longer required as the compiler will generate names for you
  • Installing purescript on Linux no longer fails due to a missing dependency

All other changes are internal refactoring.

Full release notes below:

Thank you to everyone who contributed to this release!


Wow! I did not know removing mandatory type class instance names had been so close to being implemented! :tada: :tada: :tada:


I have a bad habit of forgetting to rename these when I yank similar lines and end up with errors, or when I refactor a type and forget to update the instance name to match. I’m pretty happy with this being automatic for these reasons.


WOW… love not having to name my instances.

Yeah! … however, unnamed/anonymous/whatever-you-call-them instances don’t show up in the docs :frowning_face: https://github.com/purescript/purescript/issues/4109


I’m getting version 'GLIBC_2.29' not found on our CI server, which is Ubuntu 18.
I know I can solve this by upgrading to 19 or 20.

But is there another way?

You could build the compiler yourself from source, or alternatively wait for the next release, for which the prebuilt binaries will be built on Ubuntu 18.04. I think we might put one out sooner than the usual 6 week schedule because of this issue.

Thank you @hdgarrood, I will consider my options.
