Changelog (taken from https://github.com/gleam-lang/gleam/blob/main/CHANGELOG.md)

v0.25.1 - 2022-12-11
- New Gleam projects are now configured to explicitly install rebar3 using
  GitHub actions erlef/setup-beam.
- A better error message is now shown when attempting to use a function within a
  constant expression.
- Changed float size limit in bitstring expressions to 16, 32 or 64, when static.
  Also allowed dynamic size.
- New Gleam projects are created using GitHub actions erlef/setup-beam@v1.15.0.
- Fixed a bug where returning an anonymous function from a pipeline and calling
  it immediately without assigning it to a variable would produce invalid Erlang
  code.
- Fixed a bug where the formatter would remove the braces from negating boolean
  expressions.

v0.25.0 - 2022-11-24

v0.25.0-rc2 - 2022-11-23
- Fixed a bug where Gleam dependency packages with a `priv` directory could fail
  to build.
- Fixed a regression where Elixir and Erlang Markdown code blocks in generated
  documentation would not be highlighted.

v0.25.0-rc1 - 2022-11-19
- Generated HTML documentation now includes the `theme-color` HTML meta tag.
- The `use` expression has been introduced. This is a new syntactic sugar that
  permits callback using code to be written without indentation.
- Nightly builds are now also published as OCI container images hosted on
  GitHub.
- Fixed a bug where the build tool would not hook up stdin for Gleam programs it
  starts.
- Fixed a bug where using a record constructor as a value could generate a
  warning in Erlang.
- Fixed a bug where the build tool would use precompiled code from Hex packages
  rather than the latest version, which could result in incorrect external
  function usage in some cases.
- Fixed a bug where the warning for `todo` would not print the type of the code
  to complete.
- Fixed a bug where `try` expressions inside blocks could generate incorrect
  JavaScript.
- Generated HTML documentation now includes all static assets (but the web
  fonts), so that it can be accessed offline or in far future once CDNs would
  404.
- New Gleam projects are created using GitHub actions erlef/setup-beam@v1.14.0
- The `javascript.typescript_declarations` field in `gleam.toml` now applies to
  the entire project rather than just the top level package.
- The formatter now adds a 0 to floats ending with `.` (ie 1. => 1.0).
- New projects require `gleam_stdlib` v0.25.
