elm-format formats Elm source code according to a standard set of rules based on the official Elm Style Guide
Version 0.8.6 was not widely announced because of an issue with the npm installer on Windows, so check the 0.8.6 release notes as well. Below are the additional changes in 0.8.7.
New features:

Thanks to the contributions of many (see below), elm-format is now much faster. (Testers of the pre-release saw an 11x speedup on MacOS ARM, and a 4x speedup on other platforms.)

Thanks to @folkertdev for diagnosing and contributing the fix for a long-standing performance issue
where elm-format would take exceptionally long (and sometimes crash) on files contianing large expressions
such as long lists or many other AST nodes with many children.
Other than the performance improvements, there should be no other noticable changes from elm-format 0.8.2.
npm install -g elm-format
or download from the release page.
Two small improvements should make integration with code editors smoother with elm-format 0.8.2.
When installed with npm, elm-format startup time has been reduced by 70% (roughly 150ms).
And elm-format will now assume it should work in Elm 0.19 mode if autodetection of your Elm version fails.
If you still need to work with Elm 0.18 code, you must make sure that either elm-format is run from the directory containing your elm-package.json file (and there must not be a elm.json file in that directory), or elm-format must be invoked with the --elm-version=0.18 option.
exposing (..)The feature of automatically expanding exposing (..) in module lines has been removed.
While exposing everything in a module is an anti-pattern for production code,
it can be useful for rapid development sketches when the interfaces of your modules are not important.
To replace the old expansion behavior, elm-format now allows module lines without an exposing clause. Such lines will have the exposing automatically generated using the same logic that was previously used to expand exposing (..).
elm-format 0.8.2 also contains several bug fixes and other small changes.
See the CHANGELOG for details.
npm install -g elm-format
or download from the release page.
(..) in @docs linesStarting in elm-format 0.8.1, there is now only one official binary for each platform
(previously there was a seperate binary for Elm 0.18 and Elm 0.19).
elm-format now will auto-detect your Elm version using the following rules:
elm-package.json exists in the current directory, format in Elm 0.18 modeelm.json exists in the current directory, format in Elm 0.19 modeIf you need to run elm-format from a working directory that does not contain such a file
(or if you need to use elm-format in Elm 0.17 mode),
use the --elm-version=... command line argument to disable the autodetection.
elm-format 0.8.1 also contains several bug fixes for elm-format 0.8.0.
See the CHANGELOG for details.
