Welcome to the release notes for Scarb v2.4.0-rc4!
This quick release includes following small improvements.

Formatter emit option

Since this release, when formatting your project with scarb fmt you can use --emit stdout argument. With this argument, Scarb will not make any changes to the files on your disk. Instead, full new content of formatted files will be printed to stdout, prepended with their path. Files that had already been in a correct format will not be emitted.

Environmental variables in scripts

Since this release, all environmental variables inherited by Scarb will be passed to package scripts runtime. This will allow you, to read external variables inside your scripts.

Cairo Version

This version of Scarb comes with Cairo v2.4.0-rc4.
