v0.5.0

Release notes

Added

• Command east build will now after every build step copy
  compile_commands.json, if found, from the build directory to the project
  directory. This makes job of locating this file easier for clangd. Help
  description for east build was updated to reflect that.

Changed

• Make east.yml optional for everything, except for the usage of east build
  command with --build-type option.
• Make apps key and samples key inside east.yml optional. This is useful for
  driver projects, which do not need apps, or any project that might not have
  samples.

Fixed

• Properly handle east build commands outside of applications and samples.
  This means that running east build command will default to plain west
  behaviour, as it should.
