4.0.0 (2017-10-30)

Bug Fixes

• Throw error if a release rule is invalid (0495801)
• Use Node 8 promisify instead of pify (bd19733)

Features

• Add logs and debug (6961dd8)
• Throw regular Error for unexpected errors (dc6ea59)

BREAKING CHANGES

• Expect to be passed logger in options. Require semantic-remantic >=9.0.0.
• Do not wrap unexpected errors in a @semantic-release/error. This way, in case of unexpected error (wrong release rule for example) semantic-release will fail and return with an exit code
