Last week we released version 4.0.0 of the honeybadger Ruby gem. This release includes a long-awaited feature which makes it even easier to customize your error reports before they are sent to Honeybadger. We also did some much-needed refactoring, and made a few removals and deprecations for good measure. Don't worry, though—most of the API remains unchanged, so upgrading should be a relatively painless process for most users.
