Roadmap: 3.0 😎

[zkat]

This is the roadmap of major or breaking changes that are meant to land with [email protected]. Is there anything you'd like to see here? Feel free to start a discussion about it (under "ideas").

Probably breaking changes:

• Support for multiple diagnostics #47
• toplevel error footer #34
• More flexible and customizable ReportHandler situation #50
• split off DiagnosticReport + reporters into their own library? #25
• Replace snippets system with a "simpler" labels system #63

Stuff that can probably land sooner, but should be in by 3.0:

• Use auto-detection to figure out whether to make a URL clickable #49
• Derive macro: single field for multiple snippets #43
• Humanize panic handling? #22
• MietteReporter: handle wide characters? #4
• Wrap error messages to stay within the indented message block #51
• Feature Request: minimal or no output on an enum varient #65

Stuff we need to remember to do right before tagging the release:

• 3.0: Update test suite to reflect latest styling. #57
• 3.0: Update screenshots (and their alt text) to reflect latest styling. #58
• 3.0: Make sure all major features are documented in the README. #59
