=====
🛑 Breaking

• Renamed toHaveTagName to toHaveDisplayName (GreenGremlin)
  • This was done because Tag name indicates an HTML entity, but the matcher works with React Components which uses an internalProp displayName
  • When updating to 7.0.0 you should be able to just do a simple search and replace for this matcher across your codebase.

🍾 Improvements

• Add support for unboxed properties for toMatchElement. (@​blainekasten)
• Improve documentation for the entire repo. (@​blainekasten)
• Improve internal tests.
