v0.7.3

Highlights 🎉

• Includes the core set of changes required to make Slinky work well with Next.js (including module splitting). The Slinky docs site now is built with Next.js! (PR #588)

Breaking Changes ⚠️

• Slinky now requires Scala.js 1.9.0 or higher, but libraries published against older versions of Slinky should continue to work (PR #588)
• The interface to createPortal has changed, but libraries should not be affected since this is typically intended for end-users (PR #594)

Bug Fixes 🐛

• Fix stale version of components being rendered when hot reloading is used with module splitting (PR #588)
• Add support for the key parameter of createPortal (PR #594)
• Allow the cx and cy SVG attributes to be assigned to Strings instead of just Double (PR #617)
