Features

• Allow calling checkActivityFunctions without location object as an argument. This is already in the documentation, but wasn't implemented (#544)
• New single-spa:before-app-change and single-spa:before-no-app-change events. (#545 #547)

Fixes

• The CustomEvent.detail for single-spa:before-routing-event and single-spa:before-mount-routing-event now shows the new statuses for apps, meaning the status that the app will be in after the routing event finishes. Previously the current, older status was being reported as the new status. (#547)

Performance

• Refactor: only call activity functions one time per reroute. This is better for performance because each URL reroute results in less work. (#546)

Maintenance

• update tagline and description (#549)
• Add npm downloads badge (#542)
