ngx-popper is an angular wrapper for the Popper.js library.


As of version 6.0.0 popper content runs in onPush change detection strategy, therefore forceChangeDetection is no longer necessary and is removed

As of version 4.0.0 ngx-popper now use innerHTML binding for string popper i.e:

<div popper="some text"></div>

This should make no difference but you should be aware.

As of version 4.0.0 popper.model is now popper-model, due to some angular-cli issues, if you are referencing this please update your references.
