Yes, it's happening everywhere.

I believe it's related to these changes in the new release https://github.com/vuejs/vue/releases

Improvements

warn misspelled keys on prop validation object (#7198) d02bb37, closes vuejs/vue#7198

Yes, it seems the Vue now check properties to look exactly like in the documentation.

Vue2Leaflet is using a key called "custom" in the property in order to bind it to the method of the Vue2Leaflet object or the method of the underlying leaflet object.

It seems that you can no longer do that with Vue so I need to find a new way of doing this...
You can still use Vue v2.5.10 in the meanwhile.

@asifm @KoRiGaN, the props validation has been remove in Vuejs v2.5.13 as per this diff.

Closing as it should no longer be an issue with the last vue version.
