Description

Dear Leaflet Plugin Maintainer,

We’re excited to announce the release of the **Leaflet V2.0 alpha version**! 🎉
This marks a significant step toward modernizing Leaflet’s architecture and aligning it with the modern JavaScript ecosystem.

## ⚠️ Key Changes in Leaflet 2.0

To ensure your plugin remains compatible, please take note of the following important updates:

- **Factory methods have been replaced by constructors:**
`L.marker(latlng)` ➜ `new Marker(latlng)`

- **The global `L` object has been removed:**
Use **explicit imports** instead:
`import { Marker } from 'leaflet'`

- **Util methods have been replaced with native browser methods:**
`Util.isArray()` ➜ `Array.isArray()`

- **Pointer events support:**
Pointer events are now supported in place of mouse and touch events.
