* `addEventHandler` replaced with decorator [event](functions/event/event.md)
```python
@pyg2o.event('onInit')
async def evtInitFirst():
    print('Hello')
    
@pyg2o.event('onInit', 100)       # '100' is priority
async def evtInitSecond():
    print('World')
```
---
* Positional arguments inside event handles replaced with keyword arguments (see names of all keywords on the each event page)
```python
@pyg2o.event('onPlayerChangeColor')
async def evtColor(playerid, r, g, b):
    pass
```
---
* `callEvent` now also requires to pass keyword arguments instead of positional arguments
```python
@pyg2o.event('MyTestEvent')
async def testEvt(name, id):
    print(name, id)
    
g2o.callEvent('MyTestEvent', name = 'aurumvorax', id = 15)
# OR
g2o.callEvent('MyTestEvent', {'name': 'aurumvorax', 'id': 15})
# OR
args = {'name': 'aurumvorax', 'id': 15}
asyncio.create_task(pyg2o.callEvent('MyTestEvent', args))
```
---
* `cancelEvent` temporarily disabled
---
* `isEventCancelled` replaced with built-in function property `cancelled`, alongside with the `eventName`
```python
@pyg2o.event('onPlayerDropItem')
async def evtDrop(**kwargs):
    print(evtDrop.cancelled)
    print(evtDrop.eventName)
```
---
Now all constants should be called via **Constant** class
```pyton
import pyg2o

@pyg2o.event('onInit')
async def evt_init():
    print(pyg2o.Constant.SERVER_SIDE)
```
