or messages, though typically this is turned off.

**Features:**
|
||||
|
||||
* Advanced logging, with different log levels and hot reloading of the log level (no ticket)
|
||||
|
||||
**Bugs**:
|
||||
|
||||
* Respect Firebase "quota exceeded" response for topics, block Firebase publishing for user for 10min ([#289](https://github.com/binwiederhier/ntfy/issues/289))
