#### Memory Monitoring GenServer
A new GenServer has been added to handle Process and Port memory monitoring, which is utilized by the OTP distribution layer. **All applications must be updated to this version to maintain memory monitoring capabilities.**
#### Configuration Restructuring
The following configuration variables have been moved from module-specific configuration to the root `:observer_web` configuration:
- `data_retention_period`
- `mode`
- `phx_lv_sckt_poller_interval_ms`
- `beam_vm_poller_interval_ms`
**Migration Guide:**
You may not need to update if you are relying on default values.
```elixir
# Before (v0.1.12)
config :observer_web, ObserverWeb.Telemetry,
mode: :observer,
data_retention_period: :timer.minutes(30),
phx_lv_sckt_poller_interval_ms: 5_000,
beam_vm_poller_interval_ms: 1_000
# After (v0.2.0)
config :observer_web,
mode: :observer,
data_retention_period: :timer.minutes(30),
