Problems with Symbols, Low Severity (4)

	Change	Effect
1	Type of 1st parameter ip has been changed from unsigned int to long.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Base type of 2nd parameter on_tick_needed has been changed from *void()(lw_eventpump) to void()(lw_eventpump)**.	Replacement of parameter base type may indicate a change in its semantic meaning.

	Change	Effect
1	The default argument of 3rd parameter Size has been changed from 0 to -1.	Applications will pass an old default (compile-time) argument that may not be properly handled anymore. This may result in crash or incorrect behavior of applications.

	Change	Effect
1	Type of 1st parameter p1 has been changed from Webserver::HandlerConnect to Webserver::HandlerDisconnect.	Replacement of parameter data type may indicate a change in its semantic meaning.
