Release Notes

FantasticFiasco/serilog-sinks-http (Serilog.Sinks.Http)

v9.0.0

⚡ Added

• #​311 [BREAKING CHANGE] Support specifying levelSwitch when creating the sink, thus adding the support to dynamically change the log level at runtime (contribution by @​yuriy-millen)

  Migration guide

  The parameter levelSwitch has been introduced to the methods Http, DurableHttpUsingFileSizeRolledBuffers and DurableHttpUsingTimeRolledBuffers. Please verify that the arguments pass by you to these methods still align with your intentions.

  To automatically mitigate this kind of new parameter issue in the future, move from using positional arguments to named arguments.

• #​262 [BREAKING CHANGE] Support specifying flushOnClose when creating the sink, thus adding the support to suppress sending unsent log events to the log server before closing the sink (proposed by @​murlidakhare, @​julichan, @​janichirag11 & @​prasadpaul53)
