v0.8.0
Major Initial Release
SenseLogs is a fast log library designed exclusively for serverless apps using NodeJS.
While there are many other good logging libraries, that claim to be fast, they were not designed for serverless and so are bigger and slower than necessary.
Serverless apps have special requirments like minimizing cold-start time, dynamic log level and filtering control without redploying and being able to capture detailed context and request information without modifying your app. SenseLogs is designed to do this and more.
This is the first public release of senselogs. This module has been used for a while as the logging library for the SenseDeep serverless developer studio.
