[logback-user] SLF4J 1.7.5 with LogBack

Hi Frederic,

The improvements in SLF4J 1.7.5 apply only to logger factories shipping 
in SLF4J. Moreover, the improvements to logback's logger factory, aka 
LoggerContext, were already applied in logback version 1.0.10.

Thus, for users of logback upgrading to slf4j 1.7.5 will not improve nor 
degrade performance. Note that for logback users upgrading from version 
1.6.x or 1.7.x to version 1.7.5 should be trivially easy and is recommended.
