The deprecation log is a highly useful feature which tells you if deprecated code is currently in use. There is only one side effect when enabling the deprecation log: The filesize can grow very fast if you got either many deprecation code in use or only some but a very often visited site.

Therefore it is very hard to analyze the log file. The extension deprecationloganalyzer tries to help you by filtering the duplicates. Instead of searching a 500mb file, you will see only 11 unique errors.
