The deprecation log is shown in the reports module. There has been a huge discussion whether or not the deprecation log should be turned on or of by default. I think it should be turned of because users are not interested in it at all. On the other hand if there is an easy way to deal with the deprecation log it is fine if it is turned on by default. Here are three suggestions for the deprecation log handling in the reports module to make it more user friendly.

1. Show the size of the deprecation log (if it is small you can leave it as it is)
2. Deactivate the deprecation log (at the moment you need to dive into the install tool and search for it to turn it off - in the text it is also suggested to turn it off when it gets to big)
3. Clear the deprecation log (especially when it is very large you might not want to waste that space)
