What's new in CallbackRegistry 2.2
Version 2.2 includes support for monitoring hidden mounting points and cached reads and writes.
Before CallbackRegistry 2.2 the filter only processed non-cached requests, i.e. requests going to the file system. However in some cases several read and write operations can be performed in "cached" mode when the data is read/written from/to cache without affecting the disk. Such operations were not tracked. Starting with CallbackRegistry 2.2 cached operations are tracked as well.
See release notes for a list of breaking changes, caused by the introduced feature.
Also passthrough rules have been added in version 2.2. These rules let you specify exceptions to set access and callback rules.
