# January 2018 - Windows Agent 4.12

## Release Overview

Release Date: 01/10/2018

- **Support for IIS Shared Configuration **We now support the discovery and profiling of apps when using IIS Shared Configuration. If enabled this will automatically disable HTTP module injection as a safeguard from potential runtime errors. We also now report IIS shared configuration info in agent diagnostics.
- **Profiler stability improvements**Fixed issues where either the profiler would shutdown in certain scenarios

## Release Features

- None

## Release Enhancements

**UNC Path Configuration Support**

- IIS apps that reside on a UNC path(i.e \\servername\sharedfolder\) will now be discovered properly

**APM Key Transaction Settings Update More Frequently**

- We now do not require full discovery to run or an agent restart for overriding APM Settings (Track, Summarize, Errors) to take effect. We sync these settings on a schedule to catch updates more frequently.

## Bug Fixes

- Fixed an issue where the agent’s INI file wouldn’t update in certain scenarios causing the profiler to shutdown
- Fixed how error handling works during app discovery so that it doesn’t affect other agent/profiler functionality
- Fixed scenarios where trace upload rules wouldn’t be honored correctly
