+# Chef Infra Client 15.6
+
+## Updated Resources
+
+## apt_repository
+
+The `apt_repository` resource now properly escapes repository URIs instead of quoting them. This prevents failures when using the `apt-file` command, which was unable to parse the quoted URIs. Thanks for reporting this [@Seb-Solon](https://github.com/Seb-Solon)
+
+## file
+
+The `file` resource now shows the output of any failures when running commands specified in the `verify` property. This means you can more easily validate config files before potentially writing an incorrect file to disk. Chef Infra Client will shellout to any specified command and will show the results of failures for further troubleshooting.
+
+## user
+
+The `user` resource on Linux systems now continues successfully when `usermod` returns an exit code of 12. Exit code 12 occurs when a user's home directory is changed and the underlying directory already exists. Thanks [@skippyj](https://github.com/skippyj) for this fix.
+
+## yum_repository
+
+The `yum_repository` now properly formats the repository configuration when multiple `baseurl` values are present. Thanks [@bugok](https://github.com/bugok) for this fix.
+
+## Performance Improvements
+
+This release of Chef Infra Client ships with several optimizations to our Ruby installation to improve the performance of loading the chef-client and knife commands. These improvements are particularly noticeable on non-SSD hosts and on Windows.
+
+## Smaller Install Footprint
+
+We've further optimized our install footprint and reduced the size of `/opt/chef` by ~7% by removing unnecessary test files and libraries that shipped in previous releases.

 # Chef Infra Client 15.5.15
 
 The Chef Infra Client 15.5.15 release includes fixes for two regressions. A regression in the `build_essential` resource caused failures on `rhel` platforms and a second regression caused Chef Infra Client to fail when starting with `enforce_path_sanity` enabled. As part of this fix we've added a new property, `raise_if_unsupported`, to the `build-essential` resource. Instead of silently continuing, this property will fail a Chef Infra Client run if an unknown platform is encountered.
 
-We've also updated the `windows_package` resource. The resource will now provide better error messages if invalid options are passed to the `installer_type` property and the `checksum` property will now accept uppercase SHA256 checksums.
