Carbon 1.7 is out and is backwards compatible with 1.0 through 1.6. It supports PowerShell 2. It contains mostly bug fixes and some enhancements.
There is now a Carbon support mailing list.
Enhancements
General
- Import-Carbon.ps1 now supports the 
-WhatIfswitch. - Import-Carbon.ps1 now hides verbose log messages when removing/importing Carbon even when supplying the 
-Verboseswitch because I think the verbose output is too verbose and not helpful at all. - Import-Carbon.ps1 now supports adding a prefix when importing the Carbon module (with the 
Prefixparameter) to avoid name collisions and follow best practices. 
Certificates
- Get-CertificateStore now supports non-standard, custom certificate stores.
 - Get-Certificate now supports non-standard, custom certificate stores.
 - Install-Certificate now supports non-standard, custom certificate stores.
 - Uninstall-Certificate now supports non-standard, custom certificate stores.
 
Bug Fixes
General
- No more silent errors when importing Carbon on Windows 2012 R2.
 
Certificates
- Get-Certificate no longer writes a silent error when a certificate does not exist. Instead, no error is written.
 
File System
- Install-Junction fails when target path is hidden.
 - Test-NtfsCompression fails when file/directory is hidden.
 - Test-PathIsJunction fails when tested directory is hidden.
 
Security
- Grant-Permission fails when item is hidden.
 - Grant-Permission doesn’t handle non-existent paths, causing cascading errors.
 - Test-Permission always returns 
$falsewhen testing leaf-level permissions and theApplyToparameter is provided, i.e. it doesn’t ignore inheritance/propagation flags on leaves.
