Just a quick note to those using the Desk Mess Mirrored theme and any Child-Themes of it, the latest version (2.0) is now set to its first Release Candidate (RC). Please feel free to have a look around this site to get an idea of the visual changes (note the new typography) as well as other aesthetic changes.
If you are interested in looking at the code, feel free to visit the GitHub repository: https://github.com/Cais/desk-mess-mirrored
Also to note, the Multi Child-Theme is also at its 2.0-RC1 version as well. The code for it can be found on GitHub as well: https://github.com/Cais/multi
IF you wish to upgrade with the RC versions, once the final versions of these themes are released you will be able to update as you have done in the past … in the terms of WordPress version 2.0 is newer than version 2.0-RC1, etc.
