CCSv4.2.0 is now available.
The full image is available at: http://processors.wiki.ti.com/index.php/Download_CCS
The patch is available via Update Manager inside CCS. The update check runs once a week but you can run it manually by going to Help -> Software Updates -> FInd and Install
The release notes are available here: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_ccstudio/CCSv4/CCS_4_2_0/exports/ReleaseNote.htm
Most of the changes in the release are bug fixes and updated device support however you will notice some changes in the project wizard as it now allows you to select from some example templates.
Note that the full image will include updated compiler and target content packages but the patch does not. You can also get the updated compiler from Update Manager. The latest target content packages are available here: http://software-dl-1.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/index.html
