The 15.2.1 license file has been updated for hot fix 0403. Please note that there is also a breaking change for the Markup control.

If you have have done an SVN update and wish to continue using version 15.2.1.0221 you will need to rename two files
  1. SigCodejock Wrapper 15.2.1\AppSrc\SigCjLicense_v15.2.1.0221.pkg
    to
    SigCodejock Wrapper 15.2.1\AppSrc\SigCjLicense_v15.2.1.pkg
  2. SigCodejock Wrapper 15.2.1\AppSrc\ SigCjW_MarkupLabel 0221.pkg
    to
    SigCodejock Wrapper 15.2.1\AppSrc\ SigCjW_MarkupLabel.pkg

We have a meeting scheduled for later this month, how we handle Codejock Hot Fixes is high on the agenda.
