 ### Changelog:
 
+2021-04-14 - Upgraded the dwmblocks patch for statuscmd which changes the signalling mechanism from SIGUSR1 to SIGRTMIN which is likely to cause issues for those that already have a working setup. A compatibility option has been added which changes this back to SIGUSR1. Note that configuration was also changed.
+
 2021-04-07 - Added xkb patch
 
 2021-04-06 - Added the distributetags patch
