Schmitz Running with Crayons has issued [1]Alfred 3.4.1, preventing incompatible workflows from loading in macOS 10.12.4 Sierra and later (if they contain an older version of a third party Alfred Workflow library). The keyboard-driven launcher updates the JSON output script format with new features (including add per item variables and add per mod customizable images), fixes the snippet database cache to correctly update when snippet triggers are duplicated, reduces workflow trigger connection constraints (enabling the Snippet Trigger feature to be connected to input objects), and fixes the Screen Saver system command in macOS 10.13 High Sierra. (Free for basic functionality, £17 for [2]Powerpack, 2.7 MB, [3]release notes, 10.9+) References 1. http://www.alfredapp.com/ 2. http://www.alfredapp.com/powerpack/ 3. http://www.alfredapp.com/changelog .
