OmniPlan 3.13.1 for Mac adds a new “Plug-Ins” window, accessed from the Automation menu, for managing Omni Automation plug-ins.
It also includes a number of bug fixes that make it a better citizen on macOS 10.15 Catalina. It fixes a crash that could happen on exporting Reports; fixes a hang that could happen when subscribing to a web calendar with a never-ending event; deals with a system change that could cause corrupted change log files; and it removes some code, otherwise unused, that triggers a not-needed notification alert.
Read the release notes for all the awesome details. Happy planning!
