What's new in this version:

- Personal Subscriptions: OmniOutliner now has support for (optional) subscriptions! Subscriptions give you the latest version of the app, enabling every feature on every platform (including Pro features)—with a lower cost up front and predictable spending in the future. (If you prefer the traditional licensing model, that option also remains available: traditional licenses are investments which cost more up front, but save money in the long run.)
- Unified Trials: we’re unifying our trials to use a single, simple approach: you sign up for a trial, it lasts for two weeks, and then it ends without charging you.
- Omni Automation [PRO]: support for automation via JavaScript Plug-ins has been updated; detailed notes about automation enhancements and changes can be found in the API Reference Release Notes.
- Named Styles [PRO]: when duplicating a Named Style, the duplicate will appear directly under the original.
