Fixed

• config no longer accepts null values, as the underlying Properties store won't allow them (https://github.com/edvin/tornadofx/issues/792). The set function that takes Pair still accepts null as the value, but will remove the key if the value is null.
• the di() delegate no longer calls out to the DIContainer for every access, effectively caching the lookup (https://github.com/edvin/tornadofx/issues/837)
• More efficient timer for delayed runLater calls (https://github.com/edvin/tornadofx/pull/836)
• runAsyncWithProgress cannot target an UI element with no parent, will no throw Exception with warning (https://github.com/edvin/tornadofx/issues/873)

Changes

• App.scope is overridable
• DefaultScope deprecated, use FX.defaultScope instead
• The Workspace inside the scope of a UIComponents will assume the Workspace it is docked in (https://github.com/edvin/tornadofx/issues/806)
• Kotlin 1.3.11
• bindSelected for ViewModel gets modifier (https://github.com/edvin/tornadofx/issues/823)
