@@ -1,3 +1,64 @@+## 1.4.0.0++### Breaking changes++- Added `style...Set` family of functions ([PR #104](https://github.com/fjvallarino/monomer/pull/104)).+- `Composite`'s `onChange` event is now sent to its `handleEvent` function, not to its parent; the type of the+  generated event was updated to reflect this change. The rationale is that since `onInit` is sent to+  `handleEvent`, having `onChange` sent to its parent was confusing. At the same time there was not an easy way+  in `handleEvent` to know when the model changed. Widgets that want to report model changes to its parent can+  use `Report`/`RequestParent`; an example can be found in `ColorPicker` ([PR #71](https://github.com/fjvallarino/monomer/pull/71)).+- `Timestamp` is now a newtype. Enforce use of this type instead of `Int` when appropriate ([PR #103](https://github.com/fjvallarino/monomer/pull/103)).+- `Timestamp` was renamed to `Millisecond`. The rationale is that since both timestamps and durations are used frequently in calculations (and in the context of Monomer timestamps and durations indeed represent time in milliseconds), having separate types for Timestamp and Duration caused more harm than good ([PR #107](https://github.com/fjvallarino/monomer/pull/107)).+- `compositeMergeModel` (previously `customModelBuilder`) now receives `WidgetEnv` as its first parameter ([PR #114](https://github.com/fjvallarino/monomer/pull/114)).+- `compositeMergeReqs` now receives `parentModel` and `oldModel` too ([PR #114](https://github.com/fjvallarino/monomer/pull/114)).+- `mergeRequired` now receives an extra value as its first parameter, usually `WidgetEnv` ([PR #122](https://github.com/fjvallarino/monomer/pull/122)).++### Fixed++- Properly handle `SetFocusOnKey` for `textArea` ([#80](https://github.com/fjvallarino/monomer/issues/80)).+- Lens tutorial sample code ([PR #95](https://github.com/fjvallarino/monomer/pull/95) and [PR #98](https://github.com/fjvallarino/monomer/pull/98)). Thanks @Clindbergh!+- ColorPicker's numericFields vertical alignment ([PR #108](https://github.com/fjvallarino/monomer/pull/108)).+- Differences in glyphs positions used by `FontManager` and nanovg; temporary workaround ([PR #105](https://github.com/fjvallarino/monomer/pull/105)).+- `nodeInfoFromKey` relies on `nodeInfoFromPath` to retrieve information instead of fetching it directly from `WidgetEnv`'s `widgetKeyMap`, which can be stale ([PR #110](https://github.com/fjvallarino/monomer/pull/110)).+- Glyph positioning issues in `FontManager`; removed workaround added in #105 ([PR #125](https://github.com/fjvallarino/monomer/pull/125)).+- Will attempt to fall back to rendering on the main thread if threaded rendering setup fails ([PR #131](https://github.com/fjvallarino/monomer/pull/131)).+- Space leak in StyleUtil's mergeNodeStyleState ([PR #132](https://github.com/fjvallarino/monomer/pull/132)).++### Added++- Utility functions `rectFromPoints`, `nodeInfoFromKey`, `nodeInfoFromPath` and `findParentNodeInfoByType`.+- Allow setting the window icon via AppConfig ([PR #79](https://github.com/fjvallarino/monomer/pull/79)). Thanks @Dretch!+- Support for breaking text lines at character boundaries ([PR #86](https://github.com/fjvallarino/monomer/pull/86)). Thanks @toku-sa-n!+- Read-only mode for `textField`, `numericField`, `dateField`, `timeField` and `textArea` ([PR #93](https://github.com/fjvallarino/monomer/pull/93)). Thanks @Dretch!+- The `scroll` widget now supports a `thumbMinSize` configuration option that allows setting a minimum thumb size ([PR #100](https://github.com/fjvallarino/monomer/pull/100)).+- New field `_weAppStartTs` in `WidgetEnv`, complementary to `_weTimestamp`, representing the time in milliseconds when the application started. Added utility function `currentTimeMs` that returns their sum with a polymorphic type ([PR #103](https://github.com/fjvallarino/monomer/pull/103)).+- Several sizeReq helpers ([PR #106](https://github.com/fjvallarino/monomer/pull/106)).+- `compositeMergeEvents`, for completeness ([PR #114](https://github.com/fjvallarino/monomer/pull/114)).+- Support for symbols and other keys in `keystroke` ([PR #117](https://github.com/fjvallarino/monomer/pull/117)).+- New constructor (`buttonD_`) and `ignoreParentEvts` configuration option to `button` ([PR #123](https://github.com/fjvallarino/monomer/pull/123)).+- Allow disabling auto scale detection with `appDisableAutoScale` ([PR #128](https://github.com/fjvallarino/monomer/pull/128)).++### Changed++- The `keystroke` widget now supports the `Backspace` key ([PR #74](https://github.com/fjvallarino/monomer/pull/74)).+- `style...` family of functions now combine new attributes with the existing ones ([PR #104](https://github.com/fjvallarino/monomer/pull/104)).+- `radio` and `optionButton` now only trigger `onChange` when their value changes. `onClick` was can be used to replicate the previous `onChange` behavior ([PR #134](https://github.com/fjvallarino/monomer/pull/134)).++### Renamed++- Utility functions for retrieving `WidgetNode` information ([PR #75](https://github.com/fjvallarino/monomer/pull/75))+  - `findWidgetByPath` -> `findChildNodeInfoByPath`.+  - `findWidgetBranchByPath` -> `findChildBranchByPath`.+  - `findWidgetIdFromPath` -> `widgetIdFromPath`.+- Composite merge related ([PR #114](https://github.com/fjvallarino/monomer/pull/114))+  - `customModelBuilder` -> `compositeMergeModel`+  - `CompositeCustomModelBuilder` -> `MergeModelHandler`.++### Removed++- Dependencies on `OpenGL`, `Safe`, `scientific`, `unordered-containers`, `directory`, `HUnit` and `silently` ([PR #70](https://github.com/fjvallarino/monomer/pull/70)).+ ## 1.3.0.0  ### Added
