What is new in PreviewMD 0.5.0

Univocal is one app for all the text you read and write. Read Aloud reads the open document through Univocal 0.3.29 or later, highlighting the current word and sentence as it goes. Start it from the toolbar or Edit ▸ Read Aloud (⇧⌘R). The first time, allow PreviewMD in Univocal. Text is sent to Univocal on the same Mac only when you start reading.

### Added
- **Read Aloud** with word-by-word highlighting through
 [Univocal](https://univocalapp.com) (Univocal Connect protocol): the toolbar
 button or Edit ▸ Read Aloud (⇧⌘R) reads the preview, highlights the current
 word and sentence, and follows them as they scroll out of view (a manual
 scroll pauses following for a few seconds). Click a word while reading to
 jump there. Univocal's floating controls pause, skip sentences, change
 speed or voice, and stop; PreviewMD has no pause or stop of its own — while
 it reads, the toolbar button shows a reading state and ⇧⌘R does nothing. Code blocks, diagrams, images and front
 matter are skipped. Edits in Split view (or a reload from disk) restart
 reading at the current sentence; switching documents or to Edit view
 stops it. Univocal asks once for permission. If Univocal isn't installed,
 clicking the button shows a popover with a Download option. If an older
 version of Univocal is installed, the button offers an update.
