Schmitz Telestream has released [1]ScreenFlow 4.5.2, which squashes a bug introduced in the previous maintenance release (see '[2]ScreenFlow 4.5.1,' 28 May 2014) that prevented default export filenames from matching document names. The screencast recording app fixes a hang that occurred when opening documents with a high zoom factor, improves performance when opening documents with zoomed up timelines and many clips with audio waveforms, and fixes a memory leak related to modifying the speed of a clip with an audio waveform. For a complete rundown of the new features, read the PDF release notes from [3]Telestream's support page. Note that as of this writing, the [4]Mac App Store version of ScreenFlow remains at version 4.5.
