Literature and Latte has released Scrivener 2.3.1, offering a number of improvements that take advantage of some of the new features in OS X 10.8 Mountain Lion. You can now easily tweet your daily writing session goal via the Twitter icon in the Project Targets panel, use Notification Center if Growl isn’t installed (or force Scrivener to use Notification Center even with Growl installed), and bring up a QuickReference or Quick Look panel from the binder, corkboard, outliner, or synopsis search results using Quick Look gestures (three-finger taps by default). Additionally, the app has been code-signed to comply with the new Gatekeeper security feature. The update also adds a new option for saving KindleGen source files along with the .mobi file, and improves the “Capitalize ‘i’” function. Among many other fixes, the release works around a system bug that added extra spacing above images when a line height multiple is applied, and squashes a bug with new .doc, .docx, and .odt importers that could cause a hang with certain files. It’s available in two versions from the Literature and Latte Web site’s downloads page — one for 10.6 Snow Leopard and later (also available from the Mac App Store) and one for 10.4 Tiger and 10.5 Leopard. ($45 new from Literature and Latte and the Mac App Store, free update, 30.4 MB (32.5 MB for OS X 10.4/10.5 version), release notes)
