Bug fixes
- Windows MTP device driver: Ignore failure to enumerate objects inside non-root folders
- There are apparently a lot of devices out there that fail in this way. So rather than aborting the scan simply ignore the folder.
- Book list: Fix a regression in the previous release that broke dragging to select multiple books
- Content server viewer: Fix reload book not actually reloading until the browser is also refreshed
- E-book viewer: Fix occasional false warning about highlight being overwritten
- E-book viewer: Fix detection of selected highlights when all text is selected
- Fix an error when embedding metadata into a large number of books
- When updating metadata in EPUB 2 files and no language is specified, do not remove the
tag as this causes epubcheck to complain. Instead set the language to "und" - Wireless device driver: Remove the timeout for initial connection
- Use an icon rather than a color to report errors in fields and the search box
- Conversion dialog: Regex builder: Workaround bug in Qt that prevented searching for non breaking spaces in the wizard used to test search expressions
- Spell check dialog: move down after correcting word, not up
