  • This release consists entirely of fixes for reported issues, and contains no new features.


  • Fixed hang which would occur if Spotlight was blocked on indexing when bringing up a source picker (as in multi-file search or text factory execution).

  • The application no longer claims to be able to edit "Java Web Start" files, which should prevent the OS from inappropriately opening them after downloading.

  • Fixed bug in which the first right-arrow gesture in a text document would have no effect when the document had been opened with soft wrapping turned on and the insertion point was at the very beginning of the document.

  • Fixed a cluster of bugs which conspired to prevent image windows from opening up with correct size and placement; the image's dimensions are now listed in the Window menu as well.

  • Fixed bug in which keyboard equivalents including the Shift key couldn't be set properly in the "Menus & Shortcuts" preferences.

  • Fixed crash which would occur when using the "New..." button in an FTP browser window while the item list was empty.

  • Fixed bug in which horizontal scrollbar calibration would get out of whack after deleting (or shortening) the longest line in the file, and then inserting text elsewhere to create a line that was longer than the previous record holder.

  • Fixed bug in which the line number bar would show incorrect line numbers following the beginning of a folded range of text.

  • After a conversation with Gruber, changed the UTI conformance for net.daringfireball.markdown from public.text to public.plain-text. This will fix QuickLook's failure to display Markdown files (it would show a document icon instead).

  • Changed the name of the "Data File" pseudo-language to "Text File", and added ".txt" and ".text" as default mappings to that language (in addition to the existing ".data" and ".dat'").

  • Fixed bug in which files which should have triggered a privilege escalation when opened did not, and instead reported a 10004 error.

  • Fixed a bug in which changes to display configuration would cause windows to be incorrectly reshaped in some situations. (Typically when an external display was removed from a laptop, and the window was located on the external display and was larger in either dimension than could be displayed on the laptop screen.)
