Update to 0.2.4:

Sigil v0.2.4 2010.08.12.
    - fixed a problem with updating image paths for images with the same filename but coming from
    different parent directories (issue #501)
    - added a new "Merge With Previous" context menu action for XHTML files in the Book Browser
    (issue #265)
    - changed Tidy to handle the common typing mistake of ending entities with a ':' instead
    of a ';' (issue #535)
    - fixed a bug where double-clicking a file in the Book Browser for a file that was already
    opened in a tab switched that tab back to Book View; the tab now retains whatever View
    it was in previously
    - newly opened tabs now default to the View of the current tab (issue 468)
    - re-engineered the locations where Sigil stores its work files; the system-provided temp
    folder is now used; this should alleviate some permissions issues on certain machines,
    especially Macs (issue #404)
    - Sigil now prevents the renaming of files in the Book Browser to filesystem invalid names
    (issue #493)
    - changed the keyboard shortcut that opens the Replace dialog from Cmd+H to Cmd+Shift+F
    on Macs only; Cmd+H is used by Mac OS X for window hiding (issue #477)
    - fixed an issue with Sigil using XHTML 1.0 for OPS doctypes, instead of XHTML 1.1
    (issue #503)
    - several files can now be marked as having the Text semantic type (issue #522)
    - fixed an issue with Direction: All in book wide searching skipping last XHTML file
    (issue #520)
    - fixed an issue with the declared XML encoding not being picked up if it was wrapped
    in single quotes instead of the more standard double quotes
    - fixed an issue where the user could avoid the warning dialog for book-wide searching in
    Book View if he switched to this mode in Code View, and then switched back

Sigil v0.2.3 2010.06.22.
    - fixed an issue with the new data from one view sometimes not being saved in the final
    epub when switching to the other view
    - worked around a Qt focus issue causing current tab data to sometimes not be saved;
    this was uncovered by fixing the hang-on-save issue, which was caused by the same
    underlying problem (issue #466)

Sigil v0.2.2 2010.06.20.
    - simplified the resource locking mechanism; should eliminate the hang-on-save issue
    - fixed a problem with BookView chapter splitting sometimes not being registered on save,
    causing duplicate content (issue #450)

Sigil v0.2.1 2010.06.18.
    - XHTML files that specify two different encodings are now fixed by removing the incorrect one
    - Sigil now checks the XML encoding attribute for an encoding before the HTML metatag
    and charset; should now be more compatible with Calibre created epub books
    - created/used 16px version of all icons; icons in menus are not blurry anymore (issue #121)
    - the Find&Replace dialog now uses the currently selected text (if any) as the default search
    term (issue #370)
    - fixed issues with unnecessary reloads of the code view (issue #412, issue #398)
    - fixed an issue with the HTML file filter in the open file dialog not correctly filtering
    files (issue #416)
    - fixed an issue with files without extensions not being saved in the final epub (issue #400)
    - fixed an issue with XPGT resources sometimes being saved blank (issue #433)
    - fixed a regression that made it impossible to add removed headings back into the TOC
    (issue #439)
    - fixed a problem with some file-wide replacements reverting
    - fixed a problem with the opened tabs not being updated until the user gave them keyboard
    focus when a file-wide replace was performed (issue 408)
    - fixed a problem with Book View not reflecting changes done in Code View when the
    Code View was used for editing, and then the tab closed
    - use of custom synchronization primitives should resolve most infrequent hang bugs
    - fixed a problem with the search not progressing in Book View find&replace when using
    recursive replacements
    - fixed an issue with inserting images that have apostrophes in the filename (issue #391)
    - TOC text now has leading and trailing whitespace trimmed, and inner whitespace condensed
    (issue #422)
    - an empty ALT attribute is now added to <img> elements that don't have them (issue #406)
    - added the build time to the About dialog, showing date and time in UTC
