    - validation plugins that report no errors will now have "No problems found" appear in the Sigil Validation window.
    - validation plugins will auto accept/close the plugin runner window no matter the results
    - Windows installer now detects whether MS redistributable runtimes are already installed



Primarily Infrastructure Changes Toward Dual Epub2 / Epub3 support:

Sigil 0.8.900 (pre Sigil 0.9.0 series) 
    - Kill tidy and replace it with a combination of a specially modified Gumbo 
         parser that supports html5
    - Kill Xerces and XercesExtras.
    - Kill Boost, replace with C++ 11
    - Kill unused bundles.
    - Replace all "undefined - behaviour" use of "Null" References with proper 
         pointers across entire codebase to allow it to work with the latest 
         clang compilers
    - Completely revamp the build process to embed the Python 3.4 Interpreter 
         inside of Sigil and integrate it in, including as site-packages:
         [lxml, bs4, PIL, regex, six, html5lib].  This will allow plugins 
         that use the internal Python 3.X engine access to all of these 
         specialized packaes by default with no additional action
         needed by end users of their plugin.
    - Create our own version of BeautifulSoup4-4.4.0 called sigil_bs4 that 
         fixes lxml namespace bugs, fixes serialization/prettyprinting of 
         inline xhtml tags, and modifies the bs4 codebase so that a single 
         sourcecode works equally well on both Python 2.7 and Python 3.X
    - Replace internal opf and ncx xml processing and cleaning with a 
         combination of embedded Python 3.4, sigil_bs4 / lxml
    - Build hunspell as a shared library and then add a ctypes interface to allow
         plugins to spellcheck
    - Build our modified gumbo html5 parser as a shared library 
         and provide a bs4 ctypes interface to it for easy xhtml processing 
         in plugins that use Python 2.7 and Python 3.X
    - Allow plugins to auto-fix "text/html" media-types to "application/xhtml+xml"
    - Redesign the ebook source updates upon load process to use our modified 
         gumbo-parser
    - Begin the transition to allow for both epub2 and epub3 editing 
         (Note: epub3 editing is still incomplete)
    - Convert Flightcrew to become a Sigil plugin and replace it with
         a simple and fast internal sanity checker.
    - Update Hunspell dictionaries to be actual dictioanries and not word lists for en_US and en_GB
    - Updated other dictionaries to their most current version to match what is used in LibreOffice 5
    - Fix issue #54 modified date using local numerials when it should be
         using Arabic numerals per the spec.
    - Set the book to modified when font's are obfuscated.
    - Change FORCE_BUNDLED_COPIES build flag to USE_SYSTEM_LIBS. This flips
         the meaning of the flag. Now USE_SYSTEM_LIBS will enable using system
         libraries. Also, SYSTEM_LIBS_REQUIRED was added which will fail the
         cmake configure if any system libraries are not found instead of
         falling back to the bundled copy. Finally, this makes the build more
         consistent for Windows and OS X users.

      regardless if the user clicked no instead of yes.

    manifest (issue #800)
    - fixed a validation issue with the Meta Editor not adding the correct namespace prefix to some
    Dublin Core metadata element attributes

Sigil v0.4.0 ß1 2011.03.20
    - fixed an issue with CSS @import rules in the '@import "something.css"' format not being 
    recognized and thus not updated on import
    - removed the "CustomID" basic metadata entry from the Meta Editor; those wishing to use

    - fixed a rare issue with no tab opened by default when loading epubs
    - made the sigil.sh startup script more robust (courtesy of Craig Sanders) (issue #737)

    - fixed a regression ("Not a folder" error) with opening certain epub files on Mac and 
    Linux systems (issue #731) 

Sigil v0.3.3 2011.01.06.
    - added a small "Donate" button to the toolbar and a related entry in the Help menu 
    - added a .desktop file for the make install target (courtesy of Richard Gibert)
    - this time *really* worked around a Tidy bug that added blank lines to the start of <pre> 
    and <style> elements (issue #655)

    - fixed a rare input truncation problem when the input file contains a unicode nbsp and also
    specifies standalone="yes" in the XML declaration (issue #677)

    - added a new toolbar button for turning Tidy cleaning on/off; this option is also available
    from the Tools menu (issue #553)
    - added support for TrueType Collection fonts with extension TTC
    - InDesign (as of CS5) refuses to list the fonts it embeds in the OPF manifest of the epub 
    files it exports, even though the epub standard demands it. This causes Sigil to not pick up
    these fonts when opening such epub files. A workaround has been added that will detect such
    problematic epubs and then load the font files.
    - fixed a rare crash issue when loading epub files

Sigil v0.3.1 2010.11.07
    - added a new "Font Obfuscation" context menu for font files in the Book Browser; the user can
    now select (or de-select) the use of Adobe's or the IDPF's font obfuscation methods; this also
    resolves the problem where Sigil refused to open epub files that use such obfuscated fonts with  
    the message that the epub has DRM
    - fixed a validation issue caused by Sigil using "application/x-font-opentype" as the OPF
    mimetype instead of "application/vnd.ms-opentype"

    saved properly (issue #180)    
    - fixed an issue with certain path types not being correctly updated as a result of the 
    fix for issue #501 (issue #561)
    - the Book Browser now prevents adding files that already exist in the epub
    - previously, when adding external XHTML files through the Book Browser, any files (like CSS 
    stylesheets or images) that were linked from that file were included in the epub under a 
    different name if their original name was "taken"; this caused duplicates so this behavior 
    has changed: files whose names are "taken" are now skipped over (issue #482)    
    - fixed a rare issue that caused incorrect path updates for anchor links pointing to file names
    that were suffixes of other chapter file names, and the anchor had a fragment ID (issue #598)  
    - fixed an issue with the image paths in background-image CSS rules not being updated when
    the path changes (issue #594)
    - Sigil now informs the user that DRMed files cannot be opened, instead of just crashing
    (issue #624)
    - this time *really* fixed the "acknowledgments" error that was reported as fixed in RC1
    - fixed a crash on load (with an error dialog) issue on Linux systems occurring when multiple
    users on the same machine tried to use Sigil (issue #642)

    declared as UTF-16 (issue #617)

Sigil v0.3.0RC1 2010.10.08
    - fixed a validation issue caused by using the American spelling for "acknowledgments" where
    the OPF spec uses the British "acknowledgements" (issue #611)
    - Sigil now uses "application/x-font-ttf" as the media type in the OPF for TrueType fonts
    (issue #609)
    - on Mac OS X, the universal build now includes an x64 version of Sigil, and builds now
    use Cocoa instead of Carbon; support for Mac OS X 10.4 is dropped along with support for
    PowerPC Macs
    - fixed a problem with opening files from the Ubuntu "Open With" menu (issue #524)
    - made Tidy handle common user errors like "&co." in the HTML source instead of "&amp;co."
    - fixed a rare Tidy bug with disappearing spaces when the only whitespace in an element was 
    the newline following a start tag (issue #387)
    - changed the internal DOM engine from Qt's QDom to Xerces; this should also bring numerous
    bug fixes and performance improvements plus a small (~10%) decrease in memory consumption
    (issue #367)
    - updated Qt to 4.7: this should bring a 400%+ performance increase in Book View rendering 
    along with countless smaller performance improvements and bug fixes across the board
    - switched to the MSVC 10 compiler for Windows releases; should bring ~5% general performance 
    improvement 
    - fixed several crash/error problems relating to opening, saving and modifying epub files which
    have onerous file permissions set for internal content files (issue #574)
    - added a workaround for broken epubs created by other epub-producing software which caused
    a crash on certain searches with the Find dialog (issue #548)
    - fixed a problem with Book Browser's "Merge with previous" action if a file was previously 
    deleted from the Book Browser (issue #565)
    - fixed a problem with chapter splits being placed in the wrong reading order if a file was
    previously deleted from the Book Browser (issue #497)

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

    - 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

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,

    - 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

    - added two new WYSIWYG actions that work for both Views: "Insert SGF Chapter Marker" which
    inserts the old SGF horizontal rule chapter breaking marker and "Split On SGF Chapter Markers"
    which splits the current chapter according to the placement of these markers (issue #262)
    - chapter splitting now works in Code View
    - fixed an issue with Sigil adding "xmlns='http://www.w3.org/1999/xhtml'" to every element
