Sigil 0.9.0 is the first full post Sigil 0.8.7 release. It includes **all** of the changes and improvements from our Sigil-0.8.900 series of pre-releases and it has shown itself to be stable in our tests. The changes from our last pre-release Sigil-0.8.901 are almost all bug fixes:

  • Add “Use Bundled Python” option to bring sanity and choice to Python3 Interpreter selection
  • Merge EmbeddedPython code across platforms and fix python flags for all platforms
  • Properly build translation base.ts to prevent blank message fields being generated by tr()
  • Update to the latest translations from transifex
  • Allow PrettyPrint_Gumbo to condense whitespace where allowed
  • Fix bug in PluginRunner auto-repair modified xml (opf, ncx), do not check xml with xhtml wellformed check
  • Fix bug in plugin epub3 interface, conversion of properties with null strings to None
  • Restore ability to override hunspell dictionary locations on Linux with SIGIL_DICTIONARIES env var
  • Restore ability to build Sigil against system hunspell libraries on Linux
  • Adjust to try to find system hunspell if bundled hunspell is not built/installed
  • Fix hang/slowness in TOC creation when huge number of headings all exist in the same file
  • Performance speedups for NCX writing to help with slow ToC Creation
  • Fix bug for better detecting comments in
  • Fix bug for Adding Blank xhtml files to an epub3
  • Fix bug for Issue 140 – TOC gets cut-off under some platforms (lxml needs utf-8 not unicode)
  • Add cmake option INSTALL_BUNDLED_DICTS to enable/disable installation of bundled hunspell dictionaries
  • Allow SIGIL_DICTIONARIES env var to specify multiple paths (colon delimited)
  • Fix bug in error message creation
  • Identify woff files as fonts when importing epubs
  • Fixes for nbsp being potentially “lost” when linking in stylesheets and when splitting and merging chapters
  • Fix for lost whitespace inside text containing tags when pretty printing
  • Workaround for broken QShortCut in Qt 5.4.X see Issue 149
  • cleanup up some compiler warnings

One new “feature” is that the Mac OS X Package has been code signed.
It is hoped this release will provide a stable and up-to-date version of Sigil while development work begins on adding some additional epub3 support features.

The Sigil-0.9.0 release can be downloaded from:

Don’t Forget FlightCrew
Please note, the epub2 validator FlightCrew has been converted to a plugin for Sigil 0.8.900 and later.
This plugin reamins unchanged from the last release and can be downloaded from the official Sigil-Ebook flightcrew repository if you have not already installed it.

Attention Mac OS X Users
Per the recommendation of, see, due to bugs and the age of Apple’s internal Tcl library, you should also download and install ActiveState’s ActiveTcl Community Edition.

To get the latest bug fixes, Sigil-0.9.0’s embedded Python has been linked with the very latest version: Tcl

We may not redistribute this Package with Sigil due to ActiveState’s binary non-redistribution policy.

So please download and install this version of ActiveState’s Active Tcl Community Edition, until we get a chance to do our own build of Tcl from source for future releases. ActiveState is a primary contributor to and a respected and trusted source for python and tcl/tk related binaries on both Windows and Mac OS X.
