Version: 1.8.0
Will sigil ever be compatible with the M1 processor?? I've tried multiple times this year (Nov 12, 2021 today) and it never works. Have a 2020 MacBook Air.

Version: 1.5.1
Just a note: This hasn't been a WYSIWYG editor in a while. The dev removed that portion of the app and split it off into a separate app called PageEdit (also open source).

Version: 0.9.14
I have used this app only once when Amazon was refusing my book in Calibre's mobi format and it saved my life. :-)
I opened with Sigil the epub generated by Calibre and generated the TOC (Tools/Toc/Generate at that time) then I opened the edited epub in Kindle Previewer or kindlegen and converted to mobi.
So 5 stars for this invaluable tool!

Version: 0.9.11
Developer's website does not exist anymore and Sigil is unable to download itself the update.
Aug 30 2015
Version: 0.8.3
Sigil 0.8.7 is out
https://github.com/Sigil-Ebook/Sigil/releases
Oct 18 2014
Version: 0.8.0
8.01 is out at http://sigildev.blogspot.it
A really nice and great application to create or edit epub.
My only complaints with these last versions (8.0 and 8.01) is that you can not paste text in the Replace field using key shortcut anymore.
It is not a tragedy, but it's not so comfortable activate the control-click menu every time you want paste the replace string in Search and Replace…
So before to upgrade take also a backup copy of previous version if it works for you.

Great software, unfortunately no longer under active development. See: http://sigildev.blogspot.com
I am still using it in Mavericks. I use Calibre also, which is constantly improving as an ebook editor.
