Sigil 0.9.14 will mark the last version that uses QtWebKit, and will be the last version to support editing in BookView. More here.

Be aware that Sigil-0.9.14 still enforces the need for epub3 to have and support an NCX so that it generates as backward a compatible epub as possible. This may be relaxed in future releases.

Please check the Sigil Wiki for important Sigil support links, additional resource downloads, and platform-specific trouble-shooting tips/requirements.
