Sigil release notes
- This Sigil release is a mix of bug fixes and new features for both epub2 and epub3 users. Some of the highlights for this release include:
- Fixed the bug on Windows where smart right single quotes used for apostrophes couldn’t be added properly added to a user word list. This one has been aroud for a while!
- Ability to limit/disable clipboard history saving (a new General Preferences setting). Please note that the clipboard history feature will behave exactly as it always has while Sigil is running. Meaning that anything added to the clipboard while Sigil is running will be available for pasting. The new preference setting merely dictates how many entries (if any) get saved to the Sigil ini file when Sigil closes. Set it to zero to keep Sigil from saving any of the clipboard history to the ini file.
- A new Spellcheck Dictionary Preferences setting that allows the user to include words with numbers in them.
- Two new Quick Launch Icons for plugins were added to the main menu. There are now a total of five available. [full version history]
