Sigil-1.1.0 represents a mix of bug fixes and new features for both epub2 and epub3 users. Some of the highlights for this release include:

Dark mode suport for Windows Linux and macOSX. Mac is the only one of the three platforms where Qt inherently supports the system-level dark mode.

A brand-new higher-contrast icon set for Sigil has been contributed by BeckyEbook. Thanks for all your contributions to this version @Becky!

Sigil’s preference widgets have been redesigned to fit on smaller screens and to make room for future preference. Make sure you take a look around. Everything is still there, but some things have been regrouped and relocated.

Platform-specific Dark Mode details:

On Windows, darkmode is most commonly controlled by the darkmode settings in the latest version of Windows 10’s settings. It won’t work “on the fly” like many apps from the Windows Appstore, so you’ll have to restart Sigil if you change your system settings to see the settings take effect. To override the system setting (or to enable dark mode on versions of Windows that don’t officially have a dark mode), use the SIGIL_USES_DARK_MODE environnment variable (0 = off, anything else = on).

On Linux, Sigil has made changes to try and honor all platform themes that users define for their Qt apps on their desktop of choice. So theme managers like qt5ct or kvantum should work well with changing Sigil’s look. There might be a bit of color/qss tweaking to do, but all-in-all, I’ve seen good results with a myriad of themes (dark and light). If you’d like to opt-in to Sigil’s own included dark palette, set the FORCE_SIGIL_DARKMODE_PALETTE environment variable before launching Sigil. That will cause Sigil to ignore platform themes/overrides and to use the same dark palette that Windows uses.

On macOSX, Dark mode should just work. Qt has added a lot of inherent support for Mac’s dark mode and Sigil has incorporated that support. Even on-the-fly time-of-day changes should work with Sigil.
