- Implementation of some conservative additional multi-core support (mainly in graphics/media) using OpenMP. I'm taking baby steps here and will remain conservative in the use of multiple cores so stability of the browser isn't needlessly endangered.
- Update of the navigation button icons (again). Users have clearly indicated that the inverted color icons on glass and dark themes were less desirable. I've listened, and changed the icons for glass back to the pre-20 style but with added contrast, and made a distinction for dark personas (themes) where the icons are now simply inverted white (like in Firefox).
- Change for the color management system (CMS) so that Pale Moon now supports more types of embedded ICC profiles (including the already decade-old version 4 spec) and in the process fixing potential color issues on screens with images that embed such profiles.
- Update of the browser padlock code. You can now choose both a "modern" look (as introduced in version 19) and a "classic" look (as introduced in version 15, when this padlock feature was first added). It also removes some phantom spacing in locations where the padlock isn't used (thanks for the pointer, Sowmoots!). You can find instructions in the Pale Moon Tweak Guide (PMTG)
