If you use homebrew on macOS, then you can get Inkscape 0.92 by running:
brew install caskformula/caskformula/inkscape
(For non homebrew people, here's a glossary: formula => package built from source, tap => repository, cask => package redistributing an upstream binary)
This formula originates from the inkscape formula in the homebrew-gui tap. However, recently the homebrew-gui tap has been deprecated. In the case of Inkscape, the cask is considered the successor package. But since the inkscape cask is limited to official releases (or third party releases nominated by the Inkscape project), the cask will stay at 0.91.
So for the time being, I'll be maintaining the inkscape formula in this tap. Any contributions/improvements are welcome: https://github.com/caskformula/homebrew-caskformula
